A few months back, a list member recommended RemAud (Remote Audio), a "made for ham ssb remote audio" and ptt software agent for remote audio and ptt tool. Better audio than Skype, Teamviewer, etc and the ability to key the ptt. (Yes, RemAud has a PTT timeout timer just in case).

I finally had the time to install, but am having trouble getting the PTT function to work.

I use VSPManager (thanks Steve Nance) as my virtual serial port tool. When I set it up, I used virtual ports 9-19 (created by VSPManager) to connect to DIRECTLY to the PowerSDR DTR/RTS PTT signalling. The RemAud tool only offers DTR/RTS method of PTT. RemAud has no capability of using the Kenwood style serial string commands that I use via ddUtil for FLDigi, amp control, rotor control, K9DUR's VoiceKeyer, etc.

Problem: as soon as enable the CAT/PTT function in PowerSDR it throws my Flex 5K into transmit. As if it is seeing DTR and RTS always in the transmit position, irrespective of what RemAud is setting via DTR or RTS. VSPManager shows both apps (PowerSDR and RemAud) successfully connecting to their respective ports.

Has anyone successfully connected the PTT function from RemAud to PowerSDR? Does VSPManager handle DTR/RTS signalling?
