APPLICATION EXAMPLE
FEATURES/BENEFITS:
ALLOWS MULTIPLE CONNECTIONS TO MULTIPLE COM PORTS OVER A
SINGLE TCP/IP CONNECTION
Significantly reduces overhead compared to other COM port redirectors
MORE DEVICES PER SERVER THAN ANY OTHER COM PORT REDIRECTOR
Provides up to 4096 COM ports with Microsoft Windows and up to 65,000 TTY
devices with UNIX (limited only by OS and server processing power)
COMPREHENSIVE OS SUPPORT
Compatible with virtually any program
HARDWARE AND SOFTWARE FLOW CONTROL
Prevents data loss
TUNABLE LATENCY AND THROUGHPUT
Ensures optimum application performance
CONNECTION RECOVERY
– Provides fault tolerance for network failures
Digi’s patented RealPort software allows companies to easily network-enable serial devices
without spending valuable time and money to re-write existing application programs
Many of today’s key business applications were written to talk to
serial devices that are directly connected to servers. To better serve
their customers, businesses have found it necessary to locate serial
devices in places that are not always close to servers or PCs.
Digi’s RealPort software leverages the now-ubiquitous TCP/IP
network infrastructure to provide a virtual connection to serial
devices. The software is installed directly on the server and allows
applications to talk to devices across a network as though the
devices were directly attached to the server. In actuality, the
devices are connected to a Digi device server or terminal server
somewhere on the network.
RealPort software is unique among COM port redirectors. It is the
only implementation that allows multiple connections to multiple
ports over a single TCP/IP connection. This means RealPort
supports the maximum number of remote devices — the number
is restricted only by the operating system and server processing
power. Other implementations on the market require a separate
TCP/IP connection for each serial port, resulting in higher network
overhead and more processing demands on the server
(see diagram).
Other unique features include full hardware and software flow
control, as well as tunable latency and throughput. With these,
RealPort ensures optimum performance since data transfer is
adjusted according to specific application requirements. It also
provides connection recovery — after a network interruption
RealPort automatically reconnects the device to the COM port
without the application knowing there was a failure. Finally,
RealPort offers comprehensive operating system support including
AIX, HP-UX, Solaris, Linux, Windows 2000, XP, 7, 8, 8.1, 10 and
Windows Server 2003, 2008, 2012.
RealPort comes standard with all of Digi’s device servers and
terminal servers.

REALPORT SOLUTION
Other COM port redirectors
require a TCP/IP connection
for each serial port:
- Four times the overhead
- Four times the processing
