V.42/MNP/Buffer Configuration Options Ð Singleport Mode A

EC Fallbck Char: 013 ASCI

Nxt " 013 ASCI

This configuration option only appears when 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.

Flw Cntl of DTE: CTS_to_DTE

Nxt CTS_to_DTE Disable XON/XOFF

This configuration option only appears when Async/Sync Mode is configured for Async, and Error Control Mode is not configured for DirectMode.

Flow Control of DTE. Determines how the modem controls the flow of data from the DTE.

CTS to DTE ± Method of flow control in which the modem raises and lowers its CTS interface lead to indicate when the DTE should start and stop sending data.

Disable ± The modem cannot control the flow of data from the DTE.

XON/XOFF ± Method of flow control in which the modem sends XON and XOFF characters to the DTE to start and stop the flow of data.

The AT commands for Disable are \Q0, \Q5, and \Q6.

The AT commands for XON/XOFF are \Q1 and\Q4.

The AT commands for CTS to DTE are \Q2 and \Q3.

Flw Cntl of Mdm: RTS_to_Mdm

Nxt RTS_to_Mdm Disable XON/XOFF

This configuration option only appears when Async/Sync Mode is configured for Async, and Error Control Mode is not configured for DirectMode.

Flow Control of Modem. Determines how the DTE controls the flow of data from the modem.

RTS to Modem ± Method of flow control in which the modem respectively starts and stops data transmission based upon the ON and OFF state of the DTE's RTS signal.

Disable ± The DTE cannot control the flow of data from the modem.

XON/XOFF ± Method of flow control in which the modem starts and stops data flow based upon XON and XOFF characters received from the DTE.

The AT commands for Disable are \Q0, \Q2, and \Q4.

The AT commands for XON/XOFF are \Q1 and\Q5.

The AT commands for RTS to Modem are \Q3 and \Q6.
