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 printe r. T he opt ions
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 factor y def ault 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 Pola rity: 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 of f).
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 int erfac e. The defau lt is norm al.
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.
