Run the communication software provided with the
modem. Put the computer in terminal emulation
mode, so that the computer functions as a terminal.
To check whether your computer and modem are
communicating properly, either enter "AT" and
carriage return. The modem should respond by
displaying the letters "OK" one the computer
screen. If the modem does not respond or if the
software can not enter terminal mode, the
communication port setting of modem may conflict
with that of another serial device in your system. In
this case, you will need to adjust the settings to
different one.
If the "AT" is not displayed when you type it, the
local echo function may be off. To turn it back on,
type "ATE1" and carriage return.
If double characters appear on the screen, both
your modem and software are set to local echo on;
in this case disable the local echo function in your
software application, or you can type "ATE0" and
carriage return to turn the modem's local echo off.
If you suspect a problem with modem or the
telephone line after installation, disconnect the
modem until you determine the source of the
problem.
