On-Line EXPRESS
Command Description
AT\Q DTE Flow Control Options. Selects the flow control
method the modem provides to the DTE to prevent the
modem’s buffer from overflowing with data. A data
buffer holds the data until the modem is ready to
transmit it. When the data buffer is full, flow control
instructs the DTE to stop sending to the modem while
the modem continues to send characters.
AT\Q0 Disables flow control.
AT\Q1 XON/XOFF software flow control.
AT\Q2 Returns ERROR.
AT\Q3 RTS/CTS hardware flow control. (default)
AT\T Set Inactivity Timer. Allows the modem to disconnect if
no data activity has occurred for the selected period of
time.
AT\T0 Disable inactivity timer.
AT\V Protocol Result Code. Responds with W0 and W2 options
only.
AT\V0 Disable protocol result code (connect 9600). (default)
AT\V1 Enable protocol result code (connect 9600/LAPM).
AT\X Set XON/XOFF Passthrough Option. Valid only if XON/
XOFF flow control is enabled, such as \G1 or \Q1;
otherwise, XON/XOFF will not be detected by the
modem, so always passthrough.
AT\X0 Process XON/XOFF per \G and \Q option; if XON/XOFF
flow control is enabled, do not pass XON/XOFF to the
remote modem or local DTE.
