Setting up Dedicated hosts ensures that the units will always talk to each other. Enabling
Autostart for both units enables one Terminal Server to send data to the other Terminal
Server without having to wait for a serial carriage return to start the session. LES_B knows
exactly which other Terminal Server to accept connections from. Finally, when Autostart
is enabled, the access mode must be either Local or Dynamic (Dynamic is more flexible).

4.2.3 Multi-port Serial Tunnel Configuration

You can create serial tunnels for any available ports on the Terminal Server. Each serial
tunnel must point from one Terminal Server port to one different serial device port (such
as a serial port on a Terminal Server or MSS server).

4.3 Comm Port Redirector

The Black Box Comm Port Redirector application allows PCs to share modems and other
serial devices connected to the Terminal Server using Microsoft Windows or DOS
communication applications. The Redirector intercepts communications to specified
Comm ports and sends them over an IP network connection to the Terminal Server serial
port. This enables the PC to use the Terminal Server serial port as if it were one of the PC
Comm ports. Using their existing communications software, PC users dial out to a remote
host through a modem connected to the Terminal Server.
The Comm Port Redirector software and installation instructions are included on the
distribution CD-ROM and web site.

4.4 Enhanced Serial Support

Enhanced serial handling support has been added to the Terminal Server product line.
These new features allow much more control of how a server will bundle received serial
characters into network packets. Several new commands have been added to configure this
functionality.
To start a connection, the autostart functionality has been enhanced to allow sessions to be
initiated by a sequence of 1 or 2 characters. Either of the characters can be a wildcard,
signified by the ANY keyword.
DEF PORT n AUTOSTART CHAR ["x" | ANY | NONE] ["x" | ANY]
In addition, the characters that start the connection can either be passed to the host as the
first bytes of data or can be discarded.
DEF PORT n AUTOSTART SAVE [1 | 2 | NONE]
