RealPort Software

For more details, see "Assign an IP Address to the Device" on page 69.
Digi Connect devices use the patented RealPort COM/TTY port redirection for Microsoft
Windows, UNIX, and Linux environments (not supported in Digi Connect WAN).
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 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 server or terminal
server 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 Connect devices support the patent-pending RealPort software with encryption. The
Digi Connect WAN does not support Encrypted RealPort. 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
Protocol (DHCP) is an Internet protocol for automating the configuration of
computers that use TCP/IP. DHCP can be used to automatically assign IP
addresses, to deliver TCP/IP stack configuration parameters such as the subnet
mask and default router, and to provide other configuration information.
Auto Private IP Addressing (APIPA), also known as Auto-IP: A standard
protocol that will automatically assign an IP address from a reserved pool of
standard Auto-IP addresses to the computer on which it is installed. The device
is set to obtain its IP address automatically from a DHCP server. But if the
DHCP server is unavailable or nonexistent, Auto-IP will assign the device an
IP. If DHCP is enabled or responds later or you use ADDP, both will override
the Auto-IP address previously assigned.
