I am absolutely NOT that keen programmer(grin)...

I wonder, might the answer be some kind of external hardware device?  I'm 
thinking "Winkey for FSK", possibly implemented on Arduino hardware.  Actually, 
wouldn't that be fairly simple, since the external device doesn't have to worry 
about receiving?  (that can be done in DSP on the Linux host)  You'd just feed 
ASCII characters to the external hardware over a RS-232 or USB port; the 
hardware (OK, firmware) would map to Baudot & shift a digital output port up & 
down with appropriate timing.
