Strict RFC 1179 control file: Select to disable control file extensions the LPD
service implements for some flavors of UNIX and LPR. This enforces the basic Line
Printer Daemon protocol.
l
Enable BSD compatibility mode: Select to have the LPD service emulate a BSD
UNIX server. Although RFC 1179 is supposed to describe the BSD LPD/LPR
protocol, and the LPD input in PReS Workflow is RFC1179-compliant, there are
some incompatibilities between the RFC and the BSD implementation. This option
compensates for some of these incompatibilities. If you are not sure about the
source of your output, clear this option.

l
Time-out (sec): Set the time in seconds the process waits for the transfer of bytes in
the data file before ending the transfer of this file. The default value for the Time-out
property is 7200 seconds (2 hours). On a time-out, partially received data files are
not passed to the rest of the process; the LPD input resets and is ready to receive
further data files. Log messages include the time-out duration.
Serial Input plugin preferences
Serial input plugin preferences control certain functions of the PlanetPress Serial Capture
service, which in turn has a direct impact on all Serial input tasks performed by PReS
Workflow on a given computer.

l
Serial port: Select the port of the computer where the Serial input is connected to
(COM1 through COM8).
l
Baud rate: Select the baud rate of the Serial input. The baud rate is the number of
bits transferred per second. The transferred bits include the start bit, the data bits,
the parity bit (if defined), and the stop bits.
l
Data bits: Select the number of data bits defining the incoming data file on this
serial port. The data bits transferred through a serial port represent the data content.
This excludes the start, parity, and stop bits: these are bits defining the beginning
and end of each unit of transferred data, as well as error detection provided by the
parity bit. The majority of serial ports use between five and eight data bits. Binary
data is typically transmitted as eight bits. Text-based data is transmitted as seven
bits or eight bits. If the data is based on the ASCII character set, a minimum of seven
