Check telephone line with a regular phone to
make sure dialtone is present.
If you encounter basic communication problems (cannot
dial, answer, or connect), run through the
troubleshooting procedures and attempt to isolate the
source of your trouble.
Basic Communication Problems
The modem comes with PC software that will help you
to troubleshoot communication problems. Install the
SuperVoice software on your computer. If you do not
have a Windows PC, use another compatible
communications package that has a terminal
emulation mode (TTY or VT100), which is sometimes
called a direct connect mode.
To start troubleshooting, double click on the
SuperTerminal icon and set up the
Setting|Communication parameters. Set Baud Rate to
57600, Init string #1 to AT&F&C1, COM Port to the
correct one, Data Bits to 8, Parity to none, Stop bits to
one, and Flow Control to hardware. Now click on OK.
Type AT<ENTER> . The AT should be echoed back to the
DTE screen, followed by OK from the modem. If these
characters don’t appear on your screen, try a different
COM Port setting and repeat the instructions above.
NOTE: On the Z34-SL, the DTR LED will be on if
the correct comport is selected.
If still unsuccessful, follow the procedures described
below to determine the problem.
