+CNMA – New Message Acknowledgement
2 - It has been necessary to take the following decision to get over any incoherence
problem, due to the possibility to have contemporaneous different settings of
parameter <mt> and <ds> of the +CNMI command in different sessions (see
#PORTCFG and +CMUX): only the <mt> and <ds> setting for session “0” are
considered as valid to decide if +CNMA acknowledgment is expected or not.
