While I don't have a Pegasus, I DO operate PSK 31 and have found that VOX is
NOT reliable because the narrow band of frequencies you transmit in PSK 31
MAY or MAY NOT key your transmitter using VOX. My VOX circuit seems to be OK
at certain PSK audio frequencies but not others (no good usually above 1200
Hz). This is not a problem using regular voice audio in VOX as the human
voice has a complex audio band of frequencies. Another way to do it is to
shift your RF frequency to have the decoded audio fall in your "sweet spot"
audio frequencies.
To be honest, I use manual PTT with my footswitch or mic PTT switch. I avoid
using another serial port this way.
Ya need a serial port for EVERTHING nowadays!
A HAM's computer should come with 6 ports as standard.

Thanks for reply. As far as software, I was going to use WinPSK 2.09, but
that seemed rather inflexible so I just downloaded Stream v. .9.
What the Rascal claims to be looking for from the the serial port is the T/R
command, so that it does not have to rely on VOX which is not recommended.
That is all..either a DTR or RTS signal.
Thanks,
