I have a number of communication programs that can talk to serial ports, 
TCP, etc. As far as I know they were all free. I have an olde DSP2232 
TNC that I used in the 'old' days when I was the South East area 
Satgate. It has full duplex packet capabilities among others. Been using 
it lately for QRP (5 watts) RTTY. The programs I have are:

HyperterminalPrivatge, K95g (Kermit), Putty, Realterm, TeraTerm, and 
Termite V3.2. Each has their own advantages. I use TeraTerm the most. I 
like that it can have cut and paste data inserted i n the window. I 
believe it also allows you to send a file as well.

Most of them are a matter of taste. K95 has a lot of built-ins but a bit 
harder to use.
