5.2 Command-Line Interface
A terminal emulation program is used to emulate a video terminal, so as to access Ver-
saSync's CLI (Command-Line Interface) remotely via a serial cable. This may be required if
no other means of remotely accessing VersaSync are available, for example if Ethernet
ports are used otherwise or have been disabled (e.g., for security reasons).
5.2.1 Setting up a Terminal Emulator
If no other means are available to access VersaSync, a terminal emulation program can be
used to carry out certain configuration changes by accessing VersaSync's CLI (command-
line interface) via a serial port connection. An application example for this scenario is to
enable a network port so that the VersaSync Web UI can be used. While it is also possible
to retrieve selected logs, a terminal emulator does not replace the VersaSync Web UI.
Spectracom does not distribute or support its own terminal emulator, and newer Microsoft
operating systems no longer include HyperTerminal. However, there are several third-
party open-source programs available, such as TeraTerm
®
or PuTTY
®
. The example
below illustrates the use of TeraTerm. The setup procedure is similar when using other ter-
minal emulation programs.
Procedure:
1.
Connect the personal computer to the USB interface.
2.
Configure your terminal emulation program, using the following settings:
Port: COM1
Bits per second: 115200
Data bits: 8
Parity: None
Stop bits: 1
Flow control: None
