3-2 About RealPort
About RealPort
This section provides a brief introduction to RealPort.
What is RealPort?
RealPort is a feature that allows network-based host systems to use the ports of the Dig
One/PortServer TS 2/4 as though they were the host system’s own ports, appearing and behaving as
local ports to the network-based host.
RealPort Advantages
RealPort provides the following advantages:
• It expands the number of ports available to the host system.
• It enables Dig One/PortServer TS 2/4 ports to be treated as if they were directly connected to the
host, which means they use all standard operating system interfaces that control baud rate, parity,
stop bits, and flow control.
• It enables host administrators to do most of the required configuration on the host, the system
with which the administrator is most familiar.
• It dramatically reduces host CPU overhead because multiple terminal or printer sessions are
multiplexed over the same TCP/IP connection.
Configuring the RealPort Software
You must install and configure RealPort software on each host that will use RealPort ports. See the
RealPort documentation for more information.
Configuration Options
You can configure Dig One/PortServer TS 2/4 for RealPort from the command line or using the web
interface. For information on using the web interface, see "Configuring Ports: Web Interface" on
page 3-3.
