I opened a support ticket (after hours) but I'm hoping someone knows a work-around.
I was setting up my remote system. I was rehearsing it at the shack so I had everything plugged in. Once I installed the remoterig's drivers (N.B. remoterig is a company that has devices that enable remote operation -- I had both at the shack at once to "rehearse" things), CAT has never been the same. I "lost" my usual COM4 for CAT and it never came back. I uninstalled the remoterig software and its drivers. No help. I uninstalled and reinstalled SmartSDR 1.3.8. No help. Windows does not "see" the drivers, even when I use a mode I found in the internet that is supposed to identify hidden devices.
When I do things like the FA; command under SmartCAT's test, I get a correct response. So, the basic flow is there. What it seems like is that somehow, SmartCAT does not "register" the port anymore, so programs like FliDigi and MixW2 cannot find it. I know that things are basically sound elsewhere, because I have other devices (e.g. serial emulation) and I can access and contact them just fine. Configuring a PTT port also fails. Basically, it's like SmartCAT knows it is there, SmartSDR (or the part running on the rig anyway) seems to respond to it. But no applications are able to "see" or open the port. So either it is not there (which is what Device Manager kinda sorta tells me by not listing it) or else it is somehow "jammed" open by some other program. But, I have rebooted and rebooted, and kept it pretty basic thereafter, so it's hard to grasp who that might be (the message says "not there or in use" which is why I mention this). I think it really just isn't there.Anyone have any idea what to do?
