Running new version of VarAC with an Icom IC-7300. Sometimes, CAT PTT drop signal is not properly received by the 7300 which stays in keyed mode with no audio input.

Since doing this to the 7300 CAT config, I haven't had a problem:
CI-V address - 94h
CI-V Transceive - Off
CI-V USB Port - Unlink from REMOTE
CI-V USB Baud Rate - 19,200. I use 115,200, but use 19,200 for starters as that is what flrig defaults to. Response will be a bit quicker with higher rates, but it will do well at 19,200 also.
CI-V USB Echo Back – On
which is from this:

This is usually due to lack of CPU resources on the PC at the moment the PTT command was sent. As VarAC fires a lot of CAT commands due to the nature of the mode.
questions:
1. Does it happens upon first connection with a station ?
2. Do you have limited CPU resoruces on your PC ?
