Java-Pactor Communication

I managed to establish the communication between Java code on the laptop and the SCS Pactor modem that is connected to the SSB, I've written a simple and basic character mode console that works on both Linux and Windows.

I will create a Google Code project, but in short, here are the parameters to set to the serial port:

Baud Rate: 57600 bps
Data bits: 8
Stop bits: 1
parity   : none
RTS/CTS in   [ ]
RTS/CTS out  [x]
XON/XOFF in  [ ]
XON/XOFF out [ ]
RTS : [x]
CTS : [ ]
DSR : [ ]
CD  : [ ]
DTR : [x]
RI  : [ ]

Notice the RTS/CTS in, that remains unchecked.
I want to be able to read Navtex data, and receive faxes in the future. That would imply some signal processing (FFT and this kind of things). That sounds interesting...
