Modem Setup (for Modem
→
Other)
If you prefer to use another modem than the standard models listed in
the Setup menu (MultiTech, Elsa), you will have to enter a few
parameters required for communication between the MAC 1200/1200 ST
and the modem.
For the AT commands which your modem understands, please refer to
the modem user instructions. Three command sequences have to be
entered, each of which defines a specific modem operating state.
1. The modem is initialized (init string).
2. A communication link is established (dial string).
3. The communication is terminated (hangup string).
These three strings are entered in the modem setup menu. (See Chapter
3,
“Connecting Peripheral Equipment” )
The example below shows the command strings for the MultiTech ZDX
modem.
