Testing Your Modem
4-3
Issue 3 October 1995
4. Test the modem connection by typing AT and then
pressing Enter.
The modem should respond with an OK. This indicates that
your modem and computer are communicating correctly.
Now test the connection between your modem and the
telephone line by following the procedures in the
Dial-Line
Connection Test
section.
If an OK does not appear, verify that the modem and
communications software are configured for the same COM
port, and repeat this step. (For the external modem, the TR
LED should be ON.)
If the modem still does not respond, refer to Chapter 6,
Troubleshooting , for additional tips.
Dial-Line Connection Test
The following procedures test the connection of your modem to
the dial telephone line. Step 1 verifies the dial-line connection,
and Step 2 allows you to dial the AT&T BBS and log on as a new
user.
If you are using Pulse (rotary) dialing, type ATDP instead of the
ATDT shown in this chapter. If you need to dial some other
number in addition to or instead of 1 before the area code, or
you are calling from the 813 area code, change your dial strings
appropriately. Your modem must dial the same way you would
dial using your telephone, with the same prefixes and pauses for
dial tone. See the Dial command in Appendix B for information
about special dialing modifiers you can insert in a dial string.
1. Enter the following dial string:
TYPE: ATDT 1813-532-5254;h
PRESS: Enter
The dial string consists of the dial command (ATD), the Tone
dial modifier (T), the telephone number (spaces and dashes
are not required, and are only used to enhance readability),
semicolon (;) modifier which allows additional commands to
be added to a single line, and the hang up (h) command
which disconnects the call.
