Introduction
1.1 About this
Guide
This guide describes the features and applications of the
Terminal Server from the level of novice user to more
experienced system installer. It includes information about
the table top units as well as the rack mount unit (form factor
is the only difference between them).
As an experienced user, you may save yourself some set-up time
by following the instructions in the Terminal Server Quick Start
Guide included with your package. Consult other sections in
this guide as required. Release notes are also available with this
unit (enclosed, or available from our web sites).
Note: The BLACK BOX
®
Terminal Server supports Windows
®
systems including Windows NT
®
, Windows
®
95/98 and
Windows
®
3.x. When compared to Unix, there are several key
features not included with Windows
®
systems such as TFTP,
dial-out socket connections, etc. However, we have provided
a briefing on these in the applicable sections. In many cases,
we will point you to our FTP sites for the latest tips and
software for the Terminal Server and Windows
®
systems.
This guide is sectioned as follows:

1.4 Terminal
Server
Features
The Terminal Server is a TCP/IP server with (depending on the
version) 2, 4, 8 or 16, RS-232 or RS-422 ports for making serial
network connections. It attaches to your TCP/IP network and
allows serial devices such as modems, terminals and printers to
access the network.

RS-232/RS422
Functionally, the difference between RS-232 and RS-422
versions is the absence of support for hardware flow control
lines (RTS and CTS) and modem control lines (DSR, DTR and
DCD) in the RS-422 version. The performance and support
for 115.2k baud are unaffected by the different serial ports.
RS-422 uses differential signalling and is capable of handling
longer distance due to superior noise immunity when
installed with suitable cabling.
Software
description
The Terminal Server comes with the Software Support Disk.
This disk contains the latest ‘released’ firmware and the
redirector software for Unix systems called
ioland . The
firmware is a backup copy and generally not used. The
ioland software is used for setting up printers and dial-out
modems on Unix.

10
Terminal Server - User and Administration Guide
The Terminal Server uses TFTP for downloading new
firmware.
tftpd is included with Unix systems such as SCO,
AIX and HP-UX but disabled by default.
Consult your Unix manual on this subject. On Windows
®
,
tftpd is not provided at this time (see our FTP site for a
shareware
tftpd program).
Note: Beta copies of the ‘next’ firmware release are usually
available on web sites (consult README files before
downloading).
Regarding
ioland , for printers/modems on Unix systems, the
source code
ioland.c is provided. There are also several
binaries of
ioland ready to run for various Unix systems (i.e.
SCO, AIX, HP-UX, Solaris, etc.). The source code can be
compiled on any Unix system (consult your Unix manual
on this subject).
Note: The most recent versions of these binaries should be
available on web sites.
