Port Profiles
Each port profile determines the settings needed. Following are overviews
of the port profiles and screen shots showing their settings. For more
details about the port profile settings, click the Help link.
RealPort Port Profile
Installed on a network-based PC, RealPort emulates a serial port. That is,
the application “thinks” it is working with a real serial port, such as COM1.
When the application sends data to this serial port, RealPort encapsulates
the data and ships it across the network to the Digi device which in turn
routes it to the serial device. This is also referred to as COM Port
Redirection. The network is transparent to both the application and the
device.
With RealPort, SSL encryption is supported in network port 1027. Standard
RealPort service is on network port 771. Both can be configured on the
Advanced Network Settings page. To use SSL encryption, you must have a
RealPort driver that supports SSL. For Unix and Linux, you can use one of
these drivers: Linux, Solaris, AIX, SCO Openserver 5.x and 6, and HP-UX.
With Windows, you can use the Win2k/Xp/2003 driver online, which
supports Encrypted RealPort (OpenSSL/TLS1.0 128-bit AES).
A simple challenge/response MD5 hash authentication is also supported
by the Windows driver on fs1.
