Hi,

I just installed a PCI serial card (RS422/485). I loaded the linux
kernel module driver, made the /dev/ nodes, looks fine but RXTX see only
my /dev/ttyS0 & /dev/ttyS1 RS232 ports and not the new ones. 

dmesg extract :
"Found Korenix JetCard 1402"
"ttyJ0 at I/O 0xdc00 (irq = 11) is a 16C950/954"
"ttyJ1 at I/O 0xdc08 (irq = 11) is a 16C950/954"


Any idea ?

Juilen

Did you change the import line in your .java file?

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Very strange, it looks like real ports for me : 

/dev # setserial /dev/ttyJ0
/dev/ttyJ0, UART: 16950/954, Port: 0xdc00, IRQ: 11
/dev # setserial /dev/ttyJ1

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

:)

i have a nokia 6260 phone , connected to my PC through Bluetooth (Virtual modem/serial port ) , i can connect my phone to PC also by using a DKU-2 cable

i know some AT Commands , i've got the whole AT Commands Set from nokia
i am using Windows XP-SP2
can anyone help me in a code or anything that .. 
sends an sms from the PC to customer , through the n6260 connected ??
and read sms and process the sm text , then respond to the customer again

i try AT+CMGS it works fine in HyperTerminal of Windows XP

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

Regards,
Thanasis.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

> Would you share with us how you do the rs232/rs485 in hardware?

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)
               {
                 System.out.println("Unsupported comm parameters: " +  
eUnsupported.getMessage());
               }
             }
             catch(TooManyListenersException eTooMany)
             {
               System.out.println("Too many listeners on comm port: "  
+ eTooMany.getMessage());
             }
           }
           catch(IOException eIO)
           {
             System.out.println("GPS port input stream exception: " +  
eIO.getMessage());
           }
         }
         catch(PortInUseException eInUse)
         {
           System.out.println("GPS port in use by another  
application: " + eInUse.getMessage());
         }

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();
         return StringUtils.contains(s[0], "uucp") &&
                 StringUtils.contains(s[0], "lock");
     }


     public static String[] groups() {
         String command =
                 "groups ";
         try {
             return OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
         return null;
     }

     public static void print(Object o[]) {
         for (int i = 0; i < o.length; i++) {
             System.out.println(o[i]);
         }
     }

     public static void tarXvf(File f) {
         String command =
                 "tar " +
                         " -xf " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
     }

     public static void chmodPlusX(File f) {
         String command =
                 "chmod " +
                         " +x " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

[1] See "Q.  How does rxtx detect ports?  Can I override it?"
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7/INSTALL

Thanks a lot. 
I use the command:
cvm 
-Dgnu.io.rxtx.SerialPorts=/dev/ttyM0:/dev/ttyM1:/dev/ttyM2:/dev/ttyM3:/dev/ttyM4:/dev/ttyM5:/dev/ttyM6:/dev/ttyM7 
myapp

It can list ports what I want.
Now I 'll test the main I/O function for my device.

And, yes , I obtained the armv5b-softfloat-linux-gnu/librxtxSerial.so from 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

and I tried several version about arm or xscale but they
will throw an exception :
java.lang.UnsatisfiedLinkError: /root/cvm_rmi/lib/librxtxSerial.so


ps: Also thanks for your patience of my poor English.

Excuse me sir
i thought that the serial ports on linux are /dev/ttyS0 or /dev/tty/S1 etc.
what is this M0/M1 etc?
PLEASER CLARIFY

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

                 }

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
java.io.IOException: Underlying input stream returned zero bytes

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Message-ID: <p060204abc039f5331115@[192.168.1.152]>

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!
  - Doug

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

[1.1] It was fun...

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

Hi,

I just installed a PCI serial card (RS422/485). I loaded the linux

my /dev/ttyS0 & /dev/ttyS1 RS232 ports and not the new ones. 

dmesg extract :

"ttyJ1 at I/O 0xdc08 (irq = 11) is a 16C950/954"


Any idea ?

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Very strange, it looks like real ports for me : 

/dev # setserial /dev/ttyJ0
/dev/ttyJ0, UART: 16950/954, Port: 0xdc00, IRQ: 11
/dev # setserial /dev/ttyJ1
/dev/ttyJ1, UART: 16950/954, Port: 0xdc08, IRQ: 11

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

i have a nokia 6260 phone , connected to my PC through Bluetooth (Virtual modem/serial port ) , i can connect my phone to PC also by using a DKU-2 cable

i know some AT Commands , i've got the whole AT Commands Set from nokia
i am using Windows XP-SP2
can anyone help me in a code or anything that .. 
sends an sms from the PC to customer , through the n6260 connected ??
and read sms and process the sm text , then respond to the customer again

i try AT+CMGS it works fine in HyperTerminal of Windows XP




any suggestions are welcome

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

> Would you share with us how you do the rs232/rs485 in hardware?

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Subject: [Rxtx] Problem on Mac OS X
Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();
         return StringUtils.contains(s[0], "uucp") &&
                 StringUtils.contains(s[0], "lock");
     }


     public static String[] groups() {
         String command =
                 "groups ";
         try {
             return OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
         return null;
     }

     public static void print(Object o[]) {
         for (int i = 0; i < o.length; i++) {
             System.out.println(o[i]);
         }
     }

     public static void tarXvf(File f) {
         String command =
                 "tar " +
                         " -xf " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
     }

     public static void chmodPlusX(File f) {
         String command =
                 "chmod " +
                         " +x " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
     }
}

public class OsUtils {

Message-ID: <p06230907c03600ce3ba5@[169.229.252.13]>

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

and JVM  is CDC1.0.1 .
And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
/dev/ttyS0
/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

[1] See "Q.  How does rxtx detect ports?  Can I override it?"

Thanks a lot. 
I use the command:

It can list ports what I want.
Now I 'll test the main I/O function for my device.

And, yes , I obtained the armv5b-softfloat-linux-gnu/librxtxSerial.so from 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

and I tried several version about arm or xscale but they
will throw an exception :
java.lang.UnsatisfiedLinkError: /root/cvm_rmi/lib/librxtxSerial.so


ps: Also thanks for your patience of my poor English.

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
java.io.IOException: Underlying input stream returned zero bytes
	at sun.nio.cs.StreamDecoder$CharsetSD.readBytes(StreamDecoder.java:415)
	at sun.nio.cs.StreamDecoder$CharsetSD.implRead(StreamDecoder.java:453)
	at sun.nio.cs.StreamDecoder.read(StreamDecoder.java:183)
	at java.io.InputStreamReader.read(InputStreamReader.java:167)
	at java.io.BufferedReader.fill(BufferedReader.java:136)
	at java.io.BufferedReader.readLine(BufferedReader.java:299)
	at java.io.BufferedReader.readLine(BufferedReader.java:362)
	at cz.darmovzalt.gps.Nmea.process(Nmea.java:89)
	at it.gps.Prova.<init>(Prova.java:24)
	at it.gps.Prova.main(Prova.java:48)

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

Thanks,

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Subject: [Rxtx] fixing rxtx configurations...you need to be root for this,
	right?
Message-ID: <p060204abc039f5331115@[192.168.1.152]>

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!
  - Doug

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

[1.1] It was fun...

My machine is MOXA  which has 8 serial port look like rj45 port. I must use 
a connector to transfer serial to rj45.

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

Hi,
Because I will remote control the machine which connect the rs232 device . 
So , I have a problem , I don't know that is the rs232 device connect to 
the machine. Maybe the device is turn off , or someone pull out the line. I 
should know
the device connection status.

How should I do?

Hi,

I just installed a PCI serial card (RS422/485). I loaded the linux
kernel module driver, made the /dev/ nodes, looks fine but RXTX see only
my /dev/ttyS0 & /dev/ttyS1 RS232 ports and not the new ones. 

dmesg extract :

"ttyJ0 at I/O 0xdc00 (irq = 11) is a 16C950/954"
"ttyJ1 at I/O 0xdc08 (irq = 11) is a 16C950/954"


Any idea ?

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

> Would you share with us how you do the rs232/rs485 in hardware?

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)
               {
                 System.out.println("Unsupported comm parameters: " +  
eUnsupported.getMessage());
               }
             }
             catch(TooManyListenersException eTooMany)
             {
               System.out.println("Too many listeners on comm port: "  
+ eTooMany.getMessage());
             }
           }
           catch(IOException eIO)
           {
             System.out.println("GPS port input stream exception: " +  
eIO.getMessage());
           }
         }
         catch(PortInUseException eInUse)
         {
           System.out.println("GPS port in use by another  
application: " + eInUse.getMessage());
         }

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();
         return StringUtils.contains(s[0], "uucp") &&
                 StringUtils.contains(s[0], "lock");
     }


     public static String[] groups() {
         String command =
                 "groups ";
         try {
             return OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
         return null;
     }

     public static void print(Object o[]) {
         for (int i = 0; i < o.length; i++) {
             System.out.println(o[i]);
         }
     }

     public static void tarXvf(File f) {
         String command =
                 "tar " +
                         " -xf " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
     }

     public static void chmodPlusX(File f) {
         String command =
                 "chmod " +
                         " +x " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

Thanks a lot. 
I use the command:
cvm 
-Dgnu.io.rxtx.SerialPorts=/dev/ttyM0:/dev/ttyM1:/dev/ttyM2:/dev/ttyM3:/dev/ttyM4:/dev/ttyM5:/dev/ttyM6:/dev/ttyM7 
myapp

It can list ports what I want.
Now I 'll test the main I/O function for my device.

And, yes , I obtained the armv5b-softfloat-linux-gnu/librxtxSerial.so from 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

and I tried several version about arm or xscale but they
will throw an exception :
java.lang.UnsatisfiedLinkError: /root/cvm_rmi/lib/librxtxSerial.so


ps: Also thanks for your patience of my poor English.

Excuse me sir
i thought that the serial ports on linux are /dev/ttyS0 or /dev/tty/S1 etc.
what is this M0/M1 etc?

Thanking you

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

                         CandidatePortPrefixes=Temp;
                 }

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:
:

Any idea?

P.S. I'm using Matlab everyday at my university for my research
activity. Good luck, Trent!!!

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Subject: [Rxtx] fixing rxtx configurations...you need to be root for this,
	right?
Message-ID: <p060204abc039f5331115@[192.168.1.152]>

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!
  - Doug

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

[1.1] It was fun...

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

Any idea ?

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Very strange, it looks like real ports for me : 

/dev # setserial /dev/ttyJ0
/dev/ttyJ0, UART: 16950/954, Port: 0xdc00, IRQ: 11
/dev # setserial /dev/ttyJ1

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

i know some AT Commands , i've got the whole AT Commands Set from nokia
i am using Windows XP-SP2
can anyone help me in a code or anything that .. 
sends an sms from the PC to customer , through the n6260 connected ??
and read sms and process the sm text , then respond to the customer again

i try AT+CMGS it works fine in HyperTerminal of Windows XP




any suggestions are welcome

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Subject: [Rxtx] Problem on Mac OS X
Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)
               {
                 System.out.println("Unsupported comm parameters: " +  
eUnsupported.getMessage());
               }
             }
             catch(TooManyListenersException eTooMany)
             {
               System.out.println("Too many listeners on comm port: "  
+ eTooMany.getMessage());
             }
           }
           catch(IOException eIO)
           {
             System.out.println("GPS port input stream exception: " +  
eIO.getMessage());
           }
         }
         catch(PortInUseException eInUse)
         {
           System.out.println("GPS port in use by another  
application: " + eInUse.getMessage());
         }

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

Hi,
My machine CPU is intel xscale ixp-422
and the OS is monta vista embedded linux 2.4.18.
and JVM  is CDC1.0.1 .
And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

Experimental:  JNI_OnLoad called.
Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
/dev/ttyS0
/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

[1] See "Q.  How does rxtx detect ports?  Can I override it?"
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7/INSTALL

Thanks a lot. 
I use the command:
cvm 
-Dgnu.io.rxtx.SerialPorts=/dev/ttyM0:/dev/ttyM1:/dev/ttyM2:/dev/ttyM3:/dev/ttyM4:/dev/ttyM5:/dev/ttyM6:/dev/ttyM7 
myapp

It can list ports what I want.
Now I 'll test the main I/O function for my device.

And, yes , I obtained the armv5b-softfloat-linux-gnu/librxtxSerial.so from 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

and I tried several version about arm or xscale but they
will throw an exception :
java.lang.UnsatisfiedLinkError: /root/cvm_rmi/lib/librxtxSerial.so


ps: Also thanks for your patience of my poor English.

what is this M0/M1 etc?

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
java.io.IOException: Underlying input stream returned zero bytes
	at sun.nio.cs.StreamDecoder$CharsetSD.readBytes(StreamDecoder.java:415)
	at sun.nio.cs.StreamDecoder$CharsetSD.implRead(StreamDecoder.java:453)

	at it.gps.Prova.<init>(Prova.java:24)
	at it.gps.Prova.main(Prova.java:48)

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Subject: [Rxtx] fixing rxtx configurations...you need to be root for this,

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!
  - Doug

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

Hi,

I just installed a PCI serial card (RS422/485). I loaded the linux
kernel module driver, made the /dev/ nodes, looks fine but RXTX see only
my /dev/ttyS0 & /dev/ttyS1 RS232 ports and not the new ones. 

dmesg extract :

"ttyJ1 at I/O 0xdc08 (irq = 11) is a 16C950/954"


Any idea ?

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

can anyone help me in a code or anything that .. 
sends an sms from the PC to customer , through the n6260 connected ??

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

> Would you share with us how you do the rs232/rs485 in hardware?

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Subject: [Rxtx] Problem on Mac OS X
Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)
               {
                 System.out.println("Unsupported comm parameters: " +  
eUnsupported.getMessage());
               }
             }
             catch(TooManyListenersException eTooMany)
             {
               System.out.println("Too many listeners on comm port: "  
+ eTooMany.getMessage());
             }
           }
           catch(IOException eIO)
           {
             System.out.println("GPS port input stream exception: " +  
eIO.getMessage());
           }
         }
         catch(PortInUseException eInUse)
         {
           System.out.println("GPS port in use by another  
application: " + eInUse.getMessage());
         }

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();
         return StringUtils.contains(s[0], "uucp") &&
                 StringUtils.contains(s[0], "lock");
     }


     public static String[] groups() {
         String command =
                 "groups ";
         try {
             return OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
         return null;
     }

     public static void print(Object o[]) {
         for (int i = 0; i < o.length; i++) {
             System.out.println(o[i]);
         }
     }

     public static void tarXvf(File f) {
         String command =
                 "tar " +
                         " -xf " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
     }

     public static void chmodPlusX(File f) {
         String command =
                 "chmod " +

                         f.getAbsolutePath();
         try {

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

Hi,
My machine CPU is intel xscale ixp-422
and the OS is monta vista embedded linux 2.4.18.
and JVM  is CDC1.0.1 .
And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

Experimental:  JNI_OnLoad called.
Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
/dev/ttyS0
/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

[1] See "Q.  How does rxtx detect ports?  Can I override it?"

and I tried several version about arm or xscale but they

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

                         CandidatePortPrefixes=Temp;
                 }

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
java.io.IOException: Underlying input stream returned zero bytes

	at it.gps.Prova.main(Prova.java:48)

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

Thanks,

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:

Any idea?

P.S. I'm using Matlab everyday at my university for my research

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Subject: [Rxtx] fixing rxtx configurations...you need to be root for this,

Message-ID: <p060204abc039f5331115@[192.168.1.152]>

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!
  - Doug

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

[1.1] It was fun...

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Very strange, it looks like real ports for me : 

/dev # setserial /dev/ttyJ0
/dev/ttyJ0, UART: 16950/954, Port: 0xdc00, IRQ: 11
/dev # setserial /dev/ttyJ1

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

i assume that the "Java" part of my project will be responsible of dealing with SMS.

i have a nokia 6260 phone , connected to my PC through Bluetooth (Virtual modem/serial port ) , i can connect my phone to PC also by using a DKU-2 cable

i know some AT Commands , i've got the whole AT Commands Set from nokia
i am using Windows XP-SP2
can anyone help me in a code or anything that .. 
sends an sms from the PC to customer , through the n6260 connected ??
and read sms and process the sm text , then respond to the customer again

i try AT+CMGS it works fine in HyperTerminal of Windows XP




any suggestions are welcome

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

Regards,
Thanasis.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

> Would you share with us how you do the rs232/rs485 in hardware?

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Subject: [Rxtx] Problem on Mac OS X
Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)
               {
                 System.out.println("Unsupported comm parameters: " +  
eUnsupported.getMessage());
               }
             }
             catch(TooManyListenersException eTooMany)
             {
               System.out.println("Too many listeners on comm port: "  
+ eTooMany.getMessage());
             }
           }
           catch(IOException eIO)
           {
             System.out.println("GPS port input stream exception: " +  
eIO.getMessage());
           }
         }
         catch(PortInUseException eInUse)
         {
           System.out.println("GPS port in use by another  
application: " + eInUse.getMessage());
         }

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();
         return StringUtils.contains(s[0], "uucp") &&
                 StringUtils.contains(s[0], "lock");
     }


     public static String[] groups() {
         String command =
                 "groups ";
         try {
             return OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
         return null;
     }

     public static void print(Object o[]) {
         for (int i = 0; i < o.length; i++) {
             System.out.println(o[i]);
         }
     }

     public static void tarXvf(File f) {
         String command =
                 "tar " +
                         " -xf " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
     }

     public static void chmodPlusX(File f) {
         String command =
                 "chmod " +

                         f.getAbsolutePath();

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

Hi,
My machine CPU is intel xscale ixp-422
and the OS is monta vista embedded linux 2.4.18.
and JVM  is CDC1.0.1 .
And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

Experimental:  JNI_OnLoad called.
Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
/dev/ttyS0
/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

[1] See "Q.  How does rxtx detect ports?  Can I override it?"
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7/INSTALL

Thanks a lot. 
I use the command:
cvm 
-Dgnu.io.rxtx.SerialPorts=/dev/ttyM0:/dev/ttyM1:/dev/ttyM2:/dev/ttyM3:/dev/ttyM4:/dev/ttyM5:/dev/ttyM6:/dev/ttyM7 
myapp

It can list ports what I want.
Now I 'll test the main I/O function for my device.

And, yes , I obtained the armv5b-softfloat-linux-gnu/librxtxSerial.so from 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

and I tried several version about arm or xscale but they
will throw an exception :
java.lang.UnsatisfiedLinkError: /root/cvm_rmi/lib/librxtxSerial.so


ps: Also thanks for your patience of my poor English.

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

                         CandidatePortPrefixes=Temp;
                 }

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
java.io.IOException: Underlying input stream returned zero bytes
	at sun.nio.cs.StreamDecoder$CharsetSD.readBytes(StreamDecoder.java:415)
	at sun.nio.cs.StreamDecoder$CharsetSD.implRead(StreamDecoder.java:453)

	at it.gps.Prova.<init>(Prova.java:24)
	at it.gps.Prova.main(Prova.java:48)

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.

However I don't understand why I must wait for 4 minute before obtain

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Message-ID: <p060204abc039f5331115@[192.168.1.152]>

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!
  - Doug

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

[1.1] It was fun...

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

Hi,

I just installed a PCI serial card (RS422/485). I loaded the linux
kernel module driver, made the /dev/ nodes, looks fine but RXTX see only
my /dev/ttyS0 & /dev/ttyS1 RS232 ports and not the new ones. 

dmesg extract :
"Found Korenix JetCard 1402"
"ttyJ0 at I/O 0xdc00 (irq = 11) is a 16C950/954"
"ttyJ1 at I/O 0xdc08 (irq = 11) is a 16C950/954"


Any idea ?

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Very strange, it looks like real ports for me : 

/dev # setserial /dev/ttyJ0
/dev/ttyJ0, UART: 16950/954, Port: 0xdc00, IRQ: 11
/dev # setserial /dev/ttyJ1
/dev/ttyJ1, UART: 16950/954, Port: 0xdc08, IRQ: 11

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

:)

i am developing an application which will use java & oracle & php

i assume that the "Java" part of my project will be responsible of dealing with SMS.

i have a nokia 6260 phone , connected to my PC through Bluetooth (Virtual modem/serial port ) , i can connect my phone to PC also by using a DKU-2 cable

i know some AT Commands , i've got the whole AT Commands Set from nokia
i am using Windows XP-SP2
can anyone help me in a code or anything that .. 
sends an sms from the PC to customer , through the n6260 connected ??
and read sms and process the sm text , then respond to the customer again

i try AT+CMGS it works fine in HyperTerminal of Windows XP




any suggestions are welcome

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

> Would you share with us how you do the rs232/rs485 in hardware?

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Subject: [Rxtx] Problem on Mac OS X
Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();
         return StringUtils.contains(s[0], "uucp") &&
                 StringUtils.contains(s[0], "lock");
     }


     public static String[] groups() {
         String command =
                 "groups ";
         try {
             return OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
         return null;
     }

     public static void print(Object o[]) {
         for (int i = 0; i < o.length; i++) {
             System.out.println(o[i]);
         }
     }

     public static void tarXvf(File f) {
         String command =
                 "tar " +
                         " -xf " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
     }

     public static void chmodPlusX(File f) {
         String command =
                 "chmod " +
                         " +x " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

and the OS is monta vista embedded linux 2.4.18.
and JVM  is CDC1.0.1 .
And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

Experimental:  JNI_OnLoad called.

=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
/dev/ttyS0
/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

[1] See "Q.  How does rxtx detect ports?  Can I override it?"
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7/INSTALL

Thanks a lot.

It can list ports what I want.
Now I 'll test the main I/O function for my device.

And, yes , I obtained the armv5b-softfloat-linux-gnu/librxtxSerial.so from 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

and I tried several version about arm or xscale but they
will throw an exception :
java.lang.UnsatisfiedLinkError: /root/cvm_rmi/lib/librxtxSerial.so


ps: Also thanks for your patience of my poor English.

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
java.io.IOException: Underlying input stream returned zero bytes
	at sun.nio.cs.StreamDecoder$CharsetSD.readBytes(StreamDecoder.java:415)
	at sun.nio.cs.StreamDecoder$CharsetSD.implRead(StreamDecoder.java:453)
	at sun.nio.cs.StreamDecoder.read(StreamDecoder.java:183)
	at java.io.InputStreamReader.read(InputStreamReader.java:167)
	at java.io.BufferedReader.fill(BufferedReader.java:136)
	at java.io.BufferedReader.readLine(BufferedReader.java:299)
	at java.io.BufferedReader.readLine(BufferedReader.java:362)
	at cz.darmovzalt.gps.Nmea.process(Nmea.java:89)
	at it.gps.Prova.<init>(Prova.java:24)
	at it.gps.Prova.main(Prova.java:48)

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

Thanks,

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Subject: [Rxtx] fixing rxtx configurations...you need to be root for this,

Message-ID: <p060204abc039f5331115@[192.168.1.152]>

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!
  - Doug

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

My machine is MOXA  which has 8 serial port look like rj45 port. I must use 
a connector to transfer serial to rj45.

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

Hi,
Because I will remote control the machine which connect the rs232 device . 
So , I have a problem , I don't know that is the rs232 device connect to 
the machine. Maybe the device is turn off , or someone pull out the line. I 
should know
the device connection status.

How should I do?

Hi,

I just installed a PCI serial card (RS422/485). I loaded the linux
kernel module driver, made the /dev/ nodes, looks fine but RXTX see only
my /dev/ttyS0 & /dev/ttyS1 RS232 ports and not the new ones. 

dmesg extract :
"Found Korenix JetCard 1402"
"ttyJ0 at I/O 0xdc00 (irq = 11) is a 16C950/954"
"ttyJ1 at I/O 0xdc08 (irq = 11) is a 16C950/954"


Any idea ?

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

> Would you share with us how you do the rs232/rs485 in hardware?

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Subject: [Rxtx] Problem on Mac OS X
Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)
               {
                 System.out.println("Unsupported comm parameters: " +  
eUnsupported.getMessage());
               }
             }
             catch(TooManyListenersException eTooMany)
             {
               System.out.println("Too many listeners on comm port: "  
+ eTooMany.getMessage());
             }
           }
           catch(IOException eIO)
           {
             System.out.println("GPS port input stream exception: " +  
eIO.getMessage());
           }
         }
         catch(PortInUseException eInUse)
         {
           System.out.println("GPS port in use by another  
application: " + eInUse.getMessage());
         }

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();
         return StringUtils.contains(s[0], "uucp") &&
                 StringUtils.contains(s[0], "lock");
     }


     public static String[] groups() {
         String command =
                 "groups ";
         try {
             return OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
         return null;
     }

     public static void print(Object o[]) {
         for (int i = 0; i < o.length; i++) {
             System.out.println(o[i]);
         }
     }

     public static void tarXvf(File f) {
         String command =
                 "tar " +
                         " -xf " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
     }

     public static void chmodPlusX(File f) {
         String command =
                 "chmod " +
                         " +x " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

Thanks a lot. 
I use the command:
cvm 
-Dgnu.io.rxtx.SerialPorts=/dev/ttyM0:/dev/ttyM1:/dev/ttyM2:/dev/ttyM3:/dev/ttyM4:/dev/ttyM5:/dev/ttyM6:/dev/ttyM7 
myapp

It can list ports what I want.
Now I 'll test the main I/O function for my device.

And, yes , I obtained the armv5b-softfloat-linux-gnu/librxtxSerial.so from 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

and I tried several version about arm or xscale but they
will throw an exception :
java.lang.UnsatisfiedLinkError: /root/cvm_rmi/lib/librxtxSerial.so


ps: Also thanks for your patience of my poor English.

Excuse me sir
i thought that the serial ports on linux are /dev/ttyS0 or /dev/tty/S1 etc.
what is this M0/M1 etc?

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

                         CandidatePortPrefixes=Temp;
                 }

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:
:
$GPGSV,3,2,09,14,36,105,00,01,20,148,00,28,11,322,00,20,09,223,00*7A

Any idea?

P.S. I'm using Matlab everyday at my university for my research
activity. Good luck, Trent!!!

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Subject: [Rxtx] fixing rxtx configurations...you need to be root for this,

Message-ID: <p060204abc039f5331115@[192.168.1.152]>

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!
  - Doug

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

[1.1] It was fun...

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

Any idea ?

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Very strange, it looks like real ports for me : 

/dev # setserial /dev/ttyJ0
/dev/ttyJ0, UART: 16950/954, Port: 0xdc00, IRQ: 11
/dev # setserial /dev/ttyJ1

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

:)

i assume that the "Java" part of my project will be responsible of dealing with SMS.

i have a nokia 6260 phone , connected to my PC through Bluetooth (Virtual modem/serial port ) , i can connect my phone to PC also by using a DKU-2 cable

i know some AT Commands , i've got the whole AT Commands Set from nokia
i am using Windows XP-SP2
can anyone help me in a code or anything that .. 
sends an sms from the PC to customer , through the n6260 connected ??
and read sms and process the sm text , then respond to the customer again

i try AT+CMGS it works fine in HyperTerminal of Windows XP




any suggestions are welcome

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Subject: [Rxtx] Problem on Mac OS X
Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)
               {
                 System.out.println("Unsupported comm parameters: " +  
eUnsupported.getMessage());
               }
             }
             catch(TooManyListenersException eTooMany)
             {
               System.out.println("Too many listeners on comm port: "  
+ eTooMany.getMessage());
             }
           }
           catch(IOException eIO)
           {
             System.out.println("GPS port input stream exception: " +  
eIO.getMessage());
           }
         }
         catch(PortInUseException eInUse)
         {
           System.out.println("GPS port in use by another  
application: " + eInUse.getMessage());
         }

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();

Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {

                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

Hi,
My machine CPU is intel xscale ixp-422
and the OS is monta vista embedded linux 2.4.18.
and JVM  is CDC1.0.1 .
And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

Experimental:  JNI_OnLoad called.
Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
/dev/ttyS0
/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

[1] See "Q.  How does rxtx detect ports?  Can I override it?"
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7/INSTALL

Thanks a lot. 
I use the command:
cvm 
-Dgnu.io.rxtx.SerialPorts=/dev/ttyM0:/dev/ttyM1:/dev/ttyM2:/dev/ttyM3:/dev/ttyM4:/dev/ttyM5:/dev/ttyM6:/dev/ttyM7 
myapp

It can list ports what I want.
Now I 'll test the main I/O function for my device.

And, yes , I obtained the armv5b-softfloat-linux-gnu/librxtxSerial.so from 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

and I tried several version about arm or xscale but they
will throw an exception :
java.lang.UnsatisfiedLinkError: /root/cvm_rmi/lib/librxtxSerial.so


ps: Also thanks for your patience of my poor English.

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

                         CandidatePortPrefixes=Temp;

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
java.io.IOException: Underlying input stream returned zero bytes
	at sun.nio.cs.StreamDecoder$CharsetSD.readBytes(StreamDecoder.java:415)

	at it.gps.Prova.<init>(Prova.java:24)
	at it.gps.Prova.main(Prova.java:48)

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Subject: [Rxtx] fixing rxtx configurations...you need to be root for this,

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!
  - Doug

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

Hi,

I just installed a PCI serial card (RS422/485). I loaded the linux

my /dev/ttyS0 & /dev/ttyS1 RS232 ports and not the new ones. 

dmesg extract :

"ttyJ1 at I/O 0xdc08 (irq = 11) is a 16C950/954"


Any idea ?

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

can anyone help me in a code or anything that .. 
sends an sms from the PC to customer , through the n6260 connected ??
and read sms and process the sm text , then respond to the customer again

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

> Would you share with us how you do the rs232/rs485 in hardware?

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Subject: [Rxtx] Problem on Mac OS X
Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)
               {
                 System.out.println("Unsupported comm parameters: " +  
eUnsupported.getMessage());
               }
             }
             catch(TooManyListenersException eTooMany)
             {
               System.out.println("Too many listeners on comm port: "  
+ eTooMany.getMessage());
             }
           }
           catch(IOException eIO)
           {
             System.out.println("GPS port input stream exception: " +  
eIO.getMessage());
           }
         }
         catch(PortInUseException eInUse)
         {
           System.out.println("GPS port in use by another  
application: " + eInUse.getMessage());
         }

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();
         return StringUtils.contains(s[0], "uucp") &&
                 StringUtils.contains(s[0], "lock");
     }


     public static String[] groups() {
         String command =
                 "groups ";
         try {
             return OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
         return null;
     }

     public static void print(Object o[]) {
         for (int i = 0; i < o.length; i++) {
             System.out.println(o[i]);
         }
     }

     public static void tarXvf(File f) {
         String command =
                 "tar " +
                         " -xf " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
     }

     public static void chmodPlusX(File f) {

                         f.getAbsolutePath();
         try {

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

Hi,
My machine CPU is intel xscale ixp-422
and the OS is monta vista embedded linux 2.4.18.
and JVM  is CDC1.0.1 .
And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

Experimental:  JNI_OnLoad called.
Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
/dev/ttyS0
/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

[1] See "Q.  How does rxtx detect ports?  Can I override it?"

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

                         CandidatePortPrefixes=Temp;
                 }

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7

	at it.gps.Prova.main(Prova.java:48)

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

Thanks,

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:
:

P.S. I'm using Matlab everyday at my university for my research

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Subject: [Rxtx] fixing rxtx configurations...you need to be root for this,

Message-ID: <p060204abc039f5331115@[192.168.1.152]>

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!
  - Doug

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

[1.1] It was fun...

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

Did you change the import line in your .java file?

Nice to see another Italian here :-D

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Very strange, it looks like real ports for me : 

/dev # setserial /dev/ttyJ0
/dev/ttyJ0, UART: 16950/954, Port: 0xdc00, IRQ: 11
/dev # setserial /dev/ttyJ1

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

:)

hi everybody 

i am a new to serial programming ...
i am a senior IT student , i will graduate by the end of this semister
i am developing an application which will use java & oracle & php

i assume that the "Java" part of my project will be responsible of dealing with SMS.

i have a nokia 6260 phone , connected to my PC through Bluetooth (Virtual modem/serial port ) , i can connect my phone to PC also by using a DKU-2 cable

i know some AT Commands , i've got the whole AT Commands Set from nokia
i am using Windows XP-SP2
can anyone help me in a code or anything that .. 
sends an sms from the PC to customer , through the n6260 connected ??
and read sms and process the sm text , then respond to the customer again

i try AT+CMGS it works fine in HyperTerminal of Windows XP




any suggestions are welcome

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

Regards,
Thanasis.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

> Would you share with us how you do the rs232/rs485 in hardware?

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Subject: [Rxtx] Problem on Mac OS X
Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)
               {
                 System.out.println("Unsupported comm parameters: " +  
eUnsupported.getMessage());
               }
             }
             catch(TooManyListenersException eTooMany)
             {
               System.out.println("Too many listeners on comm port: "  
+ eTooMany.getMessage());
             }
           }
           catch(IOException eIO)
           {
             System.out.println("GPS port input stream exception: " +  
eIO.getMessage());
           }
         }
         catch(PortInUseException eInUse)
         {
           System.out.println("GPS port in use by another  
application: " + eInUse.getMessage());
         }

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();
         return StringUtils.contains(s[0], "uucp") &&
                 StringUtils.contains(s[0], "lock");
     }


     public static String[] groups() {
         String command =
                 "groups ";
         try {
             return OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
         return null;
     }

     public static void print(Object o[]) {
         for (int i = 0; i < o.length; i++) {
             System.out.println(o[i]);
         }
     }

     public static void tarXvf(File f) {
         String command =
                 "tar " +
                         " -xf " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
     }

     public static void chmodPlusX(File f) {
         String command =
                 "chmod " +
                         " +x " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

and the OS is monta vista embedded linux 2.4.18.
and JVM  is CDC1.0.1 .
And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

Experimental:  JNI_OnLoad called.
Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
/dev/ttyS0
/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

[1] See "Q.  How does rxtx detect ports?  Can I override it?"
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7/INSTALL

Thanks a lot. 
I use the command:
cvm 
-Dgnu.io.rxtx.SerialPorts=/dev/ttyM0:/dev/ttyM1:/dev/ttyM2:/dev/ttyM3:/dev/ttyM4:/dev/ttyM5:/dev/ttyM6:/dev/ttyM7 
myapp

It can list ports what I want.
Now I 'll test the main I/O function for my device.

And, yes , I obtained the armv5b-softfloat-linux-gnu/librxtxSerial.so from 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

and I tried several version about arm or xscale but they
will throw an exception :
java.lang.UnsatisfiedLinkError: /root/cvm_rmi/lib/librxtxSerial.so


ps: Also thanks for your patience of my poor English.

Excuse me sir
i thought that the serial ports on linux are /dev/ttyS0 or /dev/tty/S1 etc.
what is this M0/M1 etc?
PLEASER CLARIFY

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

                 }

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
java.io.IOException: Underlying input stream returned zero bytes

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Message-ID: <p060204abc039f5331115@[192.168.1.152]>

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!
  - Doug

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

[1.1] It was fun...

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

Hi,

I just installed a PCI serial card (RS422/485). I loaded the linux
kernel module driver, made the /dev/ nodes, looks fine but RXTX see only
my /dev/ttyS0 & /dev/ttyS1 RS232 ports and not the new ones. 

dmesg extract :
"Found Korenix JetCard 1402"
"ttyJ0 at I/O 0xdc00 (irq = 11) is a 16C950/954"
"ttyJ1 at I/O 0xdc08 (irq = 11) is a 16C950/954"


Any idea ?

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Very strange, it looks like real ports for me : 

/dev # setserial /dev/ttyJ0
/dev/ttyJ0, UART: 16950/954, Port: 0xdc00, IRQ: 11
/dev # setserial /dev/ttyJ1
/dev/ttyJ1, UART: 16950/954, Port: 0xdc08, IRQ: 11

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

i am developing an application which will use java & oracle & php

i assume that the "Java" part of my project will be responsible of dealing with SMS.

i have a nokia 6260 phone , connected to my PC through Bluetooth (Virtual modem/serial port ) , i can connect my phone to PC also by using a DKU-2 cable

i know some AT Commands , i've got the whole AT Commands Set from nokia
i am using Windows XP-SP2
can anyone help me in a code or anything that .. 
sends an sms from the PC to customer , through the n6260 connected ??
and read sms and process the sm text , then respond to the customer again

i try AT+CMGS it works fine in HyperTerminal of Windows XP




any suggestions are welcome

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

> Would you share with us how you do the rs232/rs485 in hardware?

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Subject: [Rxtx] Problem on Mac OS X
Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();
         return StringUtils.contains(s[0], "uucp") &&
                 StringUtils.contains(s[0], "lock");
     }


     public static String[] groups() {
         String command =
                 "groups ";
         try {
             return OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
         return null;
     }

     public static void print(Object o[]) {
         for (int i = 0; i < o.length; i++) {
             System.out.println(o[i]);
         }
     }

     public static void tarXvf(File f) {
         String command =
                 "tar " +
                         " -xf " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
     }

     public static void chmodPlusX(File f) {
         String command =
                 "chmod " +
                         " +x " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
     }
}

public class OsUtils {

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

Hi,
My machine CPU is intel xscale ixp-422
and the OS is monta vista embedded linux 2.4.18.
and JVM  is CDC1.0.1 .
And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

Experimental:  JNI_OnLoad called.
Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
/dev/ttyS0
/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

[1] See "Q.  How does rxtx detect ports?  Can I override it?"
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7/INSTALL

Thanks a lot. 
I use the command:
cvm 
-Dgnu.io.rxtx.SerialPorts=/dev/ttyM0:/dev/ttyM1:/dev/ttyM2:/dev/ttyM3:/dev/ttyM4:/dev/ttyM5:/dev/ttyM6:/dev/ttyM7

It can list ports what I want.
Now I 'll test the main I/O function for my device.

And, yes , I obtained the armv5b-softfloat-linux-gnu/librxtxSerial.so from 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

and I tried several version about arm or xscale but they
will throw an exception :
java.lang.UnsatisfiedLinkError: /root/cvm_rmi/lib/librxtxSerial.so


ps: Also thanks for your patience of my poor English.

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
java.io.IOException: Underlying input stream returned zero bytes
	at sun.nio.cs.StreamDecoder$CharsetSD.readBytes(StreamDecoder.java:415)
	at sun.nio.cs.StreamDecoder$CharsetSD.implRead(StreamDecoder.java:453)
	at sun.nio.cs.StreamDecoder.read(StreamDecoder.java:183)
	at java.io.InputStreamReader.read(InputStreamReader.java:167)
	at java.io.BufferedReader.fill(BufferedReader.java:136)
	at java.io.BufferedReader.readLine(BufferedReader.java:299)
	at java.io.BufferedReader.readLine(BufferedReader.java:362)
	at cz.darmovzalt.gps.Nmea.process(Nmea.java:89)
	at it.gps.Prova.<init>(Prova.java:24)
	at it.gps.Prova.main(Prova.java:48)

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

Thanks,

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Subject: [Rxtx] fixing rxtx configurations...you need to be root for this,

Message-ID: <p060204abc039f5331115@[192.168.1.152]>

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!
  - Doug

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

[1.1] It was fun...

My machine is MOXA  which has 8 serial port look like rj45 port. I must use 
a connector to transfer serial to rj45.

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

Hi,
Because I will remote control the machine which connect the rs232 device . 
So , I have a problem , I don't know that is the rs232 device connect to

How should I do?

Hi,

I just installed a PCI serial card (RS422/485). I loaded the linux
kernel module driver, made the /dev/ nodes, looks fine but RXTX see only
my /dev/ttyS0 & /dev/ttyS1 RS232 ports and not the new ones. 

dmesg extract :

"ttyJ0 at I/O 0xdc00 (irq = 11) is a 16C950/954"
"ttyJ1 at I/O 0xdc08 (irq = 11) is a 16C950/954"


Any idea ?

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

> Would you share with us how you do the rs232/rs485 in hardware?

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Subject: [Rxtx] Problem on Mac OS X
Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)
               {
                 System.out.println("Unsupported comm parameters: " +  
eUnsupported.getMessage());
               }
             }
             catch(TooManyListenersException eTooMany)
             {
               System.out.println("Too many listeners on comm port: "  
+ eTooMany.getMessage());
             }
           }
           catch(IOException eIO)
           {
             System.out.println("GPS port input stream exception: " +  
eIO.getMessage());
           }
         }
         catch(PortInUseException eInUse)
         {
           System.out.println("GPS port in use by another  
application: " + eInUse.getMessage());
         }

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();
         return StringUtils.contains(s[0], "uucp") &&
                 StringUtils.contains(s[0], "lock");
     }


     public static String[] groups() {
         String command =
                 "groups ";
         try {
             return OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
         return null;
     }

     public static void print(Object o[]) {
         for (int i = 0; i < o.length; i++) {
             System.out.println(o[i]);
         }
     }

     public static void tarXvf(File f) {
         String command =
                 "tar " +
                         " -xf " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
     }

     public static void chmodPlusX(File f) {
         String command =
                 "chmod " +
                         " +x " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

Hi,
My machine CPU is intel xscale ixp-422
and the OS is monta vista embedded linux 2.4.18.
and JVM  is CDC1.0.1 .
And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

Experimental:  JNI_OnLoad called.
Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
/dev/ttyS0
/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

Thanks a lot. 
I use the command:
cvm 
-Dgnu.io.rxtx.SerialPorts=/dev/ttyM0:/dev/ttyM1:/dev/ttyM2:/dev/ttyM3:/dev/ttyM4:/dev/ttyM5:/dev/ttyM6:/dev/ttyM7 
myapp

It can list ports what I want.
Now I 'll test the main I/O function for my device.

And, yes , I obtained the armv5b-softfloat-linux-gnu/librxtxSerial.so from 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

and I tried several version about arm or xscale but they
will throw an exception :
java.lang.UnsatisfiedLinkError: /root/cvm_rmi/lib/librxtxSerial.so


ps: Also thanks for your patience of my poor English.

Excuse me sir
i thought that the serial ports on linux are /dev/ttyS0 or /dev/tty/S1 etc.
what is this M0/M1 etc?

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

                         CandidatePortPrefixes=Temp;
                 }

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:
:

Any idea?

P.S. I'm using Matlab everyday at my university for my research
activity. Good luck, Trent!!!

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Subject: [Rxtx] fixing rxtx configurations...you need to be root for this,
	right?
Message-ID: <p060204abc039f5331115@[192.168.1.152]>

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!
  - Doug

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

[1.1] It was fun...

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Very strange, it looks like real ports for me : 

/dev # setserial /dev/ttyJ0
/dev/ttyJ0, UART: 16950/954, Port: 0xdc00, IRQ: 11
/dev # setserial /dev/ttyJ1
/dev/ttyJ1, UART: 16950/954, Port: 0xdc08, IRQ: 11

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

:)

i know some AT Commands , i've got the whole AT Commands Set from nokia
i am using Windows XP-SP2
can anyone help me in a code or anything that .. 
sends an sms from the PC to customer , through the n6260 connected ??
and read sms and process the sm text , then respond to the customer again

i try AT+CMGS it works fine in HyperTerminal of Windows XP




any suggestions are welcome

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)
               {
                 System.out.println("Unsupported comm parameters: " +  
eUnsupported.getMessage());
               }
             }
             catch(TooManyListenersException eTooMany)
             {
               System.out.println("Too many listeners on comm port: "  
+ eTooMany.getMessage());
             }
           }
           catch(IOException eIO)
           {
             System.out.println("GPS port input stream exception: " +  
eIO.getMessage());
           }
         }
         catch(PortInUseException eInUse)
         {
           System.out.println("GPS port in use by another  
application: " + eInUse.getMessage());
         }

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

Hi,
My machine CPU is intel xscale ixp-422
and the OS is monta vista embedded linux 2.4.18.
and JVM  is CDC1.0.1 .
And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

Experimental:  JNI_OnLoad called.
Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
/dev/ttyS0
/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

[1] See "Q.  How does rxtx detect ports?  Can I override it?"
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7/INSTALL

Thanks a lot. 
I use the command:
cvm 
-Dgnu.io.rxtx.SerialPorts=/dev/ttyM0:/dev/ttyM1:/dev/ttyM2:/dev/ttyM3:/dev/ttyM4:/dev/ttyM5:/dev/ttyM6:/dev/ttyM7 
myapp

It can list ports what I want.
Now I 'll test the main I/O function for my device.

And, yes , I obtained the armv5b-softfloat-linux-gnu/librxtxSerial.so from 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

and I tried several version about arm or xscale but they
will throw an exception :
java.lang.UnsatisfiedLinkError: /root/cvm_rmi/lib/librxtxSerial.so


ps: Also thanks for your patience of my poor English.

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
java.io.IOException: Underlying input stream returned zero bytes

	at it.gps.Prova.<init>(Prova.java:24)
	at it.gps.Prova.main(Prova.java:48)

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Message-ID: <p060204abc039f5331115@[192.168.1.152]>

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!
  - Doug

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

I just installed a PCI serial card (RS422/485). I loaded the linux

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

Subject: [Rxtx] Linux, installed an extra PCI serial port card, but
	RXTX see	nothing

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

> Would you share with us how you do the rs232/rs485 in hardware?

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Subject: [Rxtx] Problem on Mac OS X
Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)
               {
                 System.out.println("Unsupported comm parameters: " +  
eUnsupported.getMessage());
               }
             }

             {
               System.out.println("Too many listeners on comm port: "

             }
           }
           catch(IOException eIO)
           {
             System.out.println("GPS port input stream exception: " +  
eIO.getMessage());
           }
         }
         catch(PortInUseException eInUse)
         {
           System.out.println("GPS port in use by another  
application: " + eInUse.getMessage());
         }

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();
         return StringUtils.contains(s[0], "uucp") &&
                 StringUtils.contains(s[0], "lock");
     }


     public static String[] groups() {
         String command =
                 "groups ";
         try {
             return OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
         return null;
     }

     public static void print(Object o[]) {
         for (int i = 0; i < o.length; i++) {
             System.out.println(o[i]);
         }
     }

     public static void tarXvf(File f) {
         String command =
                 "tar " +
                         " -xf " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();

                         f.getAbsolutePath();

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

Hi,
My machine CPU is intel xscale ixp-422
and the OS is monta vista embedded linux 2.4.18.
and JVM  is CDC1.0.1 .
And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

Experimental:  JNI_OnLoad called.
Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
/dev/ttyS0
/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

[1] See "Q.  How does rxtx detect ports?  Can I override it?"

and I tried several version about arm or xscale but they

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

                         CandidatePortPrefixes=Temp;
                 }

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

Stable Library

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:

P.S. I'm using Matlab everyday at my university for my research

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Subject: [Rxtx] fixing rxtx configurations...you need to be root for this,

Message-ID: <p060204abc039f5331115@[192.168.1.152]>

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!
  - Doug

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

[1.1] It was fun...

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

So , I have a problem , I don't know that is the rs232 device connect to 
the machine. Maybe the device is turn off , or someone pull out the line. I 
should know
the device connection status.

How should I do?

thanks.

Hi,

I just installed a PCI serial card (RS422/485). I loaded the linux
kernel module driver, made the /dev/ nodes, looks fine but RXTX see only
my /dev/ttyS0 & /dev/ttyS1 RS232 ports and not the new ones. 

dmesg extract :
"Found Korenix JetCard 1402"
"ttyJ0 at I/O 0xdc00 (irq = 11) is a 16C950/954"
"ttyJ1 at I/O 0xdc08 (irq = 11) is a 16C950/954"


Any idea ?

Juilen

Did you change the import line in your .java file?

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Very strange, it looks like real ports for me : 

/dev # setserial /dev/ttyJ0
/dev/ttyJ0, UART: 16950/954, Port: 0xdc00, IRQ: 11
/dev # setserial /dev/ttyJ1

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

:)

i assume that the "Java" part of my project will be responsible of dealing with SMS.

i have a nokia 6260 phone , connected to my PC through Bluetooth (Virtual modem/serial port ) , i can connect my phone to PC also by using a DKU-2 cable

i know some AT Commands , i've got the whole AT Commands Set from nokia
i am using Windows XP-SP2
can anyone help me in a code or anything that .. 
sends an sms from the PC to customer , through the n6260 connected ??
and read sms and process the sm text , then respond to the customer again

i try AT+CMGS it works fine in HyperTerminal of Windows XP




any suggestions are welcome

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

Thanasis.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

> Would you share with us how you do the rs232/rs485 in hardware?

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Subject: [Rxtx] Problem on Mac OS X
Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)
               {
                 System.out.println("Unsupported comm parameters: " +  
eUnsupported.getMessage());
               }
             }
             catch(TooManyListenersException eTooMany)
             {
               System.out.println("Too many listeners on comm port: "  
+ eTooMany.getMessage());
             }
           }
           catch(IOException eIO)
           {
             System.out.println("GPS port input stream exception: " +  
eIO.getMessage());
           }
         }
         catch(PortInUseException eInUse)
         {
           System.out.println("GPS port in use by another  
application: " + eInUse.getMessage());
         }

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();
         return StringUtils.contains(s[0], "uucp") &&
                 StringUtils.contains(s[0], "lock");
     }


     public static String[] groups() {
         String command =
                 "groups ";
         try {
             return OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
         return null;
     }

     public static void print(Object o[]) {
         for (int i = 0; i < o.length; i++) {
             System.out.println(o[i]);
         }
     }

     public static void tarXvf(File f) {
         String command =
                 "tar " +
                         " -xf " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
     }

     public static void chmodPlusX(File f) {
         String command =
                 "chmod " +
                         " +x " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
/dev/ttyS0
/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

[1] See "Q.  How does rxtx detect ports?  Can I override it?"
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7/INSTALL

Thanks a lot. 
I use the command:
cvm 
-Dgnu.io.rxtx.SerialPorts=/dev/ttyM0:/dev/ttyM1:/dev/ttyM2:/dev/ttyM3:/dev/ttyM4:/dev/ttyM5:/dev/ttyM6:/dev/ttyM7 
myapp

It can list ports what I want.
Now I 'll test the main I/O function for my device.

And, yes , I obtained the armv5b-softfloat-linux-gnu/librxtxSerial.so from 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

and I tried several version about arm or xscale but they
will throw an exception :
java.lang.UnsatisfiedLinkError: /root/cvm_rmi/lib/librxtxSerial.so


ps: Also thanks for your patience of my poor English.

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

                 }

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
java.io.IOException: Underlying input stream returned zero bytes

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Subject: [Rxtx] fixing rxtx configurations...you need to be root for this,
	right?
Message-ID: <p060204abc039f5331115@[192.168.1.152]>

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!
  - Doug

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

[1.1] It was fun...

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

Hi,

I just installed a PCI serial card (RS422/485). I loaded the linux
kernel module driver, made the /dev/ nodes, looks fine but RXTX see only
my /dev/ttyS0 & /dev/ttyS1 RS232 ports and not the new ones. 

dmesg extract :

"ttyJ1 at I/O 0xdc08 (irq = 11) is a 16C950/954"


Any idea ?

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Very strange, it looks like real ports for me : 

/dev # setserial /dev/ttyJ0
/dev/ttyJ0, UART: 16950/954, Port: 0xdc00, IRQ: 11
/dev # setserial /dev/ttyJ1
/dev/ttyJ1, UART: 16950/954, Port: 0xdc08, IRQ: 11

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

i am developing an application which will use java & oracle & php

i assume that the "Java" part of my project will be responsible of dealing with SMS.

i have a nokia 6260 phone , connected to my PC through Bluetooth (Virtual modem/serial port ) , i can connect my phone to PC also by using a DKU-2 cable

i know some AT Commands , i've got the whole AT Commands Set from nokia
i am using Windows XP-SP2
can anyone help me in a code or anything that .. 
sends an sms from the PC to customer , through the n6260 connected ??
and read sms and process the sm text , then respond to the customer again

i try AT+CMGS it works fine in HyperTerminal of Windows XP




any suggestions are welcome

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

> Would you share with us how you do the rs232/rs485 in hardware?

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Subject: [Rxtx] Problem on Mac OS X
Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();
         return StringUtils.contains(s[0], "uucp") &&
                 StringUtils.contains(s[0], "lock");
     }


     public static String[] groups() {
         String command =
                 "groups ";
         try {
             return OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
         return null;
     }

     public static void print(Object o[]) {
         for (int i = 0; i < o.length; i++) {
             System.out.println(o[i]);
         }
     }

     public static void tarXvf(File f) {
         String command =
                 "tar " +
                         " -xf " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
     }

     public static void chmodPlusX(File f) {
         String command =
                 "chmod " +
                         " +x " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
     }
}

With:
public class OsUtils {
     /**

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

Hi,
My machine CPU is intel xscale ixp-422
and the OS is monta vista embedded linux 2.4.18.
and JVM  is CDC1.0.1 .
And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

Experimental:  JNI_OnLoad called.
Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
/dev/ttyS0
/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

[1] See "Q.  How does rxtx detect ports?  Can I override it?"
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7/INSTALL

Thanks a lot. 
I use the command:

It can list ports what I want.
Now I 'll test the main I/O function for my device.

And, yes , I obtained the armv5b-softfloat-linux-gnu/librxtxSerial.so from 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

and I tried several version about arm or xscale but they
will throw an exception :
java.lang.UnsatisfiedLinkError: /root/cvm_rmi/lib/librxtxSerial.so


ps: Also thanks for your patience of my poor English.

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
java.io.IOException: Underlying input stream returned zero bytes
	at sun.nio.cs.StreamDecoder$CharsetSD.readBytes(StreamDecoder.java:415)
	at sun.nio.cs.StreamDecoder$CharsetSD.implRead(StreamDecoder.java:453)
	at sun.nio.cs.StreamDecoder.read(StreamDecoder.java:183)
	at java.io.InputStreamReader.read(InputStreamReader.java:167)
	at java.io.BufferedReader.fill(BufferedReader.java:136)
	at java.io.BufferedReader.readLine(BufferedReader.java:299)
	at java.io.BufferedReader.readLine(BufferedReader.java:362)
	at cz.darmovzalt.gps.Nmea.process(Nmea.java:89)
	at it.gps.Prova.<init>(Prova.java:24)
	at it.gps.Prova.main(Prova.java:48)

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Subject: [Rxtx] fixing rxtx configurations...you need to be root for this,
	right?
Message-ID: <p060204abc039f5331115@[192.168.1.152]>

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

Hi,

Hi,

I just installed a PCI serial card (RS422/485). I loaded the linux
kernel module driver, made the /dev/ nodes, looks fine but RXTX see only
my /dev/ttyS0 & /dev/ttyS1 RS232 ports and not the new ones. 

dmesg extract :

"ttyJ0 at I/O 0xdc00 (irq = 11) is a 16C950/954"
"ttyJ1 at I/O 0xdc08 (irq = 11) is a 16C950/954"


Any idea ?

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

> Would you share with us how you do the rs232/rs485 in hardware?

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Subject: [Rxtx] Problem on Mac OS X
Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)
               {
                 System.out.println("Unsupported comm parameters: " +  
eUnsupported.getMessage());
               }
             }
             catch(TooManyListenersException eTooMany)
             {
               System.out.println("Too many listeners on comm port: "  
+ eTooMany.getMessage());
             }
           }
           catch(IOException eIO)
           {
             System.out.println("GPS port input stream exception: " +  
eIO.getMessage());
           }
         }
         catch(PortInUseException eInUse)
         {
           System.out.println("GPS port in use by another  
application: " + eInUse.getMessage());
         }

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();
         return StringUtils.contains(s[0], "uucp") &&
                 StringUtils.contains(s[0], "lock");
     }


     public static String[] groups() {
         String command =
                 "groups ";
         try {
             return OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
         return null;
     }

     public static void print(Object o[]) {
         for (int i = 0; i < o.length; i++) {
             System.out.println(o[i]);
         }
     }

     public static void tarXvf(File f) {
         String command =
                 "tar " +
                         " -xf " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
     }

     public static void chmodPlusX(File f) {
         String command =
                 "chmod " +
                         " +x " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

I can't find the port what I want!!!
I tried to list all the port as below.

Experimental:  JNI_OnLoad called.
Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
/dev/ttyS0
/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

Thanks a lot. 
I use the command:

It can list ports what I want.
Now I 'll test the main I/O function for my device.

And, yes , I obtained the armv5b-softfloat-linux-gnu/librxtxSerial.so from 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

and I tried several version about arm or xscale but they
will throw an exception :
java.lang.UnsatisfiedLinkError: /root/cvm_rmi/lib/librxtxSerial.so


ps: Also thanks for your patience of my poor English.

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

                         CandidatePortPrefixes=Temp;
                 }

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:

Any idea?

P.S. I'm using Matlab everyday at my university for my research
activity. Good luck, Trent!!!

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Subject: [Rxtx] fixing rxtx configurations...you need to be root for this,
	right?
Message-ID: <p060204abc039f5331115@[192.168.1.152]>

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!
  - Doug

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

[1.1] It was fun...

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Very strange, it looks like real ports for me : 

/dev # setserial /dev/ttyJ0
/dev/ttyJ0, UART: 16950/954, Port: 0xdc00, IRQ: 11
/dev # setserial /dev/ttyJ1

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

:)

i know some AT Commands , i've got the whole AT Commands Set from nokia
i am using Windows XP-SP2
can anyone help me in a code or anything that .. 
sends an sms from the PC to customer , through the n6260 connected ??
and read sms and process the sm text , then respond to the customer again

i try AT+CMGS it works fine in HyperTerminal of Windows XP




any suggestions are welcome

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)
               {
                 System.out.println("Unsupported comm parameters: " +  
eUnsupported.getMessage());
               }
             }
             catch(TooManyListenersException eTooMany)
             {
               System.out.println("Too many listeners on comm port: "  
+ eTooMany.getMessage());
             }
           }
           catch(IOException eIO)
           {
             System.out.println("GPS port input stream exception: " +  
eIO.getMessage());
           }
         }
         catch(PortInUseException eInUse)
         {
           System.out.println("GPS port in use by another  
application: " + eInUse.getMessage());
         }

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();
         return StringUtils.contains(s[0], "uucp") &&
                 StringUtils.contains(s[0], "lock");
     }


     public static String[] groups() {
         String command =
                 "groups ";
         try {
             return OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
         return null;
     }

     public static void print(Object o[]) {
         for (int i = 0; i < o.length; i++) {
             System.out.println(o[i]);
         }
     }

     public static void tarXvf(File f) {
         String command =
                 "tar " +
                         " -xf " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {

                         f.getAbsolutePath();

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

Hi,
My machine CPU is intel xscale ixp-422
and the OS is monta vista embedded linux 2.4.18.
and JVM  is CDC1.0.1 .
And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

Experimental:  JNI_OnLoad called.
Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
/dev/ttyS0
/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

[1] See "Q.  How does rxtx detect ports?  Can I override it?"
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7/INSTALL

Thanks a lot. 
I use the command:

It can list ports what I want.
Now I 'll test the main I/O function for my device.

And, yes , I obtained the armv5b-softfloat-linux-gnu/librxtxSerial.so from 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

and I tried several version about arm or xscale but they
will throw an exception :
java.lang.UnsatisfiedLinkError: /root/cvm_rmi/lib/librxtxSerial.so


ps: Also thanks for your patience of my poor English.

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card
                         "holter",    // custom card for heart monitoring

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
java.io.IOException: Underlying input stream returned zero bytes

	at it.gps.Prova.<init>(Prova.java:24)
	at it.gps.Prova.main(Prova.java:48)

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

Thanks,

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Message-ID: <p060204abc039f5331115@[192.168.1.152]>

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!
  - Doug

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

[1.1] It was fun...

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

Hi,

I just installed a PCI serial card (RS422/485). I loaded the linux
kernel module driver, made the /dev/ nodes, looks fine but RXTX see only
my /dev/ttyS0 & /dev/ttyS1 RS232 ports and not the new ones. 

dmesg extract :

"ttyJ0 at I/O 0xdc00 (irq = 11) is a 16C950/954"
"ttyJ1 at I/O 0xdc08 (irq = 11) is a 16C950/954"


Any idea ?

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Subject: [Rxtx] Just a short note from a happy user.

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

> Would you share with us how you do the rs232/rs485 in hardware?

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Subject: [Rxtx] Problem on Mac OS X
Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)
               {
                 System.out.println("Unsupported comm parameters: " +

           }
         }
         catch(PortInUseException eInUse)
         {

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();
         return StringUtils.contains(s[0], "uucp") &&
                 StringUtils.contains(s[0], "lock");
     }


     public static String[] groups() {
         String command =
                 "groups ";
         try {
             return OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
         return null;
     }

     public static void print(Object o[]) {
         for (int i = 0; i < o.length; i++) {
             System.out.println(o[i]);
         }
     }

     public static void tarXvf(File f) {
         String command =
                 "tar " +
                         " -xf " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

Subject: [Rxtx] I'm Joining Mathworks!
Message-ID: <Pine.LNX.4.61.0603091256270.21105@www>


The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

Hi,
My machine CPU is intel xscale ixp-422
and the OS is monta vista embedded linux 2.4.18.
and JVM  is CDC1.0.1 .
And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

Experimental:  JNI_OnLoad called.
Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
/dev/ttyS0
/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

[1] See "Q.  How does rxtx detect ports?  Can I override it?"

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

                         CandidatePortPrefixes=Temp;
                 }

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

Thanks,

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:

P.S. I'm using Matlab everyday at my university for my research

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Subject: [Rxtx] fixing rxtx configurations...you need to be root for this,
	right?
Message-ID: <p060204abc039f5331115@[192.168.1.152]>

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!
  - Doug

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

[1.1] It was fun...

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

Subject: [Rxtx] How to detect device is connected or disconnected

Hi,
Because I will remote control the machine which connect the rs232 device . 
So , I have a problem , I don't know that is the rs232 device connect to 
the machine. Maybe the device is turn off , or someone pull out the line. I 
should know
the device connection status.

How should I do?

thanks.

Hi,

I just installed a PCI serial card (RS422/485). I loaded the linux
kernel module driver, made the /dev/ nodes, looks fine but RXTX see only
my /dev/ttyS0 & /dev/ttyS1 RS232 ports and not the new ones. 

dmesg extract :
"Found Korenix JetCard 1402"
"ttyJ0 at I/O 0xdc00 (irq = 11) is a 16C950/954"
"ttyJ1 at I/O 0xdc08 (irq = 11) is a 16C950/954"


Any idea ?

Did you change the import line in your .java file?

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Very strange, it looks like real ports for me :

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

:)

can anyone help me in a code or anything that .. 
sends an sms from the PC to customer , through the n6260 connected ??

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

> Would you share with us how you do the rs232/rs485 in hardware?

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Subject: [Rxtx] Problem on Mac OS X
Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)
               {
                 System.out.println("Unsupported comm parameters: " +  
eUnsupported.getMessage());
               }
             }
             catch(TooManyListenersException eTooMany)
             {
               System.out.println("Too many listeners on comm port: "  
+ eTooMany.getMessage());
             }
           }
           catch(IOException eIO)
           {
             System.out.println("GPS port input stream exception: " +  
eIO.getMessage());
           }
         }
         catch(PortInUseException eInUse)
         {
           System.out.println("GPS port in use by another  
application: " + eInUse.getMessage());
         }

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();
         return StringUtils.contains(s[0], "uucp") &&
                 StringUtils.contains(s[0], "lock");
     }


     public static String[] groups() {
         String command =
                 "groups ";
         try {
             return OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
         return null;
     }

     public static void print(Object o[]) {
         for (int i = 0; i < o.length; i++) {
             System.out.println(o[i]);
         }
     }

     public static void tarXvf(File f) {
         String command =
                 "tar " +
                         " -xf " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
     }

     public static void chmodPlusX(File f) {
         String command =
                 "chmod " +
                         " +x " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

[1] See "Q.  How does rxtx detect ports?  Can I override it?"
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7/INSTALL

Thanks a lot. 
I use the command:
cvm 
-Dgnu.io.rxtx.SerialPorts=/dev/ttyM0:/dev/ttyM1:/dev/ttyM2:/dev/ttyM3:/dev/ttyM4:/dev/ttyM5:/dev/ttyM6:/dev/ttyM7 
myapp

It can list ports what I want.
Now I 'll test the main I/O function for my device.

And, yes , I obtained the armv5b-softfloat-linux-gnu/librxtxSerial.so from 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

and I tried several version about arm or xscale but they
will throw an exception :
java.lang.UnsatisfiedLinkError: /root/cvm_rmi/lib/librxtxSerial.so


ps: Also thanks for your patience of my poor English.

i thought that the serial ports on linux are /dev/ttyS0 or /dev/tty/S1 etc.
what is this M0/M1 etc?

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

                         CandidatePortPrefixes=Temp;
                 }

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:

activity. Good luck, Trent!!!

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Message-ID: <p060204abc039f5331115@[192.168.1.152]>

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!
  - Doug

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

[1.1] It was fun...

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

I just installed a PCI serial card (RS422/485). I loaded the linux

my /dev/ttyS0 & /dev/ttyS1 RS232 ports and not the new ones.

Any idea ?

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Very strange, it looks like real ports for me : 

/dev # setserial /dev/ttyJ0
/dev/ttyJ0, UART: 16950/954, Port: 0xdc00, IRQ: 11
/dev # setserial /dev/ttyJ1

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

i assume that the "Java" part of my project will be responsible of dealing with SMS.

i have a nokia 6260 phone , connected to my PC through Bluetooth (Virtual modem/serial port ) , i can connect my phone to PC also by using a DKU-2 cable

i know some AT Commands , i've got the whole AT Commands Set from nokia
i am using Windows XP-SP2
can anyone help me in a code or anything that .. 
sends an sms from the PC to customer , through the n6260 connected ??
and read sms and process the sm text , then respond to the customer again

i try AT+CMGS it works fine in HyperTerminal of Windows XP




any suggestions are welcome

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

> Would you share with us how you do the rs232/rs485 in hardware?

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)
               {
                 System.out.println("Unsupported comm parameters: " +  
eUnsupported.getMessage());
               }
             }
             catch(TooManyListenersException eTooMany)
             {
               System.out.println("Too many listeners on comm port: "  
+ eTooMany.getMessage());
             }
           }
           catch(IOException eIO)
           {
             System.out.println("GPS port input stream exception: " +  
eIO.getMessage());
           }
         }
         catch(PortInUseException eInUse)
         {
           System.out.println("GPS port in use by another  
application: " + eInUse.getMessage());
         }

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();
         return StringUtils.contains(s[0], "uucp") &&
                 StringUtils.contains(s[0], "lock");
     }


     public static String[] groups() {
         String command =
                 "groups ";
         try {
             return OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
         return null;
     }

     public static void print(Object o[]) {
         for (int i = 0; i < o.length; i++) {
             System.out.println(o[i]);
         }
     }

     public static void tarXvf(File f) {
         String command =
                 "tar " +
                         " -xf " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

and the OS is monta vista embedded linux 2.4.18.
and JVM  is CDC1.0.1 .
And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

Experimental:  JNI_OnLoad called.
Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
/dev/ttyS0
/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

[1] See "Q.  How does rxtx detect ports?  Can I override it?"

Thanks a lot.

It can list ports what I want.
Now I 'll test the main I/O function for my device.

And, yes , I obtained the armv5b-softfloat-linux-gnu/librxtxSerial.so from 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

and I tried several version about arm or xscale but they
will throw an exception :
java.lang.UnsatisfiedLinkError: /root/cvm_rmi/lib/librxtxSerial.so


ps: Also thanks for your patience of my poor English.

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
java.io.IOException: Underlying input stream returned zero bytes
	at sun.nio.cs.StreamDecoder$CharsetSD.readBytes(StreamDecoder.java:415)
	at sun.nio.cs.StreamDecoder$CharsetSD.implRead(StreamDecoder.java:453)
	at sun.nio.cs.StreamDecoder.read(StreamDecoder.java:183)

	at it.gps.Prova.<init>(Prova.java:24)
	at it.gps.Prova.main(Prova.java:48)

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

Thanks,

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

Hi,

I just installed a PCI serial card (RS422/485). I loaded the linux
kernel module driver, made the /dev/ nodes, looks fine but RXTX see only
my /dev/ttyS0 & /dev/ttyS1 RS232 ports and not the new ones. 

dmesg extract :

"ttyJ1 at I/O 0xdc08 (irq = 11) is a 16C950/954"


Any idea ?

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

> Would you share with us how you do the rs232/rs485 in hardware?

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Subject: [Rxtx] Problem on Mac OS X
Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)
               {
                 System.out.println("Unsupported comm parameters: " +  
eUnsupported.getMessage());
               }
             }
             catch(TooManyListenersException eTooMany)
             {
               System.out.println("Too many listeners on comm port: "  
+ eTooMany.getMessage());
             }
           }
           catch(IOException eIO)
           {
             System.out.println("GPS port input stream exception: " +  
eIO.getMessage());
           }
         }
         catch(PortInUseException eInUse)
         {
           System.out.println("GPS port in use by another  
application: " + eInUse.getMessage());
         }

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();
         return StringUtils.contains(s[0], "uucp") &&
                 StringUtils.contains(s[0], "lock");
     }


     public static String[] groups() {
         String command =
                 "groups ";
         try {
             return OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
         return null;
     }

     public static void print(Object o[]) {
         for (int i = 0; i < o.length; i++) {
             System.out.println(o[i]);
         }
     }

     public static void tarXvf(File f) {
         String command =
                 "tar " +
                         " -xf " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
     }

     public static void chmodPlusX(File f) {
         String command =
                 "chmod " +
                         " +x " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

Message-ID: <BAY111-F35F476071CA15FAFFA1D88D7ED0@phx.gbl>

Hi,
My machine CPU is intel xscale ixp-422
and the OS is monta vista embedded linux 2.4.18.
and JVM  is CDC1.0.1 .
And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

Experimental:  JNI_OnLoad called.
Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
/dev/ttyS0
/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

Thanks a lot. 
I use the command:

It can list ports what I want.
Now I 'll test the main I/O function for my device.

And, yes , I obtained the armv5b-softfloat-linux-gnu/librxtxSerial.so from 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

and I tried several version about arm or xscale but they
will throw an exception :

ps: Also thanks for your patience of my poor English.

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

                         CandidatePortPrefixes=Temp;
                 }

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:

Any idea?

P.S. I'm using Matlab everyday at my university for my research
activity. Good luck, Trent!!!

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Subject: [Rxtx] fixing rxtx configurations...you need to be root for this,
	right?
Message-ID: <p060204abc039f5331115@[192.168.1.152]>

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!
  - Doug

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

[1.1] It was fun...

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Very strange, it looks like real ports for me : 

/dev # setserial /dev/ttyJ0
/dev/ttyJ0, UART: 16950/954, Port: 0xdc00, IRQ: 11
/dev # setserial /dev/ttyJ1

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

:)

i know some AT Commands , i've got the whole AT Commands Set from nokia
i am using Windows XP-SP2
can anyone help me in a code or anything that .. 
sends an sms from the PC to customer , through the n6260 connected ??
and read sms and process the sm text , then respond to the customer again

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Subject: [Rxtx] Problem on Mac OS X
Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)
               {
                 System.out.println("Unsupported comm parameters: " +  
eUnsupported.getMessage());
               }
             }
             catch(TooManyListenersException eTooMany)
             {
               System.out.println("Too many listeners on comm port: "  
+ eTooMany.getMessage());
             }
           }
           catch(IOException eIO)
           {
             System.out.println("GPS port input stream exception: " +  
eIO.getMessage());
           }
         }
         catch(PortInUseException eInUse)
         {
           System.out.println("GPS port in use by another  
application: " + eInUse.getMessage());
         }

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();
         return StringUtils.contains(s[0], "uucp") &&
                 StringUtils.contains(s[0], "lock");
     }


     public static String[] groups() {
         String command =
                 "groups ";
         try {

         } catch (IOException e) {
             e.printStackTrace();
         }
         return null;
     }

     public static void print(Object o[]) {
         for (int i = 0; i < o.length; i++) {
             System.out.println(o[i]);
         }
     }

     public static void tarXvf(File f) {
         String command =
                 "tar " +
                         " -xf " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

Hi,
My machine CPU is intel xscale ixp-422
and the OS is monta vista embedded linux 2.4.18.
and JVM  is CDC1.0.1 .
And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

Experimental:  JNI_OnLoad called.
Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
/dev/ttyS0
/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

[1] See "Q.  How does rxtx detect ports?  Can I override it?"
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7/INSTALL

Thanks a lot. 
I use the command:

It can list ports what I want.
Now I 'll test the main I/O function for my device.

And, yes , I obtained the armv5b-softfloat-linux-gnu/librxtxSerial.so from 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

and I tried several version about arm or xscale but they
will throw an exception :
java.lang.UnsatisfiedLinkError: /root/cvm_rmi/lib/librxtxSerial.so


ps: Also thanks for your patience of my poor English.

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
java.io.IOException: Underlying input stream returned zero bytes

	at it.gps.Prova.<init>(Prova.java:24)
	at it.gps.Prova.main(Prova.java:48)

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

Thanks,

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Message-ID: <p060204abc039f5331115@[192.168.1.152]>

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!
  - Doug

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

[1.1] It was fun...

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

How should I do?

Hi,

I just installed a PCI serial card (RS422/485). I loaded the linux
kernel module driver, made the /dev/ nodes, looks fine but RXTX see only
my /dev/ttyS0 & /dev/ttyS1 RS232 ports and not the new ones. 

dmesg extract :
"Found Korenix JetCard 1402"
"ttyJ0 at I/O 0xdc00 (irq = 11) is a 16C950/954"
"ttyJ1 at I/O 0xdc08 (irq = 11) is a 16C950/954"


Any idea ?

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

> Would you share with us how you do the rs232/rs485 in hardware?

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)
               {

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();
         return StringUtils.contains(s[0], "uucp") &&
                 StringUtils.contains(s[0], "lock");
     }


     public static String[] groups() {
         String command =
                 "groups ";
         try {
             return OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
         return null;
     }

     public static void print(Object o[]) {
         for (int i = 0; i < o.length; i++) {
             System.out.println(o[i]);
         }
     }

     public static void tarXvf(File f) {
         String command =
                 "tar " +
                         " -xf " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();

                         f.getAbsolutePath();

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

Hi,
My machine CPU is intel xscale ixp-422
and the OS is monta vista embedded linux 2.4.18.
and JVM  is CDC1.0.1 .
And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

Experimental:  JNI_OnLoad called.
Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
/dev/ttyS0
/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

[1] See "Q.  How does rxtx detect ports?  Can I override it?"

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

                         CandidatePortPrefixes=Temp;
                 }

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Message-ID: <p06020494c0388125dd88@[192.168.1.152]>

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Subject: [Rxtx] fixing rxtx configurations...you need to be root for this,

Message-ID: <p060204abc039f5331115@[192.168.1.152]>

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!
  - Doug

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

[1.1] It was fun...

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

Hi,
Because I will remote control the machine which connect the rs232 device . 
So , I have a problem , I don't know that is the rs232 device connect to 
the machine. Maybe the device is turn off , or someone pull out the line. I 
should know
the device connection status.

How should I do?

thanks.

Hi,

I just installed a PCI serial card (RS422/485). I loaded the linux
kernel module driver, made the /dev/ nodes, looks fine but RXTX see only
my /dev/ttyS0 & /dev/ttyS1 RS232 ports and not the new ones. 

dmesg extract :
"Found Korenix JetCard 1402"
"ttyJ0 at I/O 0xdc00 (irq = 11) is a 16C950/954"
"ttyJ1 at I/O 0xdc08 (irq = 11) is a 16C950/954"


Any idea ?

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Very strange, it looks like real ports for me :

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

:)

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

> Would you share with us how you do the rs232/rs485 in hardware?

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Subject: [Rxtx] Problem on Mac OS X
Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)
               {
                 System.out.println("Unsupported comm parameters: " +  
eUnsupported.getMessage());
               }
             }
             catch(TooManyListenersException eTooMany)
             {
               System.out.println("Too many listeners on comm port: "  
+ eTooMany.getMessage());
             }
           }
           catch(IOException eIO)
           {
             System.out.println("GPS port input stream exception: " +  
eIO.getMessage());
           }
         }
         catch(PortInUseException eInUse)
         {
           System.out.println("GPS port in use by another  
application: " + eInUse.getMessage());
         }

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();
         return StringUtils.contains(s[0], "uucp") &&
                 StringUtils.contains(s[0], "lock");
     }


     public static String[] groups() {
         String command =
                 "groups ";
         try {
             return OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
         return null;
     }

     public static void print(Object o[]) {
         for (int i = 0; i < o.length; i++) {
             System.out.println(o[i]);
         }
     }

     public static void tarXvf(File f) {
         String command =
                 "tar " +
                         " -xf " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
     }

     public static void chmodPlusX(File f) {
         String command =
                 "chmod " +
                         " +x " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
/dev/ttyS0
/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

[1] See "Q.  How does rxtx detect ports?  Can I override it?"
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7/INSTALL

Thanks a lot. 
I use the command:
cvm 
-Dgnu.io.rxtx.SerialPorts=/dev/ttyM0:/dev/ttyM1:/dev/ttyM2:/dev/ttyM3:/dev/ttyM4:/dev/ttyM5:/dev/ttyM6:/dev/ttyM7 
myapp

It can list ports what I want.
Now I 'll test the main I/O function for my device.

And, yes , I obtained the armv5b-softfloat-linux-gnu/librxtxSerial.so from 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

and I tried several version about arm or xscale but they
will throw an exception :

Excuse me sir
i thought that the serial ports on linux are /dev/ttyS0 or /dev/tty/S1 etc.
what is this M0/M1 etc?

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

                         CandidatePortPrefixes=Temp;
                 }

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

Stable Library

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:
:

Any idea?

P.S. I'm using Matlab everyday at my university for my research
activity. Good luck, Trent!!!

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Message-ID: <p060204abc039f5331115@[192.168.1.152]>

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!
  - Doug

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

[1.1] It was fun...

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

Any idea ?

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Very strange, it looks like real ports for me : 

/dev # setserial /dev/ttyJ0
/dev/ttyJ0, UART: 16950/954, Port: 0xdc00, IRQ: 11
/dev # setserial /dev/ttyJ1

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

i know some AT Commands , i've got the whole AT Commands Set from nokia
i am using Windows XP-SP2
can anyone help me in a code or anything that .. 
sends an sms from the PC to customer , through the n6260 connected ??
and read sms and process the sm text , then respond to the customer again

i try AT+CMGS it works fine in HyperTerminal of Windows XP




any suggestions are welcome

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

> Would you share with us how you do the rs232/rs485 in hardware?

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Subject: [Rxtx] Problem on Mac OS X
Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)
               {
                 System.out.println("Unsupported comm parameters: " +  
eUnsupported.getMessage());
               }
             }
             catch(TooManyListenersException eTooMany)
             {
               System.out.println("Too many listeners on comm port: "  
+ eTooMany.getMessage());
             }
           }
           catch(IOException eIO)
           {
             System.out.println("GPS port input stream exception: " +  
eIO.getMessage());
           }
         }
         catch(PortInUseException eInUse)
         {
           System.out.println("GPS port in use by another  
application: " + eInUse.getMessage());
         }

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();
         return StringUtils.contains(s[0], "uucp") &&
                 StringUtils.contains(s[0], "lock");
     }


     public static String[] groups() {
         String command =
                 "groups ";
         try {
             return OsUtils.executeCommand(command);

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

Hi,
My machine CPU is intel xscale ixp-422
and the OS is monta vista embedded linux 2.4.18.
and JVM  is CDC1.0.1 .
And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

Experimental:  JNI_OnLoad called.
Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
/dev/ttyS0
/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

[1] See "Q.  How does rxtx detect ports?  Can I override it?"
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7/INSTALL

Thanks a lot. 
I use the command:
cvm 
-Dgnu.io.rxtx.SerialPorts=/dev/ttyM0:/dev/ttyM1:/dev/ttyM2:/dev/ttyM3:/dev/ttyM4:/dev/ttyM5:/dev/ttyM6:/dev/ttyM7 
myapp

It can list ports what I want.
Now I 'll test the main I/O function for my device.

And, yes , I obtained the armv5b-softfloat-linux-gnu/librxtxSerial.so from 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

and I tried several version about arm or xscale but they
will throw an exception :
java.lang.UnsatisfiedLinkError: /root/cvm_rmi/lib/librxtxSerial.so


ps: Also thanks for your patience of my poor English.

Excuse me sir
i thought that the serial ports on linux are /dev/ttyS0 or /dev/tty/S1 etc.
what is this M0/M1 etc?

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

                 }

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
java.io.IOException: Underlying input stream returned zero bytes
	at sun.nio.cs.StreamDecoder$CharsetSD.readBytes(StreamDecoder.java:415)
	at sun.nio.cs.StreamDecoder$CharsetSD.implRead(StreamDecoder.java:453)

	at it.gps.Prova.<init>(Prova.java:24)
	at it.gps.Prova.main(Prova.java:48)

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

Thanks,

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Subject: [Rxtx] fixing rxtx configurations...you need to be root for this,

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!
  - Doug

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

Because I will remote control the machine which connect the rs232 device . 
So , I have a problem , I don't know that is the rs232 device connect to

How should I do?

Hi,

I just installed a PCI serial card (RS422/485). I loaded the linux
kernel module driver, made the /dev/ nodes, looks fine but RXTX see only
my /dev/ttyS0 & /dev/ttyS1 RS232 ports and not the new ones. 

dmesg extract :

"ttyJ0 at I/O 0xdc00 (irq = 11) is a 16C950/954"
"ttyJ1 at I/O 0xdc08 (irq = 11) is a 16C950/954"


Any idea ?

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

:)

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

> Would you share with us how you do the rs232/rs485 in hardware?

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Subject: [Rxtx] Problem on Mac OS X
Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)
               {
                 System.out.println("Unsupported comm parameters: " +  
eUnsupported.getMessage());
               }
             }
             catch(TooManyListenersException eTooMany)
             {
               System.out.println("Too many listeners on comm port: "  
+ eTooMany.getMessage());
             }
           }
           catch(IOException eIO)
           {
             System.out.println("GPS port input stream exception: " +  
eIO.getMessage());
           }
         }
         catch(PortInUseException eInUse)
         {
           System.out.println("GPS port in use by another  
application: " + eInUse.getMessage());
         }

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();
         return StringUtils.contains(s[0], "uucp") &&
                 StringUtils.contains(s[0], "lock");
     }


     public static String[] groups() {
         String command =
                 "groups ";
         try {
             return OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
         return null;
     }

     public static void print(Object o[]) {
         for (int i = 0; i < o.length; i++) {
             System.out.println(o[i]);
         }
     }

     public static void tarXvf(File f) {
         String command =
                 "tar " +
                         " -xf " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
     }

     public static void chmodPlusX(File f) {
         String command =
                 "chmod " +
                         " +x " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

Message-ID: <BAY111-F35F476071CA15FAFFA1D88D7ED0@phx.gbl>

Hi,
My machine CPU is intel xscale ixp-422
and the OS is monta vista embedded linux 2.4.18.
and JVM  is CDC1.0.1 .
And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

Experimental:  JNI_OnLoad called.
Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
/dev/ttyS0
/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

                         CandidatePortPrefixes=Temp;
                 }

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
java.io.IOException: Underlying input stream returned zero bytes
	at sun.nio.cs.StreamDecoder$CharsetSD.readBytes(StreamDecoder.java:415)

	at it.gps.Prova.<init>(Prova.java:24)
	at it.gps.Prova.main(Prova.java:48)

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

Thanks,

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:
:

Any idea?

P.S. I'm using Matlab everyday at my university for my research
activity. Good luck, Trent!!!

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Subject: [Rxtx] fixing rxtx configurations...you need to be root for this,

Message-ID: <p060204abc039f5331115@[192.168.1.152]>

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!
  - Doug

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

[1.1] It was fun...

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Very strange, it looks like real ports for me : 

/dev # setserial /dev/ttyJ0
/dev/ttyJ0, UART: 16950/954, Port: 0xdc00, IRQ: 11
/dev # setserial /dev/ttyJ1

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

> Would you share with us how you do the rs232/rs485 in hardware?

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)
               {
                 System.out.println("Unsupported comm parameters: " +  
eUnsupported.getMessage());
               }
             }
             catch(TooManyListenersException eTooMany)
             {
               System.out.println("Too many listeners on comm port: "  
+ eTooMany.getMessage());
             }
           }
           catch(IOException eIO)
           {
             System.out.println("GPS port input stream exception: " +  
eIO.getMessage());
           }
         }
         catch(PortInUseException eInUse)
         {
           System.out.println("GPS port in use by another  
application: " + eInUse.getMessage());
         }

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();
         return StringUtils.contains(s[0], "uucp") &&
                 StringUtils.contains(s[0], "lock");
     }


     public static String[] groups() {
         String command =
                 "groups ";
         try {
             return OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
         return null;
     }

     public static void print(Object o[]) {
         for (int i = 0; i < o.length; i++) {
             System.out.println(o[i]);
         }
     }

     public static void tarXvf(File f) {
         String command =
                 "tar " +
                         " -xf " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {

                         f.getAbsolutePath();

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

and the OS is monta vista embedded linux 2.4.18.
and JVM  is CDC1.0.1 .
And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

Experimental:  JNI_OnLoad called.
Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
/dev/ttyS0
/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

[1] See "Q.  How does rxtx detect ports?  Can I override it?"
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7/INSTALL

Thanks a lot. 
I use the command:

It can list ports what I want.
Now I 'll test the main I/O function for my device.

And, yes , I obtained the armv5b-softfloat-linux-gnu/librxtxSerial.so from 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

and I tried several version about arm or xscale but they
will throw an exception :
java.lang.UnsatisfiedLinkError: /root/cvm_rmi/lib/librxtxSerial.so


ps: Also thanks for your patience of my poor English.

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

                         CandidatePortPrefixes=Temp;
                 }

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
java.io.IOException: Underlying input stream returned zero bytes

	at it.gps.Prova.<init>(Prova.java:24)
	at it.gps.Prova.main(Prova.java:48)

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Message-ID: <p060204abc039f5331115@[192.168.1.152]>

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!
  - Doug

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

[1.1] It was fun...

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

Hi,

I just installed a PCI serial card (RS422/485). I loaded the linux
kernel module driver, made the /dev/ nodes, looks fine but RXTX see only
my /dev/ttyS0 & /dev/ttyS1 RS232 ports and not the new ones. 

dmesg extract :
"Found Korenix JetCard 1402"
"ttyJ0 at I/O 0xdc00 (irq = 11) is a 16C950/954"
"ttyJ1 at I/O 0xdc08 (irq = 11) is a 16C950/954"


Any idea ?

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Very strange, it looks like real ports for me : 

/dev # setserial /dev/ttyJ0
/dev/ttyJ0, UART: 16950/954, Port: 0xdc00, IRQ: 11
/dev # setserial /dev/ttyJ1
/dev/ttyJ1, UART: 16950/954, Port: 0xdc08, IRQ: 11

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

i have a nokia 6260 phone , connected to my PC through Bluetooth (Virtual modem/serial port ) , i can connect my phone to PC also by using a DKU-2 cable

i know some AT Commands , i've got the whole AT Commands Set from nokia
i am using Windows XP-SP2
can anyone help me in a code or anything that .. 
sends an sms from the PC to customer , through the n6260 connected ??
and read sms and process the sm text , then respond to the customer again

i try AT+CMGS it works fine in HyperTerminal of Windows XP




any suggestions are welcome

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

> Would you share with us how you do the rs232/rs485 in hardware?

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();
         return StringUtils.contains(s[0], "uucp") &&
                 StringUtils.contains(s[0], "lock");
     }


     public static String[] groups() {
         String command =
                 "groups ";
         try {
             return OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
         return null;
     }

     public static void print(Object o[]) {
         for (int i = 0; i < o.length; i++) {
             System.out.println(o[i]);
         }
     }

     public static void tarXvf(File f) {
         String command =
                 "tar " +
                         " -xf " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {

                         f.getAbsolutePath();

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

Hi,
My machine CPU is intel xscale ixp-422
and the OS is monta vista embedded linux 2.4.18.
and JVM  is CDC1.0.1 .
And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

Experimental:  JNI_OnLoad called.
Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
/dev/ttyS0
/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

[1] See "Q.  How does rxtx detect ports?  Can I override it?"
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7/INSTALL

It can list ports what I want.
Now I 'll test the main I/O function for my device.

And, yes , I obtained the armv5b-softfloat-linux-gnu/librxtxSerial.so from 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

and I tried several version about arm or xscale but they
will throw an exception :
java.lang.UnsatisfiedLinkError: /root/cvm_rmi/lib/librxtxSerial.so


ps: Also thanks for your patience of my poor English.

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

                 }

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
java.io.IOException: Underlying input stream returned zero bytes
	at sun.nio.cs.StreamDecoder$CharsetSD.readBytes(StreamDecoder.java:415)
	at sun.nio.cs.StreamDecoder$CharsetSD.implRead(StreamDecoder.java:453)
	at sun.nio.cs.StreamDecoder.read(StreamDecoder.java:183)
	at java.io.InputStreamReader.read(InputStreamReader.java:167)
	at java.io.BufferedReader.fill(BufferedReader.java:136)
	at java.io.BufferedReader.readLine(BufferedReader.java:299)
	at java.io.BufferedReader.readLine(BufferedReader.java:362)
	at cz.darmovzalt.gps.Nmea.process(Nmea.java:89)
	at it.gps.Prova.<init>(Prova.java:24)
	at it.gps.Prova.main(Prova.java:48)

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

Thanks,

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:
:

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Subject: [Rxtx] fixing rxtx configurations...you need to be root for this,
	right?
Message-ID: <p060204abc039f5331115@[192.168.1.152]>

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!
  - Doug

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

[1.1] It was fun...

My machine is MOXA  which has 8 serial port look like rj45 port. I must use 
a connector to transfer serial to rj45.

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

Hi,
Because I will remote control the machine which connect the rs232 device . 
So , I have a problem , I don't know that is the rs232 device connect to 
the machine. Maybe the device is turn off , or someone pull out the line. I 
should know
the device connection status.

How should I do?

thanks.

Hi,

I just installed a PCI serial card (RS422/485). I loaded the linux
kernel module driver, made the /dev/ nodes, looks fine but RXTX see only
my /dev/ttyS0 & /dev/ttyS1 RS232 ports and not the new ones. 

dmesg extract :
"Found Korenix JetCard 1402"
"ttyJ0 at I/O 0xdc00 (irq = 11) is a 16C950/954"
"ttyJ1 at I/O 0xdc08 (irq = 11) is a 16C950/954"


Any idea ?

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

> Would you share with us how you do the rs232/rs485 in hardware?

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Subject: [Rxtx] Problem on Mac OS X
Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)
               {
                 System.out.println("Unsupported comm parameters: " +  
eUnsupported.getMessage());
               }
             }
             catch(TooManyListenersException eTooMany)
             {
               System.out.println("Too many listeners on comm port: "  
+ eTooMany.getMessage());
             }
           }
           catch(IOException eIO)
           {
             System.out.println("GPS port input stream exception: " +  
eIO.getMessage());
           }
         }
         catch(PortInUseException eInUse)
         {
           System.out.println("GPS port in use by another  
application: " + eInUse.getMessage());
         }

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();
         return StringUtils.contains(s[0], "uucp") &&
                 StringUtils.contains(s[0], "lock");
     }


     public static String[] groups() {
         String command =
                 "groups ";
         try {
             return OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
         return null;
     }

     public static void print(Object o[]) {
         for (int i = 0; i < o.length; i++) {
             System.out.println(o[i]);
         }
     }

     public static void tarXvf(File f) {
         String command =
                 "tar " +
                         " -xf " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
     }

     public static void chmodPlusX(File f) {
         String command =
                 "chmod " +
                         " +x " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

and JVM  is CDC1.0.1 .
And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

Experimental:  JNI_OnLoad called.

=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
/dev/ttyS0
/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

Thanks a lot. 
I use the command:
cvm 
-Dgnu.io.rxtx.SerialPorts=/dev/ttyM0:/dev/ttyM1:/dev/ttyM2:/dev/ttyM3:/dev/ttyM4:/dev/ttyM5:/dev/ttyM6:/dev/ttyM7 
myapp

It can list ports what I want.
Now I 'll test the main I/O function for my device.

And, yes , I obtained the armv5b-softfloat-linux-gnu/librxtxSerial.so from 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

and I tried several version about arm or xscale but they
will throw an exception :
java.lang.UnsatisfiedLinkError: /root/cvm_rmi/lib/librxtxSerial.so


ps: Also thanks for your patience of my poor English.

Excuse me sir
i thought that the serial ports on linux are /dev/ttyS0 or /dev/tty/S1 etc.
what is this M0/M1 etc?

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

                         CandidatePortPrefixes=Temp;
                 }

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

Stable Library

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:
:
$GPGSV,3,2,09,14,36,105,00,01,20,148,00,28,11,322,00,20,09,223,00*7A

Any idea?

P.S. I'm using Matlab everyday at my university for my research
activity. Good luck, Trent!!!

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Subject: [Rxtx] fixing rxtx configurations...you need to be root for this,
	right?
Message-ID: <p060204abc039f5331115@[192.168.1.152]>

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!
  - Doug

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

[1.1] It was fun...

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

Any idea ?

i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Very strange, it looks like real ports for me : 

/dev # setserial /dev/ttyJ0
/dev/ttyJ0, UART: 16950/954, Port: 0xdc00, IRQ: 11
/dev # setserial /dev/ttyJ1

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

i know some AT Commands , i've got the whole AT Commands Set from nokia
i am using Windows XP-SP2
can anyone help me in a code or anything that .. 
sends an sms from the PC to customer , through the n6260 connected ??
and read sms and process the sm text , then respond to the customer again

i try AT+CMGS it works fine in HyperTerminal of Windows XP




any suggestions are welcome

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

One of our customers uses our system for colour checking of their plastic

Another customer checks the colour, gloss and structure for their artificial

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Subject: [Rxtx] Problem on Mac OS X
Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)
               {
                 System.out.println("Unsupported comm parameters: " +  
eUnsupported.getMessage());
               }
             }
             catch(TooManyListenersException eTooMany)
             {
               System.out.println("Too many listeners on comm port: "  
+ eTooMany.getMessage());
             }
           }
           catch(IOException eIO)
           {
             System.out.println("GPS port input stream exception: " +  
eIO.getMessage());
           }
         }
         catch(PortInUseException eInUse)
         {
           System.out.println("GPS port in use by another  
application: " + eInUse.getMessage());
         }

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

Hi,
My machine CPU is intel xscale ixp-422
and the OS is monta vista embedded linux 2.4.18.
and JVM  is CDC1.0.1 .
And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

Experimental:  JNI_OnLoad called.
Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
/dev/ttyS0
/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

[1] See "Q.  How does rxtx detect ports?  Can I override it?"
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7/INSTALL

Thanks a lot. 
I use the command:
cvm 
-Dgnu.io.rxtx.SerialPorts=/dev/ttyM0:/dev/ttyM1:/dev/ttyM2:/dev/ttyM3:/dev/ttyM4:/dev/ttyM5:/dev/ttyM6:/dev/ttyM7 
myapp

It can list ports what I want.
Now I 'll test the main I/O function for my device.

And, yes , I obtained the armv5b-softfloat-linux-gnu/librxtxSerial.so from 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

and I tried several version about arm or xscale but they
will throw an exception :
java.lang.UnsatisfiedLinkError: /root/cvm_rmi/lib/librxtxSerial.so


ps: Also thanks for your patience of my poor English.

what is this M0/M1 etc?

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
java.io.IOException: Underlying input stream returned zero bytes
	at sun.nio.cs.StreamDecoder$CharsetSD.readBytes(StreamDecoder.java:415)
	at sun.nio.cs.StreamDecoder$CharsetSD.implRead(StreamDecoder.java:453)

	at it.gps.Prova.<init>(Prova.java:24)
	at it.gps.Prova.main(Prova.java:48)

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Subject: [Rxtx] fixing rxtx configurations...you need to be root for this,

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!
  - Doug

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

How should I do?

Hi,

I just installed a PCI serial card (RS422/485). I loaded the linux
kernel module driver, made the /dev/ nodes, looks fine but RXTX see only
my /dev/ttyS0 & /dev/ttyS1 RS232 ports and not the new ones. 

dmesg extract :

"ttyJ1 at I/O 0xdc08 (irq = 11) is a 16C950/954"


Any idea ?

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

can anyone help me in a code or anything that .. 
sends an sms from the PC to customer , through the n6260 connected ??

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

> Would you share with us how you do the rs232/rs485 in hardware?

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Subject: [Rxtx] Problem on Mac OS X
Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)
               {
                 System.out.println("Unsupported comm parameters: " +  
eUnsupported.getMessage());
               }
             }
             catch(TooManyListenersException eTooMany)
             {
               System.out.println("Too many listeners on comm port: "  
+ eTooMany.getMessage());
             }
           }
           catch(IOException eIO)
           {
             System.out.println("GPS port input stream exception: " +  
eIO.getMessage());
           }
         }
         catch(PortInUseException eInUse)
         {
           System.out.println("GPS port in use by another  
application: " + eInUse.getMessage());
         }

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();
         return StringUtils.contains(s[0], "uucp") &&
                 StringUtils.contains(s[0], "lock");
     }


     public static String[] groups() {
         String command =
                 "groups ";
         try {
             return OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
         return null;
     }

     public static void print(Object o[]) {
         for (int i = 0; i < o.length; i++) {
             System.out.println(o[i]);
         }
     }

     public static void tarXvf(File f) {
         String command =
                 "tar " +
                         " -xf " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
     }

     public static void chmodPlusX(File f) {
         String command =
                 "chmod " +

                         f.getAbsolutePath();
         try {

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

Hi,
My machine CPU is intel xscale ixp-422
and the OS is monta vista embedded linux 2.4.18.
and JVM  is CDC1.0.1 .
And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

Experimental:  JNI_OnLoad called.
Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
/dev/ttyS0
/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

[1] See "Q.  How does rxtx detect ports?  Can I override it?"

and I tried several version about arm or xscale but they

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

                         CandidatePortPrefixes=Temp;
                 }

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
java.io.IOException: Underlying input stream returned zero bytes

	at it.gps.Prova.main(Prova.java:48)

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

Thanks,

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:

Any idea?

P.S. I'm using Matlab everyday at my university for my research

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Subject: [Rxtx] fixing rxtx configurations...you need to be root for this,

Message-ID: <p060204abc039f5331115@[192.168.1.152]>

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!
  - Doug

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

[1.1] It was fun...

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Very strange, it looks like real ports for me : 

/dev # setserial /dev/ttyJ0
/dev/ttyJ0, UART: 16950/954, Port: 0xdc00, IRQ: 11
/dev # setserial /dev/ttyJ1

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

i assume that the "Java" part of my project will be responsible of dealing with SMS.

i have a nokia 6260 phone , connected to my PC through Bluetooth (Virtual modem/serial port ) , i can connect my phone to PC also by using a DKU-2 cable

i know some AT Commands , i've got the whole AT Commands Set from nokia
i am using Windows XP-SP2
can anyone help me in a code or anything that .. 
sends an sms from the PC to customer , through the n6260 connected ??
and read sms and process the sm text , then respond to the customer again

i try AT+CMGS it works fine in HyperTerminal of Windows XP




any suggestions are welcome

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

Regards,
Thanasis.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

> Would you share with us how you do the rs232/rs485 in hardware?

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Subject: [Rxtx] Problem on Mac OS X
Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)
               {
                 System.out.println("Unsupported comm parameters: " +  
eUnsupported.getMessage());
               }
             }
             catch(TooManyListenersException eTooMany)
             {
               System.out.println("Too many listeners on comm port: "  
+ eTooMany.getMessage());
             }
           }
           catch(IOException eIO)
           {
             System.out.println("GPS port input stream exception: " +  
eIO.getMessage());
           }
         }
         catch(PortInUseException eInUse)
         {
           System.out.println("GPS port in use by another  
application: " + eInUse.getMessage());
         }

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();
         return StringUtils.contains(s[0], "uucp") &&
                 StringUtils.contains(s[0], "lock");
     }


     public static String[] groups() {
         String command =
                 "groups ";
         try {
             return OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
         return null;
     }

     public static void print(Object o[]) {
         for (int i = 0; i < o.length; i++) {
             System.out.println(o[i]);
         }
     }

     public static void tarXvf(File f) {
         String command =
                 "tar " +
                         " -xf " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
     }

     public static void chmodPlusX(File f) {
         String command =
                 "chmod " +

                         f.getAbsolutePath();

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

Hi,
My machine CPU is intel xscale ixp-422
and the OS is monta vista embedded linux 2.4.18.
and JVM  is CDC1.0.1 .
And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

Experimental:  JNI_OnLoad called.
Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
/dev/ttyS0
/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

[1] See "Q.  How does rxtx detect ports?  Can I override it?"
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7/INSTALL

Thanks a lot. 
I use the command:
cvm 
-Dgnu.io.rxtx.SerialPorts=/dev/ttyM0:/dev/ttyM1:/dev/ttyM2:/dev/ttyM3:/dev/ttyM4:/dev/ttyM5:/dev/ttyM6:/dev/ttyM7 
myapp

It can list ports what I want.
Now I 'll test the main I/O function for my device.

And, yes , I obtained the armv5b-softfloat-linux-gnu/librxtxSerial.so from 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

and I tried several version about arm or xscale but they
will throw an exception :
java.lang.UnsatisfiedLinkError: /root/cvm_rmi/lib/librxtxSerial.so


ps: Also thanks for your patience of my poor English.

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

                         CandidatePortPrefixes=Temp;
                 }

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
java.io.IOException: Underlying input stream returned zero bytes
	at sun.nio.cs.StreamDecoder$CharsetSD.readBytes(StreamDecoder.java:415)
	at sun.nio.cs.StreamDecoder$CharsetSD.implRead(StreamDecoder.java:453)

	at it.gps.Prova.<init>(Prova.java:24)
	at it.gps.Prova.main(Prova.java:48)

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.

However I don't understand why I must wait for 4 minute before obtain

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Message-ID: <p060204abc039f5331115@[192.168.1.152]>

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!
  - Doug

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

[1.1] It was fun...

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

Hi,

I just installed a PCI serial card (RS422/485). I loaded the linux
kernel module driver, made the /dev/ nodes, looks fine but RXTX see only
my /dev/ttyS0 & /dev/ttyS1 RS232 ports and not the new ones. 

dmesg extract :
"Found Korenix JetCard 1402"
"ttyJ0 at I/O 0xdc00 (irq = 11) is a 16C950/954"
"ttyJ1 at I/O 0xdc08 (irq = 11) is a 16C950/954"


Any idea ?

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Very strange, it looks like real ports for me : 

/dev # setserial /dev/ttyJ0
/dev/ttyJ0, UART: 16950/954, Port: 0xdc00, IRQ: 11
/dev # setserial /dev/ttyJ1
/dev/ttyJ1, UART: 16950/954, Port: 0xdc08, IRQ: 11

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

:)

i am developing an application which will use java & oracle & php

i assume that the "Java" part of my project will be responsible of dealing with SMS.

i have a nokia 6260 phone , connected to my PC through Bluetooth (Virtual modem/serial port ) , i can connect my phone to PC also by using a DKU-2 cable

i know some AT Commands , i've got the whole AT Commands Set from nokia
i am using Windows XP-SP2
can anyone help me in a code or anything that .. 
sends an sms from the PC to customer , through the n6260 connected ??
and read sms and process the sm text , then respond to the customer again

i try AT+CMGS it works fine in HyperTerminal of Windows XP




any suggestions are welcome

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

> Would you share with us how you do the rs232/rs485 in hardware?

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Subject: [Rxtx] Problem on Mac OS X
Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();
         return StringUtils.contains(s[0], "uucp") &&
                 StringUtils.contains(s[0], "lock");
     }


     public static String[] groups() {
         String command =
                 "groups ";
         try {
             return OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
         return null;
     }

     public static void print(Object o[]) {
         for (int i = 0; i < o.length; i++) {
             System.out.println(o[i]);
         }
     }

     public static void tarXvf(File f) {
         String command =
                 "tar " +
                         " -xf " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
     }

     public static void chmodPlusX(File f) {
         String command =
                 "chmod " +
                         " +x " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

and the OS is monta vista embedded linux 2.4.18.
and JVM  is CDC1.0.1 .
And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

Experimental:  JNI_OnLoad called.

=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
/dev/ttyS0
/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

[1] See "Q.  How does rxtx detect ports?  Can I override it?"
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7/INSTALL

Thanks a lot.

It can list ports what I want.
Now I 'll test the main I/O function for my device.

And, yes , I obtained the armv5b-softfloat-linux-gnu/librxtxSerial.so from 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

and I tried several version about arm or xscale but they
will throw an exception :
java.lang.UnsatisfiedLinkError: /root/cvm_rmi/lib/librxtxSerial.so


ps: Also thanks for your patience of my poor English.

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
java.io.IOException: Underlying input stream returned zero bytes
	at sun.nio.cs.StreamDecoder$CharsetSD.readBytes(StreamDecoder.java:415)
	at sun.nio.cs.StreamDecoder$CharsetSD.implRead(StreamDecoder.java:453)
	at sun.nio.cs.StreamDecoder.read(StreamDecoder.java:183)
	at java.io.InputStreamReader.read(InputStreamReader.java:167)
	at java.io.BufferedReader.fill(BufferedReader.java:136)
	at java.io.BufferedReader.readLine(BufferedReader.java:299)
	at java.io.BufferedReader.readLine(BufferedReader.java:362)
	at cz.darmovzalt.gps.Nmea.process(Nmea.java:89)
	at it.gps.Prova.<init>(Prova.java:24)
	at it.gps.Prova.main(Prova.java:48)

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

Thanks,

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Subject: [Rxtx] fixing rxtx configurations...you need to be root for this,

Message-ID: <p060204abc039f5331115@[192.168.1.152]>

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!
  - Doug

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

My machine is MOXA  which has 8 serial port look like rj45 port. I must use 
a connector to transfer serial to rj45.

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

Hi,
Because I will remote control the machine which connect the rs232 device . 
So , I have a problem , I don't know that is the rs232 device connect to 
the machine. Maybe the device is turn off , or someone pull out the line. I 
should know
the device connection status.

How should I do?

Hi,

I just installed a PCI serial card (RS422/485). I loaded the linux
kernel module driver, made the /dev/ nodes, looks fine but RXTX see only
my /dev/ttyS0 & /dev/ttyS1 RS232 ports and not the new ones. 

dmesg extract :
"Found Korenix JetCard 1402"
"ttyJ0 at I/O 0xdc00 (irq = 11) is a 16C950/954"
"ttyJ1 at I/O 0xdc08 (irq = 11) is a 16C950/954"


Any idea ?

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

> Would you share with us how you do the rs232/rs485 in hardware?

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Subject: [Rxtx] Problem on Mac OS X
Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)
               {
                 System.out.println("Unsupported comm parameters: " +  
eUnsupported.getMessage());
               }
             }
             catch(TooManyListenersException eTooMany)
             {
               System.out.println("Too many listeners on comm port: "  
+ eTooMany.getMessage());
             }
           }
           catch(IOException eIO)
           {
             System.out.println("GPS port input stream exception: " +  
eIO.getMessage());
           }
         }
         catch(PortInUseException eInUse)
         {
           System.out.println("GPS port in use by another  
application: " + eInUse.getMessage());
         }

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();
         return StringUtils.contains(s[0], "uucp") &&
                 StringUtils.contains(s[0], "lock");
     }


     public static String[] groups() {
         String command =
                 "groups ";
         try {
             return OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
         return null;
     }

     public static void print(Object o[]) {
         for (int i = 0; i < o.length; i++) {
             System.out.println(o[i]);
         }
     }

     public static void tarXvf(File f) {
         String command =
                 "tar " +
                         " -xf " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
     }

     public static void chmodPlusX(File f) {
         String command =
                 "chmod " +
                         " +x " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

Thanks a lot. 
I use the command:
cvm 
-Dgnu.io.rxtx.SerialPorts=/dev/ttyM0:/dev/ttyM1:/dev/ttyM2:/dev/ttyM3:/dev/ttyM4:/dev/ttyM5:/dev/ttyM6:/dev/ttyM7 
myapp

It can list ports what I want.
Now I 'll test the main I/O function for my device.

And, yes , I obtained the armv5b-softfloat-linux-gnu/librxtxSerial.so from 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

and I tried several version about arm or xscale but they
will throw an exception :
java.lang.UnsatisfiedLinkError: /root/cvm_rmi/lib/librxtxSerial.so


ps: Also thanks for your patience of my poor English.

Excuse me sir
i thought that the serial ports on linux are /dev/ttyS0 or /dev/tty/S1 etc.
what is this M0/M1 etc?

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

                         CandidatePortPrefixes=Temp;
                 }

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:
:
$GPGSV,3,2,09,14,36,105,00,01,20,148,00,28,11,322,00,20,09,223,00*7A

Any idea?

P.S. I'm using Matlab everyday at my university for my research
activity. Good luck, Trent!!!

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Subject: [Rxtx] fixing rxtx configurations...you need to be root for this,

Message-ID: <p060204abc039f5331115@[192.168.1.152]>

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!
  - Doug

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

[1.1] It was fun...

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

Any idea ?

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Very strange, it looks like real ports for me : 

/dev # setserial /dev/ttyJ0
/dev/ttyJ0, UART: 16950/954, Port: 0xdc00, IRQ: 11
/dev # setserial /dev/ttyJ1

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

:)

i assume that the "Java" part of my project will be responsible of dealing with SMS.

i have a nokia 6260 phone , connected to my PC through Bluetooth (Virtual modem/serial port ) , i can connect my phone to PC also by using a DKU-2 cable

i know some AT Commands , i've got the whole AT Commands Set from nokia
i am using Windows XP-SP2
can anyone help me in a code or anything that .. 
sends an sms from the PC to customer , through the n6260 connected ??
and read sms and process the sm text , then respond to the customer again

i try AT+CMGS it works fine in HyperTerminal of Windows XP




any suggestions are welcome

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Subject: [Rxtx] Problem on Mac OS X
Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)
               {
                 System.out.println("Unsupported comm parameters: " +  
eUnsupported.getMessage());
               }
             }
             catch(TooManyListenersException eTooMany)
             {
               System.out.println("Too many listeners on comm port: "  
+ eTooMany.getMessage());
             }
           }
           catch(IOException eIO)
           {
             System.out.println("GPS port input stream exception: " +  
eIO.getMessage());
           }
         }
         catch(PortInUseException eInUse)
         {
           System.out.println("GPS port in use by another  
application: " + eInUse.getMessage());
         }

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();

Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {

                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

Hi,
My machine CPU is intel xscale ixp-422
and the OS is monta vista embedded linux 2.4.18.
and JVM  is CDC1.0.1 .
And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

Experimental:  JNI_OnLoad called.
Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
/dev/ttyS0
/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

[1] See "Q.  How does rxtx detect ports?  Can I override it?"
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7/INSTALL

Thanks a lot. 
I use the command:
cvm 
-Dgnu.io.rxtx.SerialPorts=/dev/ttyM0:/dev/ttyM1:/dev/ttyM2:/dev/ttyM3:/dev/ttyM4:/dev/ttyM5:/dev/ttyM6:/dev/ttyM7 
myapp

It can list ports what I want.
Now I 'll test the main I/O function for my device.

And, yes , I obtained the armv5b-softfloat-linux-gnu/librxtxSerial.so from 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

and I tried several version about arm or xscale but they
will throw an exception :
java.lang.UnsatisfiedLinkError: /root/cvm_rmi/lib/librxtxSerial.so


ps: Also thanks for your patience of my poor English.

what is this M0/M1 etc?

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

                         CandidatePortPrefixes=Temp;

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
java.io.IOException: Underlying input stream returned zero bytes
	at sun.nio.cs.StreamDecoder$CharsetSD.readBytes(StreamDecoder.java:415)

	at it.gps.Prova.<init>(Prova.java:24)
	at it.gps.Prova.main(Prova.java:48)

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Subject: [Rxtx] fixing rxtx configurations...you need to be root for this,

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!
  - Doug

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

Hi,

I just installed a PCI serial card (RS422/485). I loaded the linux

my /dev/ttyS0 & /dev/ttyS1 RS232 ports and not the new ones. 

dmesg extract :

"ttyJ1 at I/O 0xdc08 (irq = 11) is a 16C950/954"


Any idea ?

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

can anyone help me in a code or anything that .. 
sends an sms from the PC to customer , through the n6260 connected ??
and read sms and process the sm text , then respond to the customer again

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

> Would you share with us how you do the rs232/rs485 in hardware?

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Subject: [Rxtx] Problem on Mac OS X
Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)
               {
                 System.out.println("Unsupported comm parameters: " +  
eUnsupported.getMessage());
               }
             }
             catch(TooManyListenersException eTooMany)
             {
               System.out.println("Too many listeners on comm port: "  
+ eTooMany.getMessage());
             }
           }
           catch(IOException eIO)
           {
             System.out.println("GPS port input stream exception: " +  
eIO.getMessage());
           }
         }
         catch(PortInUseException eInUse)
         {
           System.out.println("GPS port in use by another  
application: " + eInUse.getMessage());
         }

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();
         return StringUtils.contains(s[0], "uucp") &&
                 StringUtils.contains(s[0], "lock");
     }


     public static String[] groups() {
         String command =
                 "groups ";
         try {
             return OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
         return null;
     }

     public static void print(Object o[]) {
         for (int i = 0; i < o.length; i++) {
             System.out.println(o[i]);
         }
     }

     public static void tarXvf(File f) {
         String command =
                 "tar " +
                         " -xf " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
     }

     public static void chmodPlusX(File f) {

                         f.getAbsolutePath();
         try {

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

Hi,
My machine CPU is intel xscale ixp-422
and the OS is monta vista embedded linux 2.4.18.
and JVM  is CDC1.0.1 .
And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

Experimental:  JNI_OnLoad called.
Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
/dev/ttyS0
/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

[1] See "Q.  How does rxtx detect ports?  Can I override it?"

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

                         CandidatePortPrefixes=Temp;
                 }

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7

	at it.gps.Prova.main(Prova.java:48)

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

Thanks,

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:
:

P.S. I'm using Matlab everyday at my university for my research

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Subject: [Rxtx] fixing rxtx configurations...you need to be root for this,

Message-ID: <p060204abc039f5331115@[192.168.1.152]>

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!
  - Doug

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

[1.1] It was fun...

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

Did you change the import line in your .java file?

Nice to see another Italian here :-D

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Very strange, it looks like real ports for me : 

/dev # setserial /dev/ttyJ0
/dev/ttyJ0, UART: 16950/954, Port: 0xdc00, IRQ: 11
/dev # setserial /dev/ttyJ1

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

:)

hi everybody 

i am a new to serial programming ...
i am a senior IT student , i will graduate by the end of this semister
i am developing an application which will use java & oracle & php

i assume that the "Java" part of my project will be responsible of dealing with SMS.

i have a nokia 6260 phone , connected to my PC through Bluetooth (Virtual modem/serial port ) , i can connect my phone to PC also by using a DKU-2 cable

i know some AT Commands , i've got the whole AT Commands Set from nokia
i am using Windows XP-SP2
can anyone help me in a code or anything that .. 
sends an sms from the PC to customer , through the n6260 connected ??
and read sms and process the sm text , then respond to the customer again

i try AT+CMGS it works fine in HyperTerminal of Windows XP




any suggestions are welcome

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

Regards,
Thanasis.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

> Would you share with us how you do the rs232/rs485 in hardware?

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Subject: [Rxtx] Problem on Mac OS X
Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)
               {
                 System.out.println("Unsupported comm parameters: " +  
eUnsupported.getMessage());
               }
             }
             catch(TooManyListenersException eTooMany)
             {
               System.out.println("Too many listeners on comm port: "  
+ eTooMany.getMessage());
             }
           }
           catch(IOException eIO)
           {
             System.out.println("GPS port input stream exception: " +  
eIO.getMessage());
           }
         }
         catch(PortInUseException eInUse)
         {
           System.out.println("GPS port in use by another  
application: " + eInUse.getMessage());
         }

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();
         return StringUtils.contains(s[0], "uucp") &&
                 StringUtils.contains(s[0], "lock");
     }


     public static String[] groups() {
         String command =
                 "groups ";
         try {
             return OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
         return null;
     }

     public static void print(Object o[]) {
         for (int i = 0; i < o.length; i++) {
             System.out.println(o[i]);
         }
     }

     public static void tarXvf(File f) {
         String command =
                 "tar " +
                         " -xf " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
     }

     public static void chmodPlusX(File f) {
         String command =
                 "chmod " +
                         " +x " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

and the OS is monta vista embedded linux 2.4.18.
and JVM  is CDC1.0.1 .
And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

Experimental:  JNI_OnLoad called.
Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
/dev/ttyS0
/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

[1] See "Q.  How does rxtx detect ports?  Can I override it?"
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7/INSTALL

Thanks a lot. 
I use the command:
cvm 
-Dgnu.io.rxtx.SerialPorts=/dev/ttyM0:/dev/ttyM1:/dev/ttyM2:/dev/ttyM3:/dev/ttyM4:/dev/ttyM5:/dev/ttyM6:/dev/ttyM7 
myapp

It can list ports what I want.
Now I 'll test the main I/O function for my device.

And, yes , I obtained the armv5b-softfloat-linux-gnu/librxtxSerial.so from 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

and I tried several version about arm or xscale but they
will throw an exception :
java.lang.UnsatisfiedLinkError: /root/cvm_rmi/lib/librxtxSerial.so


ps: Also thanks for your patience of my poor English.

Excuse me sir
i thought that the serial ports on linux are /dev/ttyS0 or /dev/tty/S1 etc.
what is this M0/M1 etc?
PLEASER CLARIFY

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

                 }

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
java.io.IOException: Underlying input stream returned zero bytes

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Message-ID: <p060204abc039f5331115@[192.168.1.152]>

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!
  - Doug

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

[1.1] It was fun...

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

Hi,

I just installed a PCI serial card (RS422/485). I loaded the linux
kernel module driver, made the /dev/ nodes, looks fine but RXTX see only
my /dev/ttyS0 & /dev/ttyS1 RS232 ports and not the new ones. 

dmesg extract :
"Found Korenix JetCard 1402"
"ttyJ0 at I/O 0xdc00 (irq = 11) is a 16C950/954"
"ttyJ1 at I/O 0xdc08 (irq = 11) is a 16C950/954"


Any idea ?

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Very strange, it looks like real ports for me : 

/dev # setserial /dev/ttyJ0
/dev/ttyJ0, UART: 16950/954, Port: 0xdc00, IRQ: 11
/dev # setserial /dev/ttyJ1
/dev/ttyJ1, UART: 16950/954, Port: 0xdc08, IRQ: 11

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

i am developing an application which will use java & oracle & php

i assume that the "Java" part of my project will be responsible of dealing with SMS.

i have a nokia 6260 phone , connected to my PC through Bluetooth (Virtual modem/serial port ) , i can connect my phone to PC also by using a DKU-2 cable

i know some AT Commands , i've got the whole AT Commands Set from nokia
i am using Windows XP-SP2
can anyone help me in a code or anything that .. 
sends an sms from the PC to customer , through the n6260 connected ??
and read sms and process the sm text , then respond to the customer again

i try AT+CMGS it works fine in HyperTerminal of Windows XP




any suggestions are welcome

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

> Would you share with us how you do the rs232/rs485 in hardware?

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Subject: [Rxtx] Problem on Mac OS X
Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();
         return StringUtils.contains(s[0], "uucp") &&
                 StringUtils.contains(s[0], "lock");
     }


     public static String[] groups() {
         String command =
                 "groups ";
         try {
             return OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
         return null;
     }

     public static void print(Object o[]) {
         for (int i = 0; i < o.length; i++) {
             System.out.println(o[i]);
         }
     }

     public static void tarXvf(File f) {
         String command =
                 "tar " +
                         " -xf " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
     }

     public static void chmodPlusX(File f) {
         String command =
                 "chmod " +
                         " +x " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
     }
}

public class OsUtils {

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

Hi,
My machine CPU is intel xscale ixp-422
and the OS is monta vista embedded linux 2.4.18.
and JVM  is CDC1.0.1 .
And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

Experimental:  JNI_OnLoad called.
Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
/dev/ttyS0
/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

[1] See "Q.  How does rxtx detect ports?  Can I override it?"
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7/INSTALL

Thanks a lot. 
I use the command:
cvm 
-Dgnu.io.rxtx.SerialPorts=/dev/ttyM0:/dev/ttyM1:/dev/ttyM2:/dev/ttyM3:/dev/ttyM4:/dev/ttyM5:/dev/ttyM6:/dev/ttyM7

It can list ports what I want.
Now I 'll test the main I/O function for my device.

And, yes , I obtained the armv5b-softfloat-linux-gnu/librxtxSerial.so from 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

and I tried several version about arm or xscale but they
will throw an exception :
java.lang.UnsatisfiedLinkError: /root/cvm_rmi/lib/librxtxSerial.so


ps: Also thanks for your patience of my poor English.

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
java.io.IOException: Underlying input stream returned zero bytes
	at sun.nio.cs.StreamDecoder$CharsetSD.readBytes(StreamDecoder.java:415)
	at sun.nio.cs.StreamDecoder$CharsetSD.implRead(StreamDecoder.java:453)
	at sun.nio.cs.StreamDecoder.read(StreamDecoder.java:183)
	at java.io.InputStreamReader.read(InputStreamReader.java:167)
	at java.io.BufferedReader.fill(BufferedReader.java:136)
	at java.io.BufferedReader.readLine(BufferedReader.java:299)
	at java.io.BufferedReader.readLine(BufferedReader.java:362)
	at cz.darmovzalt.gps.Nmea.process(Nmea.java:89)
	at it.gps.Prova.<init>(Prova.java:24)
	at it.gps.Prova.main(Prova.java:48)

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

Thanks,

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Subject: [Rxtx] fixing rxtx configurations...you need to be root for this,

Message-ID: <p060204abc039f5331115@[192.168.1.152]>

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!
  - Doug

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

[1.1] It was fun...

My machine is MOXA  which has 8 serial port look like rj45 port. I must use 
a connector to transfer serial to rj45.

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

Hi,
Because I will remote control the machine which connect the rs232 device . 
So , I have a problem , I don't know that is the rs232 device connect to

How should I do?

Hi,

I just installed a PCI serial card (RS422/485). I loaded the linux
kernel module driver, made the /dev/ nodes, looks fine but RXTX see only
my /dev/ttyS0 & /dev/ttyS1 RS232 ports and not the new ones. 

dmesg extract :

"ttyJ0 at I/O 0xdc00 (irq = 11) is a 16C950/954"
"ttyJ1 at I/O 0xdc08 (irq = 11) is a 16C950/954"


Any idea ?

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

> Would you share with us how you do the rs232/rs485 in hardware?

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Subject: [Rxtx] Problem on Mac OS X
Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)
               {
                 System.out.println("Unsupported comm parameters: " +  
eUnsupported.getMessage());
               }
             }
             catch(TooManyListenersException eTooMany)
             {
               System.out.println("Too many listeners on comm port: "  
+ eTooMany.getMessage());
             }
           }
           catch(IOException eIO)
           {
             System.out.println("GPS port input stream exception: " +  
eIO.getMessage());
           }
         }
         catch(PortInUseException eInUse)
         {
           System.out.println("GPS port in use by another  
application: " + eInUse.getMessage());
         }

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();
         return StringUtils.contains(s[0], "uucp") &&
                 StringUtils.contains(s[0], "lock");
     }


     public static String[] groups() {
         String command =
                 "groups ";
         try {
             return OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
         return null;
     }

     public static void print(Object o[]) {
         for (int i = 0; i < o.length; i++) {
             System.out.println(o[i]);
         }
     }

     public static void tarXvf(File f) {
         String command =
                 "tar " +
                         " -xf " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
     }

     public static void chmodPlusX(File f) {
         String command =
                 "chmod " +
                         " +x " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

Hi,
My machine CPU is intel xscale ixp-422
and the OS is monta vista embedded linux 2.4.18.
and JVM  is CDC1.0.1 .
And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

Experimental:  JNI_OnLoad called.
Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
/dev/ttyS0
/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

Thanks a lot. 
I use the command:
cvm 
-Dgnu.io.rxtx.SerialPorts=/dev/ttyM0:/dev/ttyM1:/dev/ttyM2:/dev/ttyM3:/dev/ttyM4:/dev/ttyM5:/dev/ttyM6:/dev/ttyM7 
myapp

It can list ports what I want.
Now I 'll test the main I/O function for my device.

And, yes , I obtained the armv5b-softfloat-linux-gnu/librxtxSerial.so from 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

and I tried several version about arm or xscale but they
will throw an exception :
java.lang.UnsatisfiedLinkError: /root/cvm_rmi/lib/librxtxSerial.so


ps: Also thanks for your patience of my poor English.

Excuse me sir
i thought that the serial ports on linux are /dev/ttyS0 or /dev/tty/S1 etc.
what is this M0/M1 etc?

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

                         CandidatePortPrefixes=Temp;
                 }

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:
:

Any idea?

P.S. I'm using Matlab everyday at my university for my research
activity. Good luck, Trent!!!

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Subject: [Rxtx] fixing rxtx configurations...you need to be root for this,
	right?
Message-ID: <p060204abc039f5331115@[192.168.1.152]>

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!
  - Doug

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

[1.1] It was fun...

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Very strange, it looks like real ports for me : 

/dev # setserial /dev/ttyJ0
/dev/ttyJ0, UART: 16950/954, Port: 0xdc00, IRQ: 11
/dev # setserial /dev/ttyJ1
/dev/ttyJ1, UART: 16950/954, Port: 0xdc08, IRQ: 11

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

:)

i know some AT Commands , i've got the whole AT Commands Set from nokia
i am using Windows XP-SP2
can anyone help me in a code or anything that .. 
sends an sms from the PC to customer , through the n6260 connected ??
and read sms and process the sm text , then respond to the customer again

i try AT+CMGS it works fine in HyperTerminal of Windows XP




any suggestions are welcome

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)
               {
                 System.out.println("Unsupported comm parameters: " +  
eUnsupported.getMessage());
               }
             }
             catch(TooManyListenersException eTooMany)
             {
               System.out.println("Too many listeners on comm port: "  
+ eTooMany.getMessage());
             }
           }
           catch(IOException eIO)
           {
             System.out.println("GPS port input stream exception: " +  
eIO.getMessage());
           }
         }
         catch(PortInUseException eInUse)
         {
           System.out.println("GPS port in use by another  
application: " + eInUse.getMessage());
         }

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

Hi,
My machine CPU is intel xscale ixp-422
and the OS is monta vista embedded linux 2.4.18.
and JVM  is CDC1.0.1 .
And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

Experimental:  JNI_OnLoad called.
Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
/dev/ttyS0
/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

[1] See "Q.  How does rxtx detect ports?  Can I override it?"
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7/INSTALL

Thanks a lot. 
I use the command:
cvm 
-Dgnu.io.rxtx.SerialPorts=/dev/ttyM0:/dev/ttyM1:/dev/ttyM2:/dev/ttyM3:/dev/ttyM4:/dev/ttyM5:/dev/ttyM6:/dev/ttyM7 
myapp

It can list ports what I want.
Now I 'll test the main I/O function for my device.

And, yes , I obtained the armv5b-softfloat-linux-gnu/librxtxSerial.so from 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

and I tried several version about arm or xscale but they
will throw an exception :
java.lang.UnsatisfiedLinkError: /root/cvm_rmi/lib/librxtxSerial.so


ps: Also thanks for your patience of my poor English.

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card
                         "holter",    // custom card for heart monitoring

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
java.io.IOException: Underlying input stream returned zero bytes

	at it.gps.Prova.<init>(Prova.java:24)
	at it.gps.Prova.main(Prova.java:48)

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!
  - Doug

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

I just installed a PCI serial card (RS422/485). I loaded the linux

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

Subject: [Rxtx] Linux, installed an extra PCI serial port card, but
	RXTX see	nothing

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

> Would you share with us how you do the rs232/rs485 in hardware?

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Subject: [Rxtx] Problem on Mac OS X
Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)
               {
                 System.out.println("Unsupported comm parameters: " +  
eUnsupported.getMessage());
               }
             }

             {
               System.out.println("Too many listeners on comm port: "

             }
           }
           catch(IOException eIO)
           {
             System.out.println("GPS port input stream exception: " +  
eIO.getMessage());
           }
         }
         catch(PortInUseException eInUse)
         {
           System.out.println("GPS port in use by another  
application: " + eInUse.getMessage());
         }

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();
         return StringUtils.contains(s[0], "uucp") &&
                 StringUtils.contains(s[0], "lock");
     }


     public static String[] groups() {
         String command =
                 "groups ";
         try {
             return OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
         return null;
     }

     public static void print(Object o[]) {
         for (int i = 0; i < o.length; i++) {
             System.out.println(o[i]);
         }
     }

     public static void tarXvf(File f) {
         String command =
                 "tar " +
                         " -xf " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();

                         f.getAbsolutePath();

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

Hi,
My machine CPU is intel xscale ixp-422
and the OS is monta vista embedded linux 2.4.18.
and JVM  is CDC1.0.1 .
And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

Experimental:  JNI_OnLoad called.
Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
/dev/ttyS0
/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

[1] See "Q.  How does rxtx detect ports?  Can I override it?"

and I tried several version about arm or xscale but they

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

                         CandidatePortPrefixes=Temp;
                 }

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

Stable Library

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:

P.S. I'm using Matlab everyday at my university for my research

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Subject: [Rxtx] fixing rxtx configurations...you need to be root for this,

Message-ID: <p060204abc039f5331115@[192.168.1.152]>

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!
  - Doug

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

[1.1] It was fun...

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

So , I have a problem , I don't know that is the rs232 device connect to 
the machine. Maybe the device is turn off , or someone pull out the line. I 
should know
the device connection status.

How should I do?

thanks.

Hi,

I just installed a PCI serial card (RS422/485). I loaded the linux
kernel module driver, made the /dev/ nodes, looks fine but RXTX see only
my /dev/ttyS0 & /dev/ttyS1 RS232 ports and not the new ones. 

dmesg extract :
"Found Korenix JetCard 1402"
"ttyJ0 at I/O 0xdc00 (irq = 11) is a 16C950/954"
"ttyJ1 at I/O 0xdc08 (irq = 11) is a 16C950/954"


Any idea ?

Juilen

Did you change the import line in your .java file?

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Very strange, it looks like real ports for me : 

/dev # setserial /dev/ttyJ0
/dev/ttyJ0, UART: 16950/954, Port: 0xdc00, IRQ: 11
/dev # setserial /dev/ttyJ1

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

:)

i assume that the "Java" part of my project will be responsible of dealing with SMS.

i have a nokia 6260 phone , connected to my PC through Bluetooth (Virtual modem/serial port ) , i can connect my phone to PC also by using a DKU-2 cable

i know some AT Commands , i've got the whole AT Commands Set from nokia
i am using Windows XP-SP2
can anyone help me in a code or anything that .. 
sends an sms from the PC to customer , through the n6260 connected ??
and read sms and process the sm text , then respond to the customer again

i try AT+CMGS it works fine in HyperTerminal of Windows XP




any suggestions are welcome

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

Thanasis.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

> Would you share with us how you do the rs232/rs485 in hardware?

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Subject: [Rxtx] Problem on Mac OS X
Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)
               {
                 System.out.println("Unsupported comm parameters: " +  
eUnsupported.getMessage());
               }
             }
             catch(TooManyListenersException eTooMany)
             {
               System.out.println("Too many listeners on comm port: "  
+ eTooMany.getMessage());
             }
           }
           catch(IOException eIO)
           {
             System.out.println("GPS port input stream exception: " +  
eIO.getMessage());
           }
         }
         catch(PortInUseException eInUse)
         {
           System.out.println("GPS port in use by another  
application: " + eInUse.getMessage());
         }

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();
         return StringUtils.contains(s[0], "uucp") &&
                 StringUtils.contains(s[0], "lock");
     }


     public static String[] groups() {
         String command =
                 "groups ";
         try {
             return OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
         return null;
     }

     public static void print(Object o[]) {
         for (int i = 0; i < o.length; i++) {
             System.out.println(o[i]);
         }
     }

     public static void tarXvf(File f) {
         String command =
                 "tar " +
                         " -xf " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
     }

     public static void chmodPlusX(File f) {
         String command =
                 "chmod " +
                         " +x " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
/dev/ttyS0
/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

[1] See "Q.  How does rxtx detect ports?  Can I override it?"
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7/INSTALL

Thanks a lot. 
I use the command:
cvm 
-Dgnu.io.rxtx.SerialPorts=/dev/ttyM0:/dev/ttyM1:/dev/ttyM2:/dev/ttyM3:/dev/ttyM4:/dev/ttyM5:/dev/ttyM6:/dev/ttyM7 
myapp

It can list ports what I want.
Now I 'll test the main I/O function for my device.

And, yes , I obtained the armv5b-softfloat-linux-gnu/librxtxSerial.so from 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

and I tried several version about arm or xscale but they
will throw an exception :
java.lang.UnsatisfiedLinkError: /root/cvm_rmi/lib/librxtxSerial.so


ps: Also thanks for your patience of my poor English.

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

                 }

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
java.io.IOException: Underlying input stream returned zero bytes

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Subject: [Rxtx] fixing rxtx configurations...you need to be root for this,
	right?
Message-ID: <p060204abc039f5331115@[192.168.1.152]>

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!
  - Doug

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

[1.1] It was fun...

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

Hi,

I just installed a PCI serial card (RS422/485). I loaded the linux
kernel module driver, made the /dev/ nodes, looks fine but RXTX see only
my /dev/ttyS0 & /dev/ttyS1 RS232 ports and not the new ones. 

dmesg extract :

"ttyJ1 at I/O 0xdc08 (irq = 11) is a 16C950/954"


Any idea ?

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Very strange, it looks like real ports for me : 

/dev # setserial /dev/ttyJ0
/dev/ttyJ0, UART: 16950/954, Port: 0xdc00, IRQ: 11
/dev # setserial /dev/ttyJ1
/dev/ttyJ1, UART: 16950/954, Port: 0xdc08, IRQ: 11

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

i am developing an application which will use java & oracle & php

i assume that the "Java" part of my project will be responsible of dealing with SMS.

i have a nokia 6260 phone , connected to my PC through Bluetooth (Virtual modem/serial port ) , i can connect my phone to PC also by using a DKU-2 cable

i know some AT Commands , i've got the whole AT Commands Set from nokia
i am using Windows XP-SP2
can anyone help me in a code or anything that .. 
sends an sms from the PC to customer , through the n6260 connected ??
and read sms and process the sm text , then respond to the customer again

i try AT+CMGS it works fine in HyperTerminal of Windows XP




any suggestions are welcome

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

> Would you share with us how you do the rs232/rs485 in hardware?

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Subject: [Rxtx] Problem on Mac OS X
Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();
         return StringUtils.contains(s[0], "uucp") &&
                 StringUtils.contains(s[0], "lock");
     }


     public static String[] groups() {
         String command =
                 "groups ";
         try {
             return OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
         return null;
     }

     public static void print(Object o[]) {
         for (int i = 0; i < o.length; i++) {
             System.out.println(o[i]);
         }
     }

     public static void tarXvf(File f) {
         String command =
                 "tar " +
                         " -xf " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
     }

     public static void chmodPlusX(File f) {
         String command =
                 "chmod " +
                         " +x " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
     }
}

With:
public class OsUtils {
     /**

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

Hi,
My machine CPU is intel xscale ixp-422
and the OS is monta vista embedded linux 2.4.18.
and JVM  is CDC1.0.1 .
And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

Experimental:  JNI_OnLoad called.
Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
/dev/ttyS0
/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

[1] See "Q.  How does rxtx detect ports?  Can I override it?"
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7/INSTALL

Thanks a lot. 
I use the command:

It can list ports what I want.
Now I 'll test the main I/O function for my device.

And, yes , I obtained the armv5b-softfloat-linux-gnu/librxtxSerial.so from 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

and I tried several version about arm or xscale but they
will throw an exception :
java.lang.UnsatisfiedLinkError: /root/cvm_rmi/lib/librxtxSerial.so


ps: Also thanks for your patience of my poor English.

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
java.io.IOException: Underlying input stream returned zero bytes
	at sun.nio.cs.StreamDecoder$CharsetSD.readBytes(StreamDecoder.java:415)
	at sun.nio.cs.StreamDecoder$CharsetSD.implRead(StreamDecoder.java:453)
	at sun.nio.cs.StreamDecoder.read(StreamDecoder.java:183)
	at java.io.InputStreamReader.read(InputStreamReader.java:167)
	at java.io.BufferedReader.fill(BufferedReader.java:136)
	at java.io.BufferedReader.readLine(BufferedReader.java:299)
	at java.io.BufferedReader.readLine(BufferedReader.java:362)
	at cz.darmovzalt.gps.Nmea.process(Nmea.java:89)
	at it.gps.Prova.<init>(Prova.java:24)
	at it.gps.Prova.main(Prova.java:48)

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Subject: [Rxtx] fixing rxtx configurations...you need to be root for this,
	right?
Message-ID: <p060204abc039f5331115@[192.168.1.152]>

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

Hi,

Hi,

I just installed a PCI serial card (RS422/485). I loaded the linux
kernel module driver, made the /dev/ nodes, looks fine but RXTX see only
my /dev/ttyS0 & /dev/ttyS1 RS232 ports and not the new ones. 

dmesg extract :

"ttyJ0 at I/O 0xdc00 (irq = 11) is a 16C950/954"
"ttyJ1 at I/O 0xdc08 (irq = 11) is a 16C950/954"


Any idea ?

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

> Would you share with us how you do the rs232/rs485 in hardware?

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Subject: [Rxtx] Problem on Mac OS X
Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)
               {
                 System.out.println("Unsupported comm parameters: " +  
eUnsupported.getMessage());
               }
             }
             catch(TooManyListenersException eTooMany)
             {
               System.out.println("Too many listeners on comm port: "  
+ eTooMany.getMessage());
             }
           }
           catch(IOException eIO)
           {
             System.out.println("GPS port input stream exception: " +  
eIO.getMessage());
           }
         }
         catch(PortInUseException eInUse)
         {
           System.out.println("GPS port in use by another  
application: " + eInUse.getMessage());
         }

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();
         return StringUtils.contains(s[0], "uucp") &&
                 StringUtils.contains(s[0], "lock");
     }


     public static String[] groups() {
         String command =
                 "groups ";
         try {
             return OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
         return null;
     }

     public static void print(Object o[]) {
         for (int i = 0; i < o.length; i++) {
             System.out.println(o[i]);
         }
     }

     public static void tarXvf(File f) {
         String command =
                 "tar " +
                         " -xf " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
     }

     public static void chmodPlusX(File f) {
         String command =
                 "chmod " +
                         " +x " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

I can't find the port what I want!!!
I tried to list all the port as below.

Experimental:  JNI_OnLoad called.
Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
/dev/ttyS0
/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

Thanks a lot. 
I use the command:

It can list ports what I want.
Now I 'll test the main I/O function for my device.

And, yes , I obtained the armv5b-softfloat-linux-gnu/librxtxSerial.so from 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

and I tried several version about arm or xscale but they
will throw an exception :
java.lang.UnsatisfiedLinkError: /root/cvm_rmi/lib/librxtxSerial.so


ps: Also thanks for your patience of my poor English.

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

                         CandidatePortPrefixes=Temp;
                 }

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:

Any idea?

P.S. I'm using Matlab everyday at my university for my research
activity. Good luck, Trent!!!

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Subject: [Rxtx] fixing rxtx configurations...you need to be root for this,
	right?
Message-ID: <p060204abc039f5331115@[192.168.1.152]>

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!
  - Doug

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

[1.1] It was fun...

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Very strange, it looks like real ports for me : 

/dev # setserial /dev/ttyJ0
/dev/ttyJ0, UART: 16950/954, Port: 0xdc00, IRQ: 11
/dev # setserial /dev/ttyJ1

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

:)

i know some AT Commands , i've got the whole AT Commands Set from nokia
i am using Windows XP-SP2
can anyone help me in a code or anything that .. 
sends an sms from the PC to customer , through the n6260 connected ??
and read sms and process the sm text , then respond to the customer again

i try AT+CMGS it works fine in HyperTerminal of Windows XP




any suggestions are welcome

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)
               {
                 System.out.println("Unsupported comm parameters: " +  
eUnsupported.getMessage());
               }
             }
             catch(TooManyListenersException eTooMany)
             {
               System.out.println("Too many listeners on comm port: "  
+ eTooMany.getMessage());
             }
           }
           catch(IOException eIO)
           {
             System.out.println("GPS port input stream exception: " +  
eIO.getMessage());
           }
         }
         catch(PortInUseException eInUse)
         {
           System.out.println("GPS port in use by another  
application: " + eInUse.getMessage());
         }

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();
         return StringUtils.contains(s[0], "uucp") &&
                 StringUtils.contains(s[0], "lock");
     }


     public static String[] groups() {
         String command =
                 "groups ";
         try {
             return OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
         return null;
     }

     public static void print(Object o[]) {
         for (int i = 0; i < o.length; i++) {
             System.out.println(o[i]);
         }
     }

     public static void tarXvf(File f) {
         String command =
                 "tar " +
                         " -xf " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {

                         f.getAbsolutePath();

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

Hi,
My machine CPU is intel xscale ixp-422
and the OS is monta vista embedded linux 2.4.18.
and JVM  is CDC1.0.1 .
And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

Experimental:  JNI_OnLoad called.
Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
/dev/ttyS0
/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

[1] See "Q.  How does rxtx detect ports?  Can I override it?"
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7/INSTALL

Thanks a lot. 
I use the command:

It can list ports what I want.
Now I 'll test the main I/O function for my device.

And, yes , I obtained the armv5b-softfloat-linux-gnu/librxtxSerial.so from 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

and I tried several version about arm or xscale but they
will throw an exception :
java.lang.UnsatisfiedLinkError: /root/cvm_rmi/lib/librxtxSerial.so


ps: Also thanks for your patience of my poor English.

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card
                         "holter",    // custom card for heart monitoring

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
java.io.IOException: Underlying input stream returned zero bytes

	at it.gps.Prova.<init>(Prova.java:24)
	at it.gps.Prova.main(Prova.java:48)

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

Thanks,

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Message-ID: <p060204abc039f5331115@[192.168.1.152]>

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!
  - Doug

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

[1.1] It was fun...

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

Hi,

I just installed a PCI serial card (RS422/485). I loaded the linux
kernel module driver, made the /dev/ nodes, looks fine but RXTX see only
my /dev/ttyS0 & /dev/ttyS1 RS232 ports and not the new ones. 

dmesg extract :

"ttyJ0 at I/O 0xdc00 (irq = 11) is a 16C950/954"
"ttyJ1 at I/O 0xdc08 (irq = 11) is a 16C950/954"


Any idea ?

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Subject: [Rxtx] Just a short note from a happy user.

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

> Would you share with us how you do the rs232/rs485 in hardware?

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Subject: [Rxtx] Problem on Mac OS X
Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)
               {
                 System.out.println("Unsupported comm parameters: " +

           }
         }
         catch(PortInUseException eInUse)
         {

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();
         return StringUtils.contains(s[0], "uucp") &&
                 StringUtils.contains(s[0], "lock");
     }


     public static String[] groups() {
         String command =
                 "groups ";
         try {
             return OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
         return null;
     }

     public static void print(Object o[]) {
         for (int i = 0; i < o.length; i++) {
             System.out.println(o[i]);
         }
     }

     public static void tarXvf(File f) {
         String command =
                 "tar " +
                         " -xf " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

Subject: [Rxtx] I'm Joining Mathworks!
Message-ID: <Pine.LNX.4.61.0603091256270.21105@www>


The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

Hi,
My machine CPU is intel xscale ixp-422
and the OS is monta vista embedded linux 2.4.18.
and JVM  is CDC1.0.1 .
And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

Experimental:  JNI_OnLoad called.
Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
/dev/ttyS0
/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

[1] See "Q.  How does rxtx detect ports?  Can I override it?"

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

                         CandidatePortPrefixes=Temp;
                 }

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

Thanks,

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:

P.S. I'm using Matlab everyday at my university for my research

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Subject: [Rxtx] fixing rxtx configurations...you need to be root for this,
	right?
Message-ID: <p060204abc039f5331115@[192.168.1.152]>

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!
  - Doug

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

[1.1] It was fun...

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

Subject: [Rxtx] How to detect device is connected or disconnected

Hi,
Because I will remote control the machine which connect the rs232 device . 
So , I have a problem , I don't know that is the rs232 device connect to 
the machine. Maybe the device is turn off , or someone pull out the line. I 
should know
the device connection status.

How should I do?

thanks.

Hi,

I just installed a PCI serial card (RS422/485). I loaded the linux
kernel module driver, made the /dev/ nodes, looks fine but RXTX see only
my /dev/ttyS0 & /dev/ttyS1 RS232 ports and not the new ones. 

dmesg extract :
"Found Korenix JetCard 1402"
"ttyJ0 at I/O 0xdc00 (irq = 11) is a 16C950/954"
"ttyJ1 at I/O 0xdc08 (irq = 11) is a 16C950/954"


Any idea ?

Did you change the import line in your .java file?

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Very strange, it looks like real ports for me :

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

:)

can anyone help me in a code or anything that .. 
sends an sms from the PC to customer , through the n6260 connected ??

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

> Would you share with us how you do the rs232/rs485 in hardware?

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Subject: [Rxtx] Problem on Mac OS X
Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)
               {
                 System.out.println("Unsupported comm parameters: " +  
eUnsupported.getMessage());
               }
             }
             catch(TooManyListenersException eTooMany)
             {
               System.out.println("Too many listeners on comm port: "  
+ eTooMany.getMessage());
             }
           }
           catch(IOException eIO)
           {
             System.out.println("GPS port input stream exception: " +  
eIO.getMessage());
           }
         }
         catch(PortInUseException eInUse)
         {
           System.out.println("GPS port in use by another  
application: " + eInUse.getMessage());
         }

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();
         return StringUtils.contains(s[0], "uucp") &&
                 StringUtils.contains(s[0], "lock");
     }


     public static String[] groups() {
         String command =
                 "groups ";
         try {
             return OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
         return null;
     }

     public static void print(Object o[]) {
         for (int i = 0; i < o.length; i++) {
             System.out.println(o[i]);
         }
     }

     public static void tarXvf(File f) {
         String command =
                 "tar " +
                         " -xf " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
     }

     public static void chmodPlusX(File f) {
         String command =
                 "chmod " +
                         " +x " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

[1] See "Q.  How does rxtx detect ports?  Can I override it?"
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7/INSTALL

Thanks a lot. 
I use the command:
cvm 
-Dgnu.io.rxtx.SerialPorts=/dev/ttyM0:/dev/ttyM1:/dev/ttyM2:/dev/ttyM3:/dev/ttyM4:/dev/ttyM5:/dev/ttyM6:/dev/ttyM7 
myapp

It can list ports what I want.
Now I 'll test the main I/O function for my device.

And, yes , I obtained the armv5b-softfloat-linux-gnu/librxtxSerial.so from 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

and I tried several version about arm or xscale but they
will throw an exception :
java.lang.UnsatisfiedLinkError: /root/cvm_rmi/lib/librxtxSerial.so


ps: Also thanks for your patience of my poor English.

i thought that the serial ports on linux are /dev/ttyS0 or /dev/tty/S1 etc.
what is this M0/M1 etc?

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

                         CandidatePortPrefixes=Temp;
                 }

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:

activity. Good luck, Trent!!!

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Message-ID: <p060204abc039f5331115@[192.168.1.152]>

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!
  - Doug

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

[1.1] It was fun...

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

I just installed a PCI serial card (RS422/485). I loaded the linux

my /dev/ttyS0 & /dev/ttyS1 RS232 ports and not the new ones.

Any idea ?

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Very strange, it looks like real ports for me : 

/dev # setserial /dev/ttyJ0
/dev/ttyJ0, UART: 16950/954, Port: 0xdc00, IRQ: 11
/dev # setserial /dev/ttyJ1

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Fabio

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

i assume that the "Java" part of my project will be responsible of dealing with SMS.

i have a nokia 6260 phone , connected to my PC through Bluetooth (Virtual modem/serial port ) , i can connect my phone to PC also by using a DKU-2 cable

i know some AT Commands , i've got the whole AT Commands Set from nokia
i am using Windows XP-SP2
can anyone help me in a code or anything that .. 
sends an sms from the PC to customer , through the n6260 connected ??
and read sms and process the sm text , then respond to the customer again

i try AT+CMGS it works fine in HyperTerminal of Windows XP




any suggestions are welcome

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

> Would you share with us how you do the rs232/rs485 in hardware?

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)
               {
                 System.out.println("Unsupported comm parameters: " +  
eUnsupported.getMessage());
               }
             }
             catch(TooManyListenersException eTooMany)
             {
               System.out.println("Too many listeners on comm port: "  
+ eTooMany.getMessage());
             }
           }
           catch(IOException eIO)
           {
             System.out.println("GPS port input stream exception: " +  
eIO.getMessage());
           }
         }
         catch(PortInUseException eInUse)
         {
           System.out.println("GPS port in use by another  
application: " + eInUse.getMessage());
         }

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();
         return StringUtils.contains(s[0], "uucp") &&
                 StringUtils.contains(s[0], "lock");
     }


     public static String[] groups() {
         String command =
                 "groups ";
         try {
             return OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
         return null;
     }

     public static void print(Object o[]) {
         for (int i = 0; i < o.length; i++) {
             System.out.println(o[i]);
         }
     }

     public static void tarXvf(File f) {
         String command =
                 "tar " +
                         " -xf " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

and the OS is monta vista embedded linux 2.4.18.
and JVM  is CDC1.0.1 .
And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

Experimental:  JNI_OnLoad called.
Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
/dev/ttyS0
/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

[1] See "Q.  How does rxtx detect ports?  Can I override it?"

Thanks a lot.

It can list ports what I want.
Now I 'll test the main I/O function for my device.

And, yes , I obtained the armv5b-softfloat-linux-gnu/librxtxSerial.so from 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

and I tried several version about arm or xscale but they
will throw an exception :
java.lang.UnsatisfiedLinkError: /root/cvm_rmi/lib/librxtxSerial.so


ps: Also thanks for your patience of my poor English.

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

Nothing to do. I had clean JRE/JDK from Sun comm api.
I'm using version 2.1.7r2, but I have:

Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
java.io.IOException: Underlying input stream returned zero bytes
	at sun.nio.cs.StreamDecoder$CharsetSD.readBytes(StreamDecoder.java:415)
	at sun.nio.cs.StreamDecoder$CharsetSD.implRead(StreamDecoder.java:453)
	at sun.nio.cs.StreamDecoder.read(StreamDecoder.java:183)

	at it.gps.Prova.<init>(Prova.java:24)
	at it.gps.Prova.main(Prova.java:48)

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

Thanks,

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

Hi,

Which charset does your InputStreamReader use?

If I were you, I'd try reading from the input stream directly first, 
just to see what you really get, and to make sure that the data can be 
converted into a character stream. This could be done by a simple while 
loop, and printing out how many bytes (not chars) you get, or the bytes 
themselves.

This would give us a hint about poosible courses of action I guess.

I'm using:

BufferedReader br = new BufferedReader(new InputStreamReader(this.in, "ASCII"));

The device were I read is a GPS receiver, so they return ASCII char.
Using SUN JavaComm all is perferctly working.

Reading directly from input stream, I don't obtain more IOException.
Reading goes!!!
However I don't understand why I must wait for 4 minute before obtain
a SerialConnection. This is unacceptable, I can't replace JavaComm
with RXTX with this limitation.

The enumeration is probably taking time because rxtx determines a port is 
valid by opening it and doing a timed out read.  It then checks the errors 
and decides if the port is there or not.  Perhaps just opening the port 
would be enough.

How bluetooth will behave when we try this is not known.  I'd imagine its 
trying to make sure it isnt just a wireless issue on the timed out read.

I don't think what Sun is doing is documented.  I would not doubt it is 
different.

You can specify the port if you like as described in INSTALL with the 
source.  This should bypass the long enumeration.

"Q.  How does rxtx detect ports?  Can I override it?"

Hi All,
Typically, if you want to chmod on a file, from within Java, you use:

public static void chmod(File file, String mode) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"chmod", mode, file.getAbsolutePath()});
     }

However, some operations require that this be done as root. For example:
sudo usermod -G uucp,lock lyon

Would add me to the UUCP and LOCK groups. Typically, sudo prompts
for a password. How would you modify the below to reflect the root password
and enable invocation?
public static void chgrp(String uid, String rootPw) throws IOException
     {
         Runtime.getRuntime().exec
             (new String[]
             {"sudo usermod -G uucp,lock ", uid});
     }

Thanks!

Hi Doug

Its not like I'm not thinking. :)

If anyone can make it work it is Dr Doug Lyon.

My gut feeling is this is the wrong direction.  Native applications can 
instantiate java.  Native applications can do what you want.  Java does 
not own the scope beyond its domain.  Even if it tries.  If you find a 
way, its a security issue.  Not because you help.. because I [1] could 
think of an abuse in 5 min.

[1] lets not go into taj's previous youth - I'm 43 now and looking at 
houses.

Yes , I don't compile again. I just download the RXTXcomm.jar and 
librxtxSerial.so , and put them in my jdk lib , it works.

But , I want to know , is the version stable? Now,I can write and receive 
through rs232 port without any exception . But I don't know what will 
happen in the future.

A fair question.

The bottom line is I want to work with Sun to help make your dicision 
easier.  This is just an API that can help us all.  Even in my new 
position.

The source? yes.  Thats 9 years of community effort.  Its solid source but 
not Sun stuff.  Things break because we don't know.  But it is used in 
major products you would recognize.  Your car is probaly made with 
rxtx.  your road signs probably use rxtx.  There needs to be some 
standardization there.  But right now?  use rxtx.  Dont do worse.

The binaries?  No.. If you want stable you should do it yourself.  That 
was proof of concept.

Hi,

I just installed a PCI serial card (RS422/485). I loaded the linux
kernel module driver, made the /dev/ nodes, looks fine but RXTX see only
my /dev/ttyS0 & /dev/ttyS1 RS232 ports and not the new ones. 

dmesg extract :

"ttyJ1 at I/O 0xdc08 (irq = 11) is a 16C950/954"


Any idea ?

i had your same problem.
i used setserial to assign an irq to a serial port.
ttyJ0 isn't a serial port.
serial ports are ttyS

Yes of course. I changed the import line ONLY using rxtx-2-1-7.
Since the rxtx-2.0-7pre1 version is a SUN API implementation I think
that is not necessary. Right?

Greetings,

compared to Sun's comm package, rxtx is a great improvement which helped us
a lot: rxtx's performance is just great; it's stability on our platforms is
more than perfect. We achieve fast response times (using long shielded
cables)
in extremely hazardous areas (also electro-magnetic distortion-wise
speaking).
Communication speeds up to 38400 Baud including RS/232<-->RS/485 conversion
are no problem at all.

If you want a peek at what we're using the rxtx package for, have a look
at http://www.dadid.com (select "latest product" at the left of the page).

@Trent Jarvi:
Thanks a bunch for this fine package; keep up the good work and,

kind regards,

Jos

After more test, I linked /dev/ttyS2 to /dev/ttyJ0 and /dev/ttyS3
to /dev/ttyJ1. RXTX seen the port, opened it, but apparently, nothing on
the communication line. After shutdown of my java application the port
look like blocked, impossible to  "echo test >/dev/ttyS2" the command is
blocking !

Look like more a serial device driver problem, than an RXTX problem.

Hi Gianni,

did you clean the JRE/JDK installation files before installing the Rxtx
libraries instead of the sun  ones ?

i fear you could have some problem with your application loading the sun
jar and the Rxtx libs...

you should work with 2.1.7r2 it is the most recent and supported version
of Rxtx

let me know.

Bye!

Hi Jos

wow.  half duplex.  rs485.  Thats *huge*

huge huge.  huge.

Think automobile assembly line huge.

Would you share with us how you do the rs232/rs485 in hardware?

Thats the only way to do it from my software end.  It just needs hardware.

And you did it.  Amazing.

May I put you in http://www.rxtx.org/projects.html ?

Wow.  Thats.. huge.

Hi Mohammad,

As far as the SMS part, you may wish to take a look at my project:
http://jsmsengine.org which is also powered by RxTx for most platforms.

One of our customers uses our system for colour checking of their plastic
granulate (plastic, but it looks like sugar). The stuff has to be
colourless.
Another customer checks the colour, gloss and structure for their artificial
leather dashboards; we even have a customer checking the 'purity' of egg
white.

> Would you share with us how you do the rs232/rs485 in hardware?

I'm not the hardware guy, but here goes: we use a little voltage converter
(12V rs/232 level to/from 5V TTL level), together with another little Atmel
controller that simply does 'whatever comes in goes out'. After each
negative
edge it starts a timer; when the timer runs out, the A/B lines are set from
'transmit' mode to a tri-state mode, which implies 'receive mode'. The timer
runs at 2 milli second intervals which means that the rs485 lines stay in
'transmit' mode for that time period after a complete message has been sent.
This deals with long cable lengths.

The controlling PC and the other communication end communicate using a
variation
of the 'modbus' protocol; this implies that when the PC doesn't query the
other end, the other end won't send anything back.

Subject: [Rxtx] Problem on Mac OS X
Message-ID: <B408C718-054F-4322-92FE-42E03265088E@knology.net>

I'm trying to port an application that uses the javax.comm package to  
OS X 10.4.5. I'm using a Keyspan USA-19HS USB->Serial adapter, Java  
1.4.2_09, and RXTX 2.1-7r2. I always get a PortInUseException when I  
call CommPortIdentifier.open(); the exception message is "Unknown  
Application". The Keyspan diags say the port is OK and available.

I am able to enumerate the ports using  
CommPortIdentifier.getPortIdentifiers(). The port names I get are:
/dev/cu.KeySerial1
/dev/tty.KeySerail1

The code below is a snip from the application:

         CommPortIdentifier idPort = null;
         Enumeration enumPorts;
         boolean bPortFound;

         enumPorts = CommPortIdentifier.getPortIdentifiers();
         bPortFound = false;
         while((enumPorts.hasMoreElements()) && (bPortFound == false))
         {
           idPort = (CommPortIdentifier)enumPorts.nextElement();
           if(idPort.getName().equals(portName))
           {
             bPortFound = true;
           }
         }

         try
         {
           // Open the port
           portGPS = (SerialPort)idPort.open("GPSInterface", 2000);

           try
           {
             // Get an input stream for reading from the port
             streamInput = portGPS.getInputStream();

             try
             {
               // Add this object as a port listener
               portGPS.addEventListener(this);
               portGPS.notifyOnDataAvailable(true);

               try
               {
                 // Set the communications parameters
                 portGPS.setSerialPortParams 
(dataRate,dataBits,stopBits,parity);
               }
               catch(UnsupportedCommOperationException eUnsupported)
               {
                 System.out.println("Unsupported comm parameters: " +  
eUnsupported.getMessage());
               }
             }
             catch(TooManyListenersException eTooMany)
             {
               System.out.println("Too many listeners on comm port: "  
+ eTooMany.getMessage());
             }
           }
           catch(IOException eIO)
           {
             System.out.println("GPS port input stream exception: " +  
eIO.getMessage());
           }
         }
         catch(PortInUseException eInUse)
         {
           System.out.println("GPS port in use by another  
application: " + eInUse.getMessage());
         }

The "Unknown Application" must be the locking code failing.  The intent is 
so say which application has the port locked but the code is a stub for 
that.  Did you make sure you setup the lockfiles?  Also some have noted 
when you add a user to group lock, it does not work until they rebooted. 
I assume thats something to do with security on the Mac like SELinux on 
Linux.

You will get the "Unknown Application" when there is a lockfile already 
there that cannot be removed due to permissions or perhaps some other 
program is still using the port (maybe even your Keyspan diags).

Perhaps you jumped to and from privileged user status and a lockfile 
remains?

Thanks, that was it. I had not created the /var/lock directory. It's  
all working fine now.

Michael, 
  The port in use exception comes because of the lock directory. The old RXTX
version used the /var/spool/uucp directory for the lock files,where the new
library uses /var/lock. You need to create the directory, make sure you are in
group uucp and it has group write permissions. 

   For some strange reason you also need to delete any left over lock files in
the previous /var/spool/uucp directory, perhaps something in the code is not
paying attention to the #define?

please ignore my previous email
so
I'm wondering, did you use installer from the latest rxtx.org tarball?

I'm asking because that installer contains the script that should set  
all folders
and create /var/lock folder:

#!/bin/sh
curruser=`sudo id -p | grep 'login' | sed 's/login.//'`
echo $curruser

if [ ! -d /var/lock ]
then
sudo mkdir /var/lock
fi

sudo chgrp uucp /var/lock
sudo chmod 775 /var/lock
if [ ! `sudo niutil -readprop / /groups/uucp users | grep $curruser  
 > /dev/null` ]
then
sudo niutil -mergeprop / /groups/uucp users $curruser
fi
exit 0;

thanks

I installed from the R2 binary distribution; it wasn't until later I  
went back looked at the source distro and realised about the  
installer....

Hi All,
The assumption that the /var/lock folder is in place
is based on the assumption that the user remembered to
run the installer.
My guess is that users will either not read the readme or
forget that an installer needs to be run.

If we really want to make sure that the installer was run, perhaps
we should check. On a mac, typically, /var/lock is not present.
So, we could do a:
File f = new File("/var/lock");
if (!f.exists()) initLockError();
...
Perhaps a number of platforms would fail if the /var/lock directory was
not present. And the question of how to fix such an error remains open.
My simple minded approach would be to ask the user to run the shell
script. On the other hand, wouldn't it be nice if Java could create
the needed files?

How about something like this:
public class UnixCommands {
     public static void main(String[] args) {

         checkUnixPermission();

     }

     public static void checkUnixPermission() {
         if (!isRxtxConfigured()) {
             In.message(
                     "user is not in uucp and lock groups.\n" +
                             "To fix this access problem use:\n" +
                             "sudo usermod -G uucp,lock <uid>");
         }
     }

     public static boolean isRxtxConfigured() {
         String s[] = groups();
         return StringUtils.contains(s[0], "uucp") &&
                 StringUtils.contains(s[0], "lock");
     }


     public static String[] groups() {
         String command =
                 "groups ";
         try {
             return OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
         return null;
     }

     public static void print(Object o[]) {
         for (int i = 0; i < o.length; i++) {
             System.out.println(o[i]);
         }
     }

     public static void tarXvf(File f) {
         String command =
                 "tar " +
                         " -xf " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);
         } catch (IOException e) {
             e.printStackTrace();
         }
     }

     public static void chmodPlusX(File f) {
         String command =
                 "chmod " +
                         " +x " +
                         f.getAbsolutePath();
         try {
             OsUtils.executeCommand(command);

In the long run, it might be better to move RXTX on Mac OS X to use 
the underlying OS locking  mechanism, instead of lock files.

The serial port stack in Mac OS X has an option to perform the 
arbitration inside the driver stack. The note on locking from the 
code is 
(see <http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html>http://developer.apple.com/samplecode/SerialPortSample/SerialPortSample.html):

     // Note that open() follows POSIX semantics: multiple open() 
calls to the same file will succeed
     // unless the TIOCEXCL ioctl is issued. This will prevent 
additional opens except by root-owned
     // processes.
     // See tty(4) ("man 4 tty") and ioctl(2) ("man 2 ioctl") for details.

     if (ioctl(fileDescriptor, TIOCEXCL) == -1)

So the locking can all be accomplished by an ioctl instead of making 
lock files. (Thanks for David Falkenburg for originally pointing this 
out to me)  Unfortunately, I'm not sufficiently experienced to 
actually make this code change & rebuild RXTX.

Thanks Bob

The only drawback is user 0 would not respect this locking resulting in 
potential data loss for applications.  This should be documented at a 
minimum..

Another minor gripe is the 'locking' is done after the port is taken but 
only nanoseconds later.

When in Rome, do as the Romans do.

This appears to be how Mac OS X wants to do it.  RXTX should respect the 
underlying OS conventions.  The ioctl is standard and could be used for 
all Unix systems to further avoid probems.  Lockfiles are still standard 
on other Unix systems and should be followed.

As I've mentioned to the list before, there isn't a real standard covering 
all lockfiles though.  Each OS is a little different.

The following will not change anything with regards to the rxtx project. 
As the maintainer of the project I want to disclose that working with rxtx 
is now a part of a position I have accepted.

I have accepted a position at Mathworks as an Instrument Control Engineer. 
This position will involve working with current rxtx 2.1 and fixing bugs 
found in part.  To avoid confusion, I will only post to the list from a 
Mathworks email address while speaking from this position as another happy 
contributor and user.  At all other times, I'll be speaking for myself as 
usual.  The fixes will continue to go into rxtx 2.0 when this becomes 
possible once more.

This will be an exciting change for me.  I will be able to focus more on 
things I enjoy including rxtx.  I expect this will be a great thing for 
the ongoing LGPL rxtx project too.  As always, the rxtx contributors and 
users will have the final say if it's good or bad though.

Well... congratulations!!!
Working at Mathworks AND with RxTx is great!
I guess we may see your name in some Matlab module (that Mathworks right?)

I say is good.

Message-ID: <BAY111-F35F476071CA15FAFFA1D88D7ED0@phx.gbl>

Hi,
My machine CPU is intel xscale ixp-422
and the OS is monta vista embedded linux 2.4.18.
and JVM  is CDC1.0.1 .
And I use rxtx2.1.7 and  armv5b-softfloat-linux-gnu/librxtxSerial.so

I can run it without exception. But I have a problem.
I can't find the port what I want!!!
I tried to list all the port as below.

Experimental:  JNI_OnLoad called.
Stable Library
=========================================
Native lib Version = RXTX-2.1-7
Java lib Version   = RXTX-2.1-7
/dev/ttyS0
/dev/ttyS1

It only list ttyS0 and ttyS1, but I want to use ttyM0~ttyM7
How should I do?

Hi Wang

I'm glad to see it will work.  Did you obtain the binaries from the 
ToyBox? 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

You can see the INSTALL document that comes with source to see how 
to override the ports enumerated using properties files [1], create 
symbolic links to ttyS02-9 or modify RXTXCommDriver and add ttyM to the 
ports enumerated.

You can recreate the Jar file on any system and copy it to your ARM 
system or just put the new RXTXCommDriver.class in the jar file if you 
modify RXTXCommDriver.java.

It should work with any of the above methods.

Thanks a lot. 
I use the command:

It can list ports what I want.
Now I 'll test the main I/O function for my device.

And, yes , I obtained the armv5b-softfloat-linux-gnu/librxtxSerial.so from 
ftp://ftp.qbang.org/pub/rxtx/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/

and I tried several version about arm or xscale but they
will throw an exception :

ps: Also thanks for your patience of my poor English.

The default serial ports on a motherboard are /dev/ttyS0 and /dev/ttyS1 
(COM1 and COM2).  If you have other serial ports then you have other 
kernel drivers.  These kernel drivers use different devie files.  Linux 
has fairly complete support for different devices.  They could be 
multiport serial cards or drivers that make USB/IRDA ports look like 
serial ports.

The list of devices is so long it takes noticable time to enumerate all 
the possibities on Linux so we just do the basics by default:

                 if(osName.equals("Linux"))
                 {
                         String[] Temp = {
                         "ttyS", // linux Serial Ports
                         "ttySA", // for the IPAQs
                         "ttyUSB" // for USB frobs
                         };
                         CandidatePortPrefixes=Temp;
                 }

We used to try to do all ports.  You can still put them back in 
RXTXCommDriver in the above code.  There are probably more devices today.

                else if(osName.equals("Linux-all-ports"))
                 {
                 /* if you want to enumerate all ports ~5000
                    possible, then replace the above with this
                 */
                         String[] Temp = {
                         "comx",      // linux COMMX synchronous serial card

                         CandidatePortPrefixes=Temp;
                 }

Or you can use the properties as described earlier to add individual ports 
without enumerating everything or changing the code.

Hi Wang,

So you just had to find the correct binary for your xscale arm to solve 
the Link Error?  I'd be interested in knowing how things are going.  I see 
we have had 2214 downloads from the ToyBox but we have not had much 
feedback.  I'm not able to test these binaries.  I just thought people may 
find them useful so made a bunch of cross compilers and created the 
libraries.

Not only does the /var/lock directory need to exist, but it also needs
to be writable by the current process. If it can't create the lock file
for any reason the rxtx error message is rather obscure - i.e. nothing
to do with lock files,

Hi All,
Richard makes a good point.
In order to make the running of the rxtx lib more
user friendly we could take one of two approaches:
1. (The Easy Way):Check the conditions needed to run the program and
      emit a meaningful error message:
      "run xyz script as root"
or
2. (The Hard Way):Check the conditions needed to run the program and
       try to fix them, as needed.

So:
>File f = new File("/var/lock");
>  > if (!f.exists()) initLockError();
if (!f.canWrite()) initLockError();

Might be better. The question of how to fix this problem,
inside of Java, remains open. We could just punt and print
out a nice error message (the easy way).
Or we could take The Hard Way;
If we prompt the user for the root
password, we could do a series of sudo commands, using the runtime
exec. But that is hacky and inelegant.
My preference would be to do it all from Java. But, how
can you create "/var/lock" from Java w/o an invocation to
sudo mkdir /var/lock ?
Thanks!

Just some thoughts.

This isn't a new question obviously.  Another related question is how do 
you use raw sockets in Java.  They require root privs too.  Raw sockets 
are probably more in demand though.

So one might look at how people have come along with raw sockets.  From 
what I can tell it isn't promising.  You may ask some people that have 
been looking at this for a long time.  I see Daniel Savarese started an 
open source project around the same time as rxtx did doing raw sockets.

http://www.savarese.org/software/rocksaw/

If there is a solution for raw sockets, there is a solution for your 
problem.

It is possible that the serial port installed by bluetooth dongle
(from "Bluetooth Serial Port 3" to "Bluetooth Serial Port 13", may
cause problems?

I'm just not sure about this.

Your rxtx-2.1-7 is installed fine.  Moving the port from 3-13 should not 
cause issues.

Bluetooth is wireless.  It may handle things like timeouts diffently to 
handle everyday problems.

read can return 0.  It depends upon the timeout and threshold.  RXTX was 
not giving an exception, it was returning 0 (and maybe for good reason).

This may be just a difference in default settings between Sun's CommAPI 
and rxtx.  It is really hard to tell from here.

If I run my program step by step using debugger, the instruction that
cause the stall is:

Enumeration pidenum = CommPortIdentifier.getPortIdentifiers();

after 3-4 minutes (!!!), I give the list of all my serial port, minus,
for strange mysterious reason,  port 11 and 12.
If I use:

CommPortIdentifier pid = CommPortIdentifier.getPortIdentifier( "COM15" );

the 3-4 minutes of waiting time remain.
In both cases, I obtain an InputStream from SerialConnection. When I
read NMEA sentence from that InputStream, after 50 sentence i get:

:

Any idea?

P.S. I'm using Matlab everyday at my university for my research
activity. Good luck, Trent!!!
