[FADCA] Points of Clarification

Chuck:

It is possible The Light is coming on in Deltona....

My question is hardware related:

To pull off this "LINUX FPAC box" does that require running FPAC/LINUX in
the computer AND having some  hardware interface"box" other than comports
out to TNCs, radios, phone lines, etc?

Rick KN6KB - see below - does this work for your SMS stuff where we have an
internet connection at the "LINUX FPAC box"?

Man, we may be getting there...
