I have a BC346XT and am trying to get it to communicate with the ARC-XT software. The cable is secure, radio is on, baud rate matches between software and radio. I've tried multiple combinations of baud rates and all the comports I have. The troubleshooting instructions for the software don't help and their tech support is kind of lame as well. I just don't know what else to do. Any one else had and solved a problem like this? I suppose the cable could be bad but I have a sneaking suspicion that I just need to get one or two software settings tweaked and I'll be good.
