Re: GTO CP3 connection problem via COM port in Windows 10
Oh well, I guess it shall remain a mystery then.... Like I say it is just a nuisance, as a second attempt at connectingOne possibility is that it could be the COM port on your computer has garbage in the send or receive buffers.
You could try seeing if there is a specific COM port driver for your computer. Also you could try replacing or adding another COM port adapter to see if the problem goes away.
