V.42/MNP/Buffer Configuration Options
XON/XOFF Psthru: Disable
Nxt Disable Enable
This configuration option is only available if Async/Sync Mode is configured for Async, and Flow
Control of Modem 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.
H
Disable
Flow control characters are processed but are not passed on to the remote modem.
H Enable
Flow control characters are processed and passed on to the remote modem.
The AT command for Disable is \X0.
The AT command for Enable is \X1.
Mdm/Mdm FlowCtl: Disable
Nxt Disable Enable
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, LAPM_or_Bufr, or BufferMode.
Modem-to-Modem Flow Control. If a modem’s buffers begin to fill due to data it is receiving from the remote
modem, but is not passing on to the DTE, it can issue XON/XOFF flow control characters to the remote
modem. This only applies if Buffer (nonerror control) mode is selected. If Error Control mode is enabled,
flow control between the modems will happen automatically, regardless of the setting of this option.
H
Disable
Modem does not respond to XON and XOFF characters received over the VF line. Also, the modem
will not transmit an XOFF character to the remote end if its receive buffers are full.
H
Enable
Modem stops transmitting data to the remote modem if it receives an XOFF character over the VF
line. An XON character will enable data transmission. Also, the modem will transmit an XOFF
character to the remote end if its receive buffers are full. Select this setting if the DTE rate is less
than the VF line rate or if the DTE must frequently stop the flow of data to process it.
The AT Command for Disable is \G0.
The AT Command for Enable is \G1.
