ETX/ACK, and none. The factory default is
XON/XOFF.
Xmit Sw
Flow Ctl The software communication protocol used by the host
to control communication with the printer. The options
are none, XON/XOFF, ETX/ACK. The factory default
is none.
Data Bits The number of data bits (either 7 bits or 8 bits)
transmitted per character. The factory default is 8 data
bits.
Stop Bits The number of stop bits (either 1 bit or 2 bits)
transmitted per character. The factory default is 1 bit.
Hdwe Flow
Ctl All the hardware flow control settings must be the same
as those of the host. The options are DSR POL (Data
Set Ready Polarity: high or low; factory default low),
DSR (Data Set Ready: on or off; factory default off),
DTR POL (Data Terminal Ready Polarity: high or low;
factory default low), DTR (Data Terminal Ready: on
or off; factory default on), RTS (Request to Send: on
or off; factory default off), and CTS (Clear to Send: on
or off; the factory default is off).
PS Protocol This option sets the binary communications protocol
(BCP) for communicating over a serial, parallel, or
optional network interface to a PostScript printer. BCP
allows any 8-bit binary value (0-255) to be treated as
data while allowing a few of the values to function as
special control characters.
Four choices are available through the PS Protocol
submenu for the serial interface. The default is normal.
Normal: Enables standard, ASCII hex protocol. Data
is sent and received in ASCII format. Print jobs can
alter this value through PostScript operators.
Normal Fixed: Enables standard, ASCII hex protocol.
Print jobs cannot alter this value through PostScript
operators.
BinaryEnables binary communications protocol
(BCP). Print jobs can alter this value through
PostScript operators.
