 Well, using the beauty or the Unix device paradigm, you can open /dev/ttyS1
to do IO to the serial port.  (S0 is DOS COM1, S1 is DOS COM2, etc.)

 I don't know if you can do ioctl()s on it from java, so you might have to
do something ugly like system( "stty crtscts 115200 < /dev/ttyS1" );  to
change the serial port setting from java.  (system() is C, but there's a
java equivalent somewhere.  System.run() or something?)
