COM Port problem

Post by GM1YME » Wed Feb 26, 2020 11:38 pm

Have installed latest OpenGD77 CPS on a Windows 10 machine. The new driver appeared to install OK at this point.

I can read the codeplug from the radio (which has not yet been reflashed to OpenGD77 firmware) from the Program Menu. So presumably the cable is working OK.

However, when trying to back up EEPROM from the Extras/OpenGD77 support Menu no COM Port is shown and I get the undernoted crash if I try to select the empty box. I can't read the Codeplug from this menu either.

Looking at the COM Ports in Device Manager (Showing Hidden Devices), there are 4 entries:

Opticon USB Code Reader(1D) (COM3)
Opticon USB Code Reader(1D) (COM4)
USB-SERIAL CH340(COM5)
USB-SERIAL CH340(COM7)

Where do I go from here?

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

The Com port is part of the openGD77 firmware. So it won’t be available if you have not updated the firmware.

That's done the trick!

Wanted to back up everything before reflashing the set....
