Com Port no longer available on AT Mega GT2560
Posted: Tue Apr 14, 2020 3:21 pm
Hi,
I have been using my I3 Pro C for two years connecting through COM3 port with no problems using a Windows 10 Laptop.
I tried using my new iMac and after initially connecting, the COM port disappeared. I thought it was a Mac problem and tried loading a new driver an other configuration settings.
I plugged in my Windows Laptop today and the COM3 port no longer exists. I can't connect to the printer at all. Is there any way that I can test whether to GT2560 board is dead and I need to replace. Or are there other options?
I would appreciate any advice
