VTS
VTS (Virtual Terminal Server) is the third (right-most) tab of the Router page. To navigate to this tab, select Router from
the main menu and click VTS. From this tab you can configure the Virtual Terminal Server parameters.
The Virtual Terminal Server (VTS) is an application running inside the Viper that creates two socket endpoints. One
socket endpoint is called “left” and the other is called “right.” Any data received from the left socket endpoint is sent
over the right socket endpoint. Any data received from the right socket endpoint is sent over the left socket endpoint.
The socket endpoints can operate in TCP server mode, TCP client mode, or UDP mode.
Up to five (5) Virtual Terminal Servers can be configured and enabled. Each Virtual Terminal Server that is enabled
works independently of any others.
