Command Description
\Q n SET SERIAL PORT FLOW CONTROL
This command specifies the DTE-to-modem flow control.
Software flow control uses the XOFF and XON characters to
stop and start data transmission, respectively, both to and
from the DTE.
One-way hardware flow control uses the CTS (Clear to
Send) signal to stop/start data from the DTE only, while
two-way hardware flow control also uses the RTS (Request
to Send) signal to start data from the modem.
For more information on flow control, also refer to the \G and
\X commands. Flow control is also described in Appendix E,
Advanced Modem Concepts , starting on page NO TAG.

\T n SET INACTIVITY TIMER
This command forces the modem to disconnect if no data is
transmitted or received within a specified time period. This
timer applies only if the modem is not in Direct mode (\N1).
\T0
\T1–90 Length in minutes.
\X n
XON/XOFF PASSTHROUGH FLOW CONTROL
This command controls whether or not the modem passes
XON/XOFF characters from the locally attached computer
through to the remote modem.
This command is ignored if the modem is connected in an
error control mode (see \N), as the error control protocol
provides its own flow control.
For more information on flow control, also refer to the \G and
\Q commands. Flow control is also described in Appendix E,
Advanced Modem Concepts , starting on page NO TAG.
