l Protocol options group
l Log all Winsock and network messages: Select to have PlanetPress Suite Workflow Tools keep a log of
all Winsock and other network messages that occur through the LPD service. These are messages related to
jobs being sent from other systems through LPR, and being received by PlanetPress Suite Workflow Tools via
LPD. Since these messages can accumulate, you have the option of not logging them. Log files are kept in the
Log folder, which is located in the PlanetPress Suite installation folder. They are named lpddate.log, where
date is the current date in the yyyymmdd numerical format. Note that changing this option also affects the log
displayed in the PlanetPress Suite Service Console.
l No source port range restriction: Select to remove any restrictions on the port of the LPR client computer
that PlanetPress Suite Workflow Tools accepts data files from. Clear to have PlanetPress Suite Workflow Tools
only accept data files sent from ports ranging between 721 and 731 on the LPR client computer.
l 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 PlanetPress Suite Workflow Tools
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 LDP settings group
l Timeout (sec): Set the time in seconds the PlanetPress Suite 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 Service User Options
Serial input user options control certain functions of the PlanetPress Suite Workflow Tools Serial Capture service, which in turn
has a direct impact on all Serial input tasks performed by PlanetPress Suite Workflow Tools on a given computer.
The available Serial input user options are as follows:
l Serial settings group
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 trans-
ferred 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 char-
acter set, a minimum of seven bits is required. If an eighth bit is used, it must have a value of 0. If the data is
based on the extended ASCII character set, eight bits must be used.
l Parity: Select the type of parity used for error detection. The parity transfers through the serial connection as a
single bit. It is used to verify that each set of data bits transfers correctly. It is then stripped away before the
data file passes through the rest of the PlanetPress Suite Workflow Tools process. Select None to ignore all par-
ity bits; no error detection occurs.
l Stop bits: Since most serial ports operate asynchronously, the transmitted byte must be identified by start and
stop bits. The start bit indicates when the data byte is about to begin and the stop bit(s) indicates when the data
byte was transferred. The start bit is always 0 to mark the beginning of the byte, but the stop bit can be a single
1, or two bits each with a value of 1.
