Character length
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 Si2456/33/14 attempts to connect with MNP2-4 error correction. If unsuc-
cessful, the call is dropped.
V.42 auto-reliable—The Si2456/33/14 attempts to connect with data compression and error
correction (V42bis and V.42). If unsuccessful, V.42 only is attempted. If unsuccessful, wire
mode is attempted.
V.42 (LAPM) reliable mode (or drop call)—Same as \N3 except that the Si2456/33/14 drops the call
instead of connecting in wire mode.

Mark
Modem-to-DTE flow control
Disable all flow control—Note that this may only be used if the DTE speed and the VF speed are
guaranteed to match throughout the call.
Use CTS only
Use RTS/CTS
Use XON/XOFF flow control for modem-to-DTE interface. Does not enable modem-to-modem flow
control.
DTE speed
300 bps
