lthough the modem’s default option settings are
suitable for most PC computers, a default option
setting can cause problems if it is incorrect for
your application. You can resolve many problems by
first checking the following settings on your computer

DTE:
q
Data and parity (7/odd, 7/even, or 8/none)
q
Terminal speed (115200 or 57600 or 38400)
q
Correct COM port is selected (Z34-SL - DTR LED
on)
q
Local echo setting on PC terminal is set to off.
q
Hardware flow control (RTS/CTS) is on for both
PC/terminal and modem.
q
Make sure the modem card is fully inserted in
the expansion slot (Z34-PL).
q
Make sure a serial model cable connects your
PC/terminal to the modem.

Make sure the modem has the RTS and DTR
LED's on.
