Dialing a Call Using the AT Command Processor

To dial a number using the DTE terminal and AT commands type ATD and the telephone number on one line and press Enter.

ATD5551212

When the dialing process begins, the front panel reads Dialing 5551212. If the call is successful, Connect is displayed on the front panel, followed by the rate adaption protocol in use and the bit rate. If the call is not successful, the front panel displays Disconnect followed by Ready. At this point the unit is ready for another call. The status buffer can be examined to find the reason for an unsuccessful call.
