The way this configuration option functions depends on how the modem is configured for flow control.

When the modem is configured for XON/XOFF flow control (see \Q

n, Flow Control of DTE), this configuration option

determines if flow control characters received from the local DTE will be passed on to the remote modem.

If configured for modem-to-modem flow control (see \G – Modem to Modem Flow Control), this configuration option
determines if flow control characters received from the line will be passed on to the DTE.
