I have a ham radio connected to a computer via COM4. Under this arrangement, I can control the radio (frequency, band, mode, etc.) using a single control application configured for COM4. But I want to control the radio using two separate applications at the same time.
I set up Virtual Serial Driver Pro to split COM4 between virtual COM ports 10 and 11 with one of the two applications set up for COM10 and the other for COM11. I thought this would work, but it doesn't.
Note that the application connected to the port that I set up for "Set main" does indeed control the radio, but the other application does not, in fact, the other application has a hard time connecting, and after it does, it soon disconnects.
How can I get both applications to control the radio?
