i) The user needs to obtain a digital number for the GSM unit. The

Remote Programmer is then able to connect to the GSM unit via

digital communication (at a baud rate speed of 9600).

ii) DTMF callback connection uses a special GSM modem (Sony

Ericsson Modem GM29) which uses a digital number.

The Remote Programmer dials the GSM unit via analog

communication, but, instead of sending data it uses DTMF tones. The

Remote Programmer sends the download code (numeric, 0-9) and the

phone number (consisting of the Sony Ericsson Modem digital

number). After disconnection, the GSM unit calls back the Sony

Ericsson Modem (via digital communication at 9600 baud rate).

• The Comm port field becomes disabled and the field value is the

communications port where the modem is connected.

• The Baud rate field displays 300 (analog communication) or 9600 (digital

communication), the baud rate used for telephone modem connection.

• The Parity and the Stop bits fields do not change.
