DTE Interface Configuration Options

Asyn Parity Bit: None

Nxt None Even Odd Mark Space

This configuration option only appears if 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.

HNone

No parity bit is used.

HEven

Parity bit is set so that total number of 1’s in data bits plus parity bit is even.

HOdd

Parity bit is set so that total number of 1’s in data bits plus parity bit is odd.

HMark

Parity bit is always set to 1. Only valid if Async #Data Bits configuration option is set to 7.

HSpace

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 if 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.
