ii) DTMF callback connection uses a special GSM modem (Sony Ericsson Modem
GM29) which uses a digital number.
The PowerMax Remote Programmer dials the GSM unit via analog communication,
but, instead of sending data it uses DTMF tones. The PowerMax 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.
