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 or DTE Dialer Type is

enabled.

Asynchronous Parity Bit. Determines 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.

The factory default is None.

NOTE: The total character size for Buffer mode must be 10 bits. The total character size for Direct mode must be 11 bits

or less, and Async #Data Bits must be 7 or 8.

There is no AT command equivalent; 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 or DTE Dialer Type is

enabled.

Asynchronous Number of Stop Bits. Selects 1 or 2 bits to signal the end of an asynchronous character.

The factory default is 1.

NOTE: The total character size for Buffer mode must be 10 bits. The total character size for Direct mode must be 11 bits

or less, and Async #Data Bits must be 7 or 8.

There is no AT command equivalent; AT prefix determines the number of stop bits via autobauding.
