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.
