Bell 103 Protocol
Bell 103 protocol is for 300 bps full-duplex connections. The features
described in this guide apply to Bell 103 operation except that your
modem does not support:
• Digital (loop 1A) and analog (V.54 loop 3) loopback.
• LAPM connections.
6.4.1 Protocol Configuration Command Settings
When you send an AT string to the modem, it adjusts modem-port speed
automatically to match the AT speed. Use %G1 to disable this feature.
With %G1 set, you can change the modem speed with %Bn (where n is
the new modem speed) and %Fn.
This section lists settings to configure the modem for each mode and
protocol. Modem connection speeds are in parentheses.
Table 6-3 Configuring the Modem with %F0 Set
NOTE
When your modem establishes a reliable Bell 103 connection,
it displays CONNECT 103/REL - MNP. For a normal or direct
Bell 103 connection, the message is CONNECT.
