Maybe I made some mistake in experiment.
Looks like on /dev/ttyUSB4 doing AT+COPS? or AT+CREG? won't work while on /dev/gsmtty1 they work. So /dev/ttyUSB4 seems to a subset of what's available over n_gsm on ch1. Anyways, good to hear that /dev/ttyUSB4 can be used to debug voice calls :) > Thanks for hints, it would not be bad to get gps working. But .. voice > calls. Those are important :-). Yup, please keep us posted :) Meanwhile, I'll slowly continue getting the n_gsm stuff working. Tony
