I use SparkSDR with my Hermes Lite 2 SDR. Spark SDR uses RigCtld for CAT communication, so it was great to hear that VarAC now can also use RigCtld. Unfortunately I cannot get it to work. The local host and port are set correctly in VarAC (I know this as I get no error when testing. If the port is changed then an error is displayed in VarAC). The log files in SparkSDR show that VarAC is connecting and disconnecting but no commands are received by SparkSDR. I also get unhandled exceptions when opening VarAC. Deleting the .ini file enables the program to run again, but then all details have to be re-entered. This has happened multiple times. Here is an extract from the .ini file showing the settings. This .ini file has something that causes the unhandled exception issue.

What is causing the unhandled exceptions? Thanks Dave M0WID

I would like to use the excellent SparkSDR software with VarAC. Spark SDR uses Hamlib RigCTL as CAT interface. This is TCP based, using computer name and port, so no messing around with virtual com ports. Would it be possible to add support for this in VaraC? Thanks Dave M0WID
