CSMIM-T1 Hardware Installation Guide 7-39
\X n XON/XOFF Pass-Through
\X0 Processes XON/XOFF flow control characters.
\X1 Processes XON/XOFF flow control characters and passes them to
the local or remote system so that the local or remote device also
processes them.
Determines whether XON/XOFF flow control characters pass to
the remote or local modem. With XON/XOFF flow control
enabled on the serial port (\Q1) and pass through enabled (\X1),
the modem also transmits to the remote device any XON and
XOFF characters sent to the serial port from the local device.
Y
n Long Space Disconnect
Y0 Disables long space disconnect on receipt of H, or DTR drop if
&D2 or &D3 is set.
Y1 Enables long space disconnect on receipt of H, or DTR drop if
&D2 or &D3 is set.
Sends a Break up to 4 seconds before disconnecting in response
to an H command, or if DTR drops and either &D2 or &D3 is set.
If &D3 is set and DTR drops, the modem disconnects. If the
answer modem sees the Break, it drops the connection.
NOTE The “W” dial modifier causes the modem to wait for dial tone
regardless of the X setting.
!
CAUTION
With \ X0 set and XON/XOFF flow control enabled, local
devices such as computers or printers may send XON and
XOFF characters to the modem serial port. If the modem is
already controlling data flow to the remote system, local flow
control characters will not interfere with the connection.
However, if \ X1 is set, local flow control characters also pass to
the remote system. These characters intended for the local
system may turn on the flow of data from the remote system
before the modem is ready to receive more data, resulting in a
loss of data.
