Introduction
This chapter provides information on the TruePort and Decoder utilities.
TruePort
TruePort is a com port redirector utility for the IOLAN. It can be run in two modes:
z TruePort Full mode—This mode allows complete device control and operates exactly like a
directly connected serial port. It provides a complete COM port interface between the attached
serial device and the network.
z TruePort Lite mode—This mode provides a simple raw data interface between the device and
the network. Although the port will still operate as a COM port, control signals are ignored. In
this mode, the serial communications parameters must be configured on the IOLAN.
You use TruePort when you want to connect extra terminals to a server using the IOLAN rather than
a multi-port serial card. TruePort is especially useful when you want to improve data security, as you
can enable an SSL/TLS connection between the TruePort host port and the IOLAN. When run on
UNIX, TruePort allows you to print directly from a terminal to an attached printer (transparent
printing). You can also remap the slow baud rate of your UNIX server to a faster baud rate, as shown
below.

Currently, TruePort is supported on Linux, Windows, SCO, Solaris, and others. For a complete list of
of supported operating systems, see the Perle website.

Guide for Windows NT on the CD-ROM.
