V.42/MNP/Buffer Configuration Options

EC Negotiat Bfr: Disable

Nxt Disable Enable Disab&Switch

This configuration option is only available if Async/Sync Mode is configured for Async, and Error Control Mode is configured for V42/MNPorBfr, MNP_or_Buffr, or LAPM_or_Bufr.

Error Control Negotiate Buffer. Determines if the answering modem buffers the data that it received from the remote modem during an interval in which the modem attempts to establish a connection using error control. Online changes do not take effect until a disconnect occurs.

HDisable

Data is not buffered during the link negotiating (handshaking) sequence.

HEnable

Data is buffered while the link is being established. Initialization data is not passed on the DTE during the handshaking sequence.

HDisable and Switch

Data is not buffered during the handshaking sequence. However, when the modem receives an error control fallback character, it switches to Buffer mode. (Refer to the EC Fallback Char configuration option.)

The AT command for Disable is \C0.

The AT command for Enable is \C1.

The AT command for Disab&Switch is \C2.

EC Fallbck Char: 013 ASCI

Nxt " 013 ASCI

This configuration option is only available if Async/Sync Mode is configured for Async, and EC Negotiate Buffer is not configured for Disable.

Error Control Fallback Character. This configuration option allows you to enter the ASCII value of the error control fallback character. This provides the remote modem with the ability to end the error control link negotiating (handshaking) sequence by sending this character. The modems will connect in Buffer mode (no error control). Online changes do not take effect until a disconnect occurs. When the modem receives this fallback character it switches to Buffer mode and transmits an EC fallback character to the DTE. When comparing incoming characters for a match against the EC fallback character, the modem ignores parity.

The AT command is %An, where n is a value from 0 to 127.
