V.42/MNP/Buffer Configuration Options

Flw Cntl of DTE: CTS_to_DTE

Nxt CTS_to_DTE Disable XON/XOFF

This configuration option only appears if Async/Sync Mode is configured for Async.

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 factory default is CTS to DTE.

AT command equivalent is \Qn.

Flw Cntl of Mdm: Disable

Nxt Disable XON/XOFF RTS_to_Mdm

This configuration option only appears if Async/Sync Mode is configured for Async.

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

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.

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.

The factory default is Disable.

AT command equivalent is \Qn.

XON/XOFF Psthru: Disable

Nxt Disable Enable

This configuration option only appears if Async/Sync Mode is configured for Async and the Flow Control configuration option is configured for XON/XOFF.

XON/XOFF Passthrough. Considers an XON/XOFF character as data and passes it on to the remote modem. In this case, the DTE at one end of the communications link can send flow control characters to the other DTE. This is also known as DTE to DTE flow control.

Disable ± Flow control characters are processed but are not passed on to the remote modem.

Enable ± Flow control characters are processed and passed on to the remote modem.

The factory default is Disable.

AT command equivalent is \Xn.
