Cellular Phone Drivers

The data interface to cellular phones differs between manufacturers and models and
requires a unique cellular phone driver for each phone or group of phones. Therefore the
particular phone driver needs to be downloaded from the PC into the modem's RAM
before the modem can be used directly with the cellular phone. If a driver is not loaded
the modem will operate as a normal landline modem.

Cellular Commands

^C2 - Download Cellular Phone Driver

The ^C2 command initiates the cellular phone driver download function. Upon receipt of
the command, the modem issues the "OK" message. The user then performs an ASCII
download of the driver (in .S37 format) from the host to the modem, typically using a
communications software package (with transmit pacing turned off).
