[Flexradio] RemAUD PTT with SmartSDR Help

[Steve Sterling]

I'm trying to get the PTT function of RemAud (Remote Audio app by DF3CB)
to actually work with SmartSDR for remote operations. No problem getting
the RemAud client and servers installed on their respective computers
and talking via port 4000. No problem connecting and configuring the
audio through DAX-- audio is being passed when I connect up.

RemAud server (that runs on the SmartSDR host CPU) uses either DTR or
RTS for PTT function. From the remote client, I can toggle PTT, and the
server acknowledges. Should be a straight forward SmartSDR CAT setup
according to the manual. Add Port; port protocol PTT; port type Serial;
Serial Port: FlexVSP (set up with a com114-com14) pair; vfo slice A;
tell it to use RTS in both SmartSDR Cat and the RemAud server); change
polarity if it is backwards; auto switch tx slice enabled.

But it don't work. RemAud indicates it connects successfully to the com
port. I've tried using both RTS and DTR, including making both active
(both RemAud and SmartSDR CAT can use either).

HELP-- has anyone made RemAud work with SmartSDR? I had no trouble
using it with PowerSDR & DDUtil.

Thanks in advance for any help
