Figure 1-3. Completed modem installation
If you connected the modem to a computer, place the computer into terminal mode and
complete the configuration information required by the software. Refer to your software
manual to find out which commands to use.
Then use the following procedure to verify your modem connections:
1. Type AT and press the Enter key. The RD and TD LEDs flash on the modem front
panel. If your system is operating properly, your modem sends an OK response to your
computer screen and wait for your next command.
If the LEDs did not FLASH, or if you did not receive a response, make sure your computer
is sending commands to your modem at a speed of 300, 1200, 2400, 9600, 19200, 38400,
57600 or 115200bps. If this does not solve your problem, contact your computer dealer.
2. Use your communication software to prepare your computer to dial a call. Then type
ATD x phone number, where x is either T for Touch-Tone dialing or P for Pulse dialing
and phone number is the telephone number that your modem is using
For example, if your modem is connected to the telephone line 555-2121 and Touch-Tone
dialing is supported in your calling area, type ATDT 555 2121
3. Press the Enter key. You should receive a BUSY response and you should hear the
busy signal through the modem speaker because the modem is calling itself.
Your modem is now ready for operation. Refer to the manual that came with your
communication software to begin communication. If you will be communicating directly
with your modem, or if you want to find out more about the modem's operation, proceed to
use's manual.
