That meant that the port had to be closed and re-opened after every context activation / deactivation. This is normally turned off with AT&C0. Re-opening the modem port is actually not trivial. Search the archives / git, there have been previous attempts at doing this which were abandoned. The easiest solution will be to figure out why AT&C0 doesn't work.
