[Rxtx] Mac commapi

[Dr. Stephen Judd]

This was immensely helpful. Thank you, Tod.
I wish it had been explicit somewhere in the documentation; it would
have saved me 2 days of grief. One hugely valuable thing like this
little set of instructions is that it implicitly lists all the  
hundreds of things
you DON"T have to do.  I know it seems obvious to those in the
know, but every little bit of help on an arcane topic like this opens up
the product to an exponentially wider group of dilettantes.

I managed to get the SerialDemo program (from Sun) to work too. Hurrah!
However, it required changing all the javax.comm references to gnu.io
which I had heard of due to all my rambling readings. Is there not a  
demo
program on rxtx.org already available that would not have needed this?

BTW, the link on the Projects page for
jPIC[Source] sends a *.hex file to a PIC 16F877 or similar chip...
takes me to nowhere useful.

I do not understand what the name "Toybox" is meant to imply.

Thanks,
sj
