What mode do you want?
assuming RTTY, then  MMTTY will give a digital output on the COM port, which you can clamp to 0 / 5V

Hello the list,
Does anyone know an easy way to generate 5v TTL signals to drive a synth fsk input?

Fair enough - several audio analysis/test  progs have the facility including Alberto's after my request a while back.
 
Hadn't realised Spectrum lab had Digimode facilities, but I don't use that package very often.   Find it too complicated to use when all I want at any time may be a spectrum analyser, or a data decoder, or a tone generator.   Easier to call-up a different custom package for each one, and run several in parallel if necessary.

Andy,

If memory serves, JASON and Spectrum Laboratory's Digimode Terminal have I/Q outputs.
