Proprietary AT Command Set
AUTO-MODE DETECTION | |
Type: | Configuration |
Format: | AT [cmds] Nn [cmds] |
Description: | Selects various options for the automatic detection and negotiation of protocols during the handshake process if the modem is communicating with a remote modem of dissimilar speed. |
Command | Function |
N0 | When originating or answering; handshake only at DTE to modem rate |
í N1 | When originating or answering; handshake at DTE to modem rate. Modem can shift to a lower speed if necessary |
COMMUNICATION PROTOCOLS | |
Type: | Configuration |
Format: | AT [cmds] Bn [cmds] |
Description: | Selects the communication protocol for data calls |
Note: The B command allows the simultaneous selection of more than one suffix, enabling multiple protocols. | |
Command | Protocol |
B0 | ITU-T V.22 at 300 or 1200bps |
B1 | Bell 212A at 300 or 1200bps |
B2 | V.23 at 75bps transmit, 1200bps receive in originate mode; 1200bps transmit, 75bps receive in answer mode |
