COURIER HIGH SPEED MODEMS
c.Make sure your software has put the computer in Terminal mode, so that you can send the modem commands. Then review Step 4, on the previous page.
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 your terminal or communications software documentation.
e.If you set DIP switch 8 OFF, for Dumb mode, reset the modem to Smart mode: set DIP switch 8 to ON.
f.The modem is shipped with DIP switch 3 ON, enabling the result codes. If DIP switch 3 is OFF, set it to the ON position. Then initiate the new switch setting with the following reset command:
ATZ <Enter>
5.As a final check, make sure the modem gets a dial tone. Type the following Dial command:
ATD <Enter>
On receipt of the command, the modem goes off hook and waits for a dial tone. The OH indicator lights up, and you'll hear the dial tone from the modem's speaker. To cancel the operation, press any key.
Troubleshooting
If you don't hear the dial tone, first increase the volume by using the L command. 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. If necessary, reconnect the phone cable correctly. Then try the Dial command again, ATD <Enter>.
