Modem communications
The following describes important parameters and modem settings required for high speed modem configuration (9600
bps and 19200 bps) to the 3GS Controller
The commands detailed refer specifically to Multitech modems. For other modem types, please refer to the manufacturer
manual for equivalent settings.
The following tables show parameters to be set for modem communication (in this case Multitech modem) with Panelman/
ED2000:

DTR Signal
The PC will normally provide its modem with Data Terminal Ready

The panel doesn’t provide DTR, so its modem must be configured to
ignore this signal.

V.32 Terbo Tones
