The SET command is used to attach the MT to, or detach the MT from the GPRS
service. After the command has completed, the MT remains in V.250 command state.
If the MT is already in the requested state, the command is ignored and the OK
response is returned. If the request is not completed, the command returns ERROR or
+CME ERROR. The external error response is enabled via +CMEE command.
Any active PDP contexts will be automatically deactivated when the attachment state
changes to detached.
The READ command returns the current GPRS service state.
