Like any modem, your Multi-Tech modem operates only under the control of a communications program, such
as the communications program included with your modem. It also operates under other general-purpose data
communication programs, such as Windows Terminal and HyperTerminal. For information on how to use the
modem with the communications program of your choice, please refer to the documentation provided with the
data communications program.
An experienced modem user can configure the program’s software to change the way the software interacts with
a modem and configure the modem to change the way it operates.
