Using MFP menus
Robust XON Determines whether the MFP
communicates availability to the
computer.
This menu item only applies to the
serial port if Serial Protocol is set to
XON/XOFF.
Off* The MFP waits to receive data from
the computer.
On The MFP sends a continuous stream
of XONs to the host computer to
indicate that the serial port is ready to
receive more data.
Baud Specifies the rate at which data can
be received through the serial port.
Note: 138200, 172800, 230400,
and 345600 baud rates appear in
the Standard Serial menu. These
values do not appear in the Serial
Option 1, Serial Option 2, or Serial
Option 3 menus.

Honor DSR Determines whether the MFP uses
the Data Set Ready (DSR) signal.
DSR is one of the handshaking
signals for most serial interface
cables.
The serial interface uses DSR to
distinguish data sent by the
computer from data created by
electrical noise in the serial cable.
This electrical noise can cause stray
characters to print. Select On to
prevent stray characters from
printing.
Off* All data received by the serial port is
treated as valid data.
On Only data received while the DSR
signal is high is treated as valid.
