my 1st post here.
I have serial over OTG between Win10 PC and Zero working, fine as long as I use it for console login. (serial-getty@/dev/ttyGS0.
If I stop the getty service, No usb/com port is opened @ PC side, when I plug it. I still see the /dev/ttyGS0 on the PI (stty -F/dev/ttyGS0) but apparently the device is not opened to the external world. I would expect that any send command to the device would open it,
e.g. ls > /dev/ttyGS0,
but nothing opens at the Win10 PC. What does getty do, so that the PC discovers the new usb serial connection and
