GIntroduction
This chapter provides information on the TruePort and Decoder utilities.
True Por t
TruePort is a com port redirector utility for the IOLAN. It can be run in two modes:
zTruePort 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.
zTrueP ort Lite mod e—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.
For more information, see the TruePort User Guide or the TruePort Installation and Configuration
Guide for Windows® NT on the CD-ROM.
