AT commands supported.

Initiate Communication
At this point, the dsPIC30F Soft Modem is ready to establish a dial connection with
another modem.
1. Initiate dialing with the following AT command:
ATD< dial string >
where < dial string > indicates the telephone number of the remote soft modem.
By default, ‘auto answer after one ring’ is enabled. The remote soft modem
answers the call after one ring and connects in V.22bis and V.42 (LAPM) Mode.
ITU-T Recommendation V.42 contains a High Level Data Link Control (HDLC)
protocol referred to as Link Access Procedure for Modems (LAPM) and defines
error-correcting protocols for modems The following result codes are displayed
on both the Hyper Terminals upon a successful connection.

You should hear the call negotiation and training sequence on the call progress
speaker. If you are using a standard reference modem on one terminal, the con-
nection message transmitted and displayed on the PC may be slightly different
but should present this same basic information. See Section 6.8.6 “Response
connection message provided by a USR 5686E type modem.
2. With the two modems connected, test data transfer by typing information on one
terminal and verifying that the same data is displayed on the other terminal.
3. Test file transfer by creating a brief text file and using following file transfer
options on the HyperTerminal.
HyperTerminal>Transfer>Send Text File
HyperTerminal>Transfer>Capture File
4. Repeat the test procedure for the other modulation protocols by executing the
following AT commands:
