RealPort parameters
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.
