RealPort software
Digi devices use the patented RealPort COM/TTY port redirection for Microsoft
Windows. RealPort software provides a virtual connection to serial devices, no matter
where they reside on the network. The software is installed directly on the host PC and
allows applications to talk to devices across a network as though the devices were directly
attached to the host. Actually, the devices are connected to a Digi device somewhere on
the network.
RealPort is unique among COM port re-directors because it is the only implementation
that allows multiple connections to multiple ports over a single TCP/IP connection. Other
implementations require a separate TCP/IP connection for each serial port. Unique
features also include full hardware and software flow control, as well as tunable latency
and throughput.
Access to RealPort services can be enabled or disabled.
Encrypted RealPort
Digi devices also support RealPort software with encryption. Encrypted RealPort offers a
secure Ethernet connection between the COM or TTY port and a device server or terminal
server. Encryption prevents internal and external snooping of data across the network by
encapsulating the TCP/IP packets in a Secure Sockets Layer (SSL) connection and
encrypting the data using Advanced Encryption Standard (AES), one of the latest, most
efficient security algorithms. Access to Encrypted RealPort services can be enabled or
disabled.
Digi’s RealPort with encryption driver has earned Microsoft’s Windows Hardware
Quality Lab (WHQL) certification.
Drivers are available for a wide range of operating systems, including Microsoft Windows
Server 2003, Windows XP, Windows 2000, Windows NT, Windows 98, Windows ME;
SCO Open Server; Linux; AIX; Sun Solaris SPARC; Intel; and HP-UX. It is ideal for
financial, retail/point-of-sale, government or any application requiring enhanced security
to protect sensitive information.
