[Rxtx] CommPortIdentifier open() method and hardware flow control

[Julian Bui]

Hi all,

First time post & newbie.

In some of the examples I see the line:
"portIdentifier.open(this.getClass().getName(),2000);"
What is that 2000?  There is nothing in the documentation about it.  There
isn't anything in the documentation about a lot of things, actually.

What is the difference between the two flow control methods in the
SerialPort class: FLOWCONTROL_RTSCTS_IN and FLOWCONTROL_RTSCTS_OUT.  These
confuse me because I am used to seting "hardware flow control" in
hyperterminal, and not either the in or the out.  Could someone explain what
the difference is and how to use them?  I asked a serial port programmer
what he thought of these and he didn't know.  So I'm in the dark.

Please let me know what you guys know.

Thanks,
Julian
