Mandatory arguments

There are three mandatory arguments the daemon requires to mediate between the client
and server port:

Argument

Description

Server

The host name of Terminal Server that has the attached printer or
terminal.

Port

The TCP port on which the Terminal Server port is listening for
connection requests.

Link

A mnemonic filename in /dev which shall be linked to the slave
pseudo-tty selected by the daemon. This should be used as the
interface device for client processes since the pseudo-tty may
change during the daemon lifetime.
