      Joe, All,
      The keying methods for WINMOR and V4 are similar. There are several possible methods.... any will work when set up correctly.
      1) VOX or VOX type keying.  The virtual TNC adds a longer leader to allow the transmitter VOX (or in the case of a sound activated PTT like on the SignaLink USB or similar interfaces) to key the transmitter.  If using the SignaLink  you MUST have the PTT output wired to the radio and you MUST keep the DLY control fully CCW. For Transmitter VOX you should have the VOX hold or delay set to minimum.
      2) Using a the DTR or RTS signals of a dedicated serial port.  This may have to be level shifted or go through a relay to key the transmitter.
      3) On those radios that support “CAT PTT” the software will issue a PTT ON/OFF command to the software.
      The Help should elaborate on these methods and how to set them up.
      The acid test is to look at the T>R  latency as measured when calling for a connection. No matter which method you use the latency must be < 250 ms.

      Joe. I observed on the RMS Express using Winmor, and on RMS Trimode. Did not so far check on myself on V4. We need inventor of both, Rick, chiming in.

      I believe the soundcard and way of keying is part of the issue.

      (Sound Blaster) sound card in my WinXP PC. With this same system, I get different results with Winmor than I do with V4 when issuing the Morse-code ID. I find no parameter that would control the ID behavior in the .ini files for RMS Express/Winmor nor V4.

      many others are in FSK. In the V4 modem my ID is in FSK. Can I set it to CW instead? I looked in the .ini file but saw no option for that.
