Introduction
This chapter provides information on the Trueport utility.
Trueport
Trueport is a com port redirector utility for the Device Server. It can be run in two modes:
z Trueport 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 Network Access
Server.
You use Trueport when you want to connect extra terminals to a server using a Device Server rather
than a multi-port serial card. Trueport is especially useful when you want to improve security, for
example, to see which user is logged onto which terminal. 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.
