Setting Up Lines

Line and port is often used interchangeably. They are almost the same, that is, each line has an
associated port number (Line 1 is port 10001 by default).
How you set up a line is really determined by the device that is connected to the line. This
section goes over some of the common ways a line is used and things that you will want to keep
in mind when configuring the line.

Direct/Silent/Reverse Connections

Direct connections bypass the Terminal Server, enabling the user to log straight into a specific
host. A direct connection is recommended where a user logging in to the Terminal Server is not
required. It is also recommended where multiple sessions are not a requirement. Direct
connections require user interaction: the message
the user's screen and the session to the host is not initiated until
host login prompt is displayed. The message is redisplayed on logout.
Silent connections are the same as direct connections except that they are permanently
established. The host login prompt is displayed on the screen. Logging out redisplays this
prompt. Silent connections, unlike direct connections, however, make permanent use of pseudo
tty resources and therefore consume host resources even when not in use.
Reverse connections enable a host on the network to establish a connection through the
Terminal Server port to a serial device.

Virtual Modems

behaves like two modems connected across a telephone line. Typically, you use the
