detected. This is compatible with seven data bits, no parity, two stop bits. Seven data bits, no parity, one stop bit may be
forced by sending AT\T17\B1.

Character length will be automatically set in autobaud mode
6N1—six data bits, no parity, one stop bit, one start bit, eight bits total (\N0 only)
7N1—seven data bits, no parity, one stop bit, one start bit, nine bits total (\N0 only)
7P1—seven data bits, parity optioned by \P, one stop bit, one start bit, 10 bits total
8N1—eight data bits, no parity, one stop bit, one start bit, 10 bits total
8P1—eight data bits, parity optioned by \P, one stop bit, one start bit, 11 bits total (\N0 only)
8X1—eight data bits, one escape bit, one stop bit, one start bit, 11 bits total (enables ninth-bit
escape mode)
Asynchronous protocol
Wire mode (no error correction, no compression)
MNP reliable mode. The Si2457/34/15/04 attempts to connect with the MNP protocol. If unsuccess-
ful, the call is dropped.
V.42 auto-reliable—The Si2457/34/15/04 attempts to connect with the V.42 protocol. If unsuc-
cessful, the MNP protocol is attempted. If unsuccessful, wire mode is attempted.
V.42 (LAPM) reliable mode (or drop call)—Same as \N3 except that the Si2457/34/15/04 drops the
call instead of connecting in MNP or wire mode.
V.42 and MNP reliable mode—The Si2457/34/15/04 attempts to connect with V.42. If unsuccessful,
MNP is attempted. If MNP us unsuccessful, the call is dropped.
Parity type will be automatically set in autobaud mode

Modem-to-DTE flow control
Disable all flow control—This may only be used if the DTE speed and the VF speed are guaranteed
to match throughout the call.
Use CTS only
