Yeah, if a COM port disappears, LOGic definitely complains. You can test this by yanking the plug on a USB interface. LOGic must be receiving a data packet of a valid length with the proper headers etc but with 0 in the frequency data area. I know it sounds far-fetched. What radio do you have? On some radios, there is minimal header and footer data with the packets so if it were sending anything, LOGic would be happy.
Quote:Is LOGic polling microHAM for the frequency data?
It depends on the radio. What rig do you have. Icoms & Kenwoods, generally no. Yaesu, yes. Actually, LOGIc just talks to the Windows .NET COM port interface. It doesn't know or care about MicroHam per se.
Quote:What would happen if you programmed LOGic to maintain the last valid data, as long as there were active comms?
If you get zeros, do they zeros go away when you QSY?
Tnx & 73,
