[aprssig] ARISS Satgates

[Chuck Kimball]

Quick question as someone else has probably already researched it.

It there a good software package that will handle multiple TNCs on 
multiple serial ports?

I'm getting ready to set up a I-Gate when I get home, and if I could do 
it on the same machine
to handle a TNC on 144.390, another (maybe 9612) with a 1200 baud port 
on 145.800, and
the other TNC port on a 435 for echo or one of the other sats...   Would 
seem to be much easier
than  running several computers. 

Thanks
