value is 1 bit. Set this option to match the number of stop bits trans-
mitted by the host.
Hdwe Flow Ctl
The Hdwe Flow Ctl (Hardware Flow Control) option allows you to pick
the type of hardware flow control used by your host. The choices are
DSR POL (default value: Lo), DSR (default value: Off), DTR POL
(default value: Lo), DTR (default value: On), RTS (default value: Off),
and CTS (default value: Off).
If your host uses hardware flow control, set this option to match the
type used by the host.
PS Protocol
This option sets the binary communications protocol (BCP) for com-
municating over a serial, parallel, or optional network interface to a
PostScript printer. Binary communications protocol 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. When communicat-
ing 8-bit binary data in Binary or Binary Fixed mode, the printer uses
the quoting mechanism of the BCP to distinguish between the special
control characters and print job binary data.
To differentiate data from the special control characters, any data that
is the same as one of the following special control characters must be
quoted:
ASCII
Keyboard

Name

Hex Value

Function
^A SOH 0x01 Quote data character
^C ETX 0x03 Abort job and flush to end of file
^D EOT 0x04 End-of-file marker
^E ENQ 0x05 (Reserved for future use)
^Q DC1 0x11 XON in XON/XOFF flow control
^S DC3 0x13 XOFF in XON/XOFF flow control
