Response
TA returns messages with status value <stat> from message storage <mem1> to the TE. If status of
the message is 'received unread', status in the storage changes to 'received read'.
Note: if the selected <mem1> can contain different types of SMs (e.g. SMS-DELIVERs, SMS-SUB-
MITs, SMS-STATUS-REPORTs and SMS-COMMANDs), the response may be a mix of the respon-
ses of different SM types. TE application can recognize the response format by examining the third
response parameter.
