i have wsjtx running well on my dx10 using virtual comm port 5. i am trying to setup varac. i have it all properly configured i believe, with comm port 5, but when i go to test the sound card, or test PTT, using CAT, it fails with an error "the comm port can't be accessed" and the help popup suggests something else has control of the comm port. wsjtx is closed. i look for processes that might be using comm5; no luck. so i don't know how to release this port. another confusing thing is, i also have omni-rig available and it too does nothing.
i'm stuck. i'm so close but so far. can anyone help guide me on this? thanks in advance, 73, tom wa2uvc
