2 * This program is a debug and development aid - it uses the AT+CMGW command
3 * in PDU mode to write messages into SIM or ME SMS storage, simulating
4 * arbitrary received or sent messages. This trick may come in useful
5 * in the development and testing of SMS handling in phone handset UI firmware.
