What rig control software are you using?
Many, many "heritage" programs use serial port access methods that don't
comply with the latest and greatest Windows methods. Not just trying to hit
the hardware directly, but even trying to open "COMx:" doesn't work
reliably. And, working your way through all the Windows API calls to make
serial ports work is a royal pain.
