DESCRIPTION
The Outbound Connection Daemon is part of the Data Communications and
Terminal Controller (DTC) Device File Access (DDFA) software. It man‐
ages the connection and data transfer to the remote terminal server
port. It can be spawned from the Dedicated Port Parser or run directly
from the shell.
For performance reasons, does not have a debug mode. However, a ver‐
sion called with debug facilities is available.
See ddfa(7) for more information on how to configure the DDFA software
and for an explanation of how it works.

Options
recognizes the following options:
The board number of a DTC.
If it is omitted, the port number option must
contain the full TCP service port address.
The and options must not be used if the IP
address given in the option is the IP address
of a port.
If the option explicitly names a terminal
server port, the option is not needed.
Specify the name (including the absolute path)
of the configuration file used to profile the
terminal server port. If this option is omit‐
ted, the default values specified in the
default file are used. If the file specified
does not exist, an error message is logged and
the following values are used (note that the
values for and are different from the default
values):
The absolute or relative path to the device file
that is linked by the software to the reserved
Applications use pseudonym and not the dynami‐
cally allocated slave.
Specify the logging level.
It determines the severity of messages sent to
The logging levels (and how they relate to
system logging levels) are as follows:
Log only LOG_CRIT messages.
Log only LOG_CRIT and LOG_ERR messages.
Log only LOG_CRIT, LOG_ERR, and LOG_WARN‐
ING messages.
Log all messages.
If this option is omitted, the logging level
is set to 1.
The IP address of the terminal server or the port.
A DTC port number or, if the
option is omitted, the TCP port service
address that will be used by the software to
access the port. If the value is omitted, the
value (Telnet) is used by default.

WARNINGS
In order to ensure that commands (such as display the correct device
file name (that is, the pseudonym), all pseudonyms should be placed
into the directory If pseudonyms are not specified for placement in
this directory, the correct display of device file names with many com‐
mands is not guaranteed.
In addition, in order to ensure that commands (such as and work cor‐
rectly, each pseudonym must be unique in its first 17 characters
(including the directory prefix If pseudonyms are not unique in their
first 17 characters, the correct functioning of many commands is not
guaranteed.
Also, in order to reliably handle timing mark negotiations (and ensure
that files printing on a printer attached to a terminal server have
been completely flushed to that printer), the following line must be
added near the end of each printer interface script for printers
attached to a terminal server:
The printer interface scripts reside in the directory The line must be
added just prior to the final command in each printer interface script.
If this line is not added as specified, the printing reliability of
printers attached to a terminal server is not guaranteed.
