RealPort software
ConnectPort LTS products use the patented RealPort COM/TTY port redirection for Microsoft
Windows, UNIX, and Linux environments. 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
ConnectPort LTS products 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.
