Oh well, I guess it shall remain a mystery then.... Like I say it is just a nuisance, as a second attempt at connecting
will work. I was just hoping that it is some software setting that is causing this problem.

One 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.

Subject: Re: [ap-gto] GTO CP3 connection problem via COM port in Windows 10

AP Jog fails to connect even in normal mode, if launched after a fresh reboot. And as it is a fresh reboot, there is
nothing trying to access COM1.

The reason why I run APJog in administrator mode, is so that later on when I run Voyager, which must be in
admin mode, the same driver instance will be used. Otherwise, there will be two instances of drivers and they
don't play nicely together -- been there, done that.
