Hi, am a novice trying to get 2 devices, one on com1 and one on com2 to work simultanously. Each have a separte software. When both are run togther, device 1 on com port1 get "Run time error 8005, port already open" error and crash out. I have checked and both don't have conflicting IRQ. Please advised what could be the possible causes.
Thank you very much.
