3.22 AT+CPAS Phone Activity Status
Returns the activity status <pas> of the ME. It can be used to interrogate
the ME before requesting action from the phone.
When the command is executed without the <mode> argument, the
command returns <pas>-values from 0 to 128 (for supported values se
table 1 below). When, on the other hand, the command is executed with
the <mode> argument set to 1, the command may return Ericsson
specific <pas> values from 129 to 255 (for supported values see the
table below).
Test command returns values supported by the ME as a compound
value: refer to GSM 07.07.
