// Description:
// The execution 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.25ter command state.
// If the MT is already in the requested state, the command is ignored and the OK
// response is returned. If the requested state cannot be achieved, an ERROR or +CME
// ERROR response is returned. Extended error responses are enabled by the +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.
// The test command is used for requesting information on the supported GPRS service
// states.
// +CGATT= [<state>]
// <state>: indicates the state of GPRS attachment
// 0 ?detached
// 1 ?attached
// Other values are reserved and will result in an ERROR response to the
// execution command.
