XON/XOFF
XON/XOFF/DTR
XON/XOFF/DTRDSR
Selects the hardware and software handshaking settings for the serial port
Notes:
DTR is the factory default setting.
DTR/DSR is a hardware handshaking setting.
XON/XOFF is a software handshaking setting.
XON/XOFF/DTR and XON/XOFF/DTR/DSR are combined hardware and
software handshaking settings.
Robust XON
On
Off
Determines whether or not the printer communicates availability to the computer
Notes:
Off is the factory default setting.
This menu item applies only to the serial port if Serial Protocol is set to
XON/XOFF.

Notes:
9600 is the factory default setting.
138200, 172800, 230400, and 345600 baud rates are displayed only in the
Standard Serial menu. These settings do not appear in the Serial Option or Serial
Option 2 menus.
Data Bits

Specifies the number of data bits that are sent in each transmission frame
Note:
8 is the factory default setting.
Parity
Even
Odd
None
Ignore
Sets the parity for serial input and output data frames
Note:
None is the factory default setting.
Honor DSR
On
Off
Determines whether the printer uses the DSR Signal. DSR is a handshaking signal
used by most serial cables.
Notes:
Off is the factory default setting.
The serial port uses DSR to distinguish data sent by the computer from data
created by electrical noise in the serial cable. The electrical noise can cause stray
characters to print. Select
On
to prevent stray characters from printing.
This menu item appears only if Serial RS-232/RS-422 is set to RS 232.
