// Description:
// The set command controls the presentation of an unsolicited result code +CGREG:
// <stat> when <n>=1 and there is a change in the MT's GPRS network registration
// status, or code +CGREG: <stat>[,<lac>,<ci>] when <n>=2 and there is a change of the
// network cell.
// The read command returns the status of result code presentation and an integer <stat>
// which shows whether the network has currently indicated the registration of the MT.
// Location information elements <lac> and <ci> are returned only when <n>=2 and MT
// is registered in the network.
// Defined values
// <n>:
//  0 disable network registration unsolicited result code
//  1 enable network registration unsolicited result code +CGREG: <stat>
//  2 enable network registration and location information unsolicited result code
// +CGREG: <stat>[,<lac>,<ci>]
// <stat>:
//  0 not registered, ME is not currently searching a new operator to register to
//  1 registered, home network
//  2 not registered, but ME is currently searching a new operator to register to
//  3 registration denied
//  4 unknown
//  5 registered, roaming
// <lac>:
//  string type; two byte location area code in hexadecimal format.
// <ci>:
//  string type; two byte cell ID in hexadecimal format
