COURIER HIGH SPEED MODEMS
d. Be sure that DIP switches 1 and 6 are set ON or OFF
according to your terminal or software requirements. The
table in Appendix B explains each function, and you may
also need to review the quick-configuration guide or your
terminal or communications software documentation.
e.
f.
g.
The Quad switch on the right should be in the OFF position.
If you set DIP switch 8 OFF, for Dumb mode, reset the
modem to Smart mode: set DIP switch 8 ON, power off the
modem, and power it on again.
DIP
switch 3 controls the display of the modem's result
codes, including the OK result. The modem is shipped with
DIP switch 3 ON, enabling the result codes. If DIP switch 3
is OFF, reset it to
the ON position. Then initiate the new
switch setting with the following reset command.
ATZ <Enter>
5. A final check of the modem is to see that it gets a dial tone.
Type the following manual Dial command:
ATD <Enter>
On receipt of the command, the modem goes off hook and
waits for a dial tone. The OH indicator lights, and you'll
hear the dial tone from the modem's speaker. To cancel the
operation, press any key.
If you don't hear the dial tone, first increase the volume by
sliding the volume control switch towards the front of the
modem. If that doesn't work, check to see that the phone
cable from the wall jack is connected to the correct jack on
the modem. The correct connection is to the jack identified
by the wall jack icon on the bottom label of the modem case,
not the phone icon. If necessary, reconnect the phone cable
correctly.
Then try the manual Dial command again, ATD
<Enter>.
