DTE Interface Configuration Options — Mux DISABLED
Asyn Parity Bit: None
Nxt None Even Odd Mark Space
This configuration option only appears when Async/Sync Mode is configured for Async.
Asynchronous Parity Bit. Determines the type of asynchronous parity bit. The parity of the DTE must match the parity of
the modem. Parity options include None, Even, Odd, Mark, or Space.
None – No parity bit is used.
Even – Parity bit is set so that total number of 1's in data bits plus parity bit is even.
Odd – Parity bit is set so that total number of 1's in data bits plus parity bit is odd.
Mark – Parity bit is always set to 1. Only valid if Async #Data Bits configuration option is set to 7.
Space – Parity bit is always set to 0. Only valid if Async #Data Bits configuration option is set to 7.
NOTE: If the DTE Dialer Type configuration option is set to AT or V.25bis Async, then the total character size must
equal 10 bits. Total character size consists of start, data, parity, and stop bits. V.25bis Async must use 7 data
bits with even parity and 1 stop bit. The total character size for Error Control mode, Direct mode, or Buffer mode
must be 11 bits or less.
The AT prefix determines parity of the async character.
Asyn #Stop Bits: 1
Nxt 1 2
This configuration option only appears when Async/Sync Mode is configured for Async.
Asynchronous Number of Stop Bits. Selects 1 or 2 bits to signal the end of an asynchronous character.
NOTE: If the DTE Dialer Type configuration option is set to AT or V.25bis Async, then the total character size must
equal 10 bits. Total character size consists of start, data, parity, and stop bits. V.25bis Async must use 7 data
bits with even parity and 1 stop bit. The total character size for Error Control mode, Direct mode, or Buffer mode
must be 11 bits or less.
The AT prefix determines the number of stop bits via autobauding.
