If MT has succeeded in establishing a logical link between application protocols and external interface, it will send
CONNECT message to the TE. Otherwise, the NO CARRIER response will be returned.
If the CONNECT response is received, TE can start sending <proto> or upper layer frames.
The connection shall always return for <proto> mode when the protocol session is ended. When the MT receives a
disconnect request from its peer entity, it will process it and send OK response to the TE indicating its capability for
receiving new AT commands. Since <proto> or upper layers can be accessed in other ways, TA must have pre-
knowledge of the fact that connection is initiated with AT+CPROT command. This means that switch to <proto>
mode must include some sort of notification to the protocol entity.
This command can be aborted by sending a <proto> or upper layer disconnection frame. In that case, MT will return
in command mode by sending the OK response.
Refer subclause 9.2 for possible <err> values.
Test command returns values supported as a compound value.

Phone Activity Status (+CPAS) is a general command used to detect the presence of the MT, if there is an incoming
call, or if there is a call in progress. This command should be used before trying to operate the MT from the TE. Note
