software and describes the scope of this User's Guide.

What Is TeemTalk for Unix ?

TeemTalk is the essential connectivity tool for X Window based UNIX environments,
enabling non-X based applications to be run in the X environment. TeemTalk provides
precise emulation of a wide range of industry standard text and graphics terminals
with impressive additional features formulated to increase productivity and reduce
network loading. These include file transfer, dynamic window sizing, hotspots, soft
buttons, keyboard mapping, mouse button definition, customising capabilities,
scripting language, and an optional Application Programming Interface (API).
The X Window System & TeemTalk
The X Window System is a network-based windowing system that provides a
common graphical interface for application programs. It defines how applications
create windows and the graphics displayed in them.
X is based on a client-server model in which the client is the application program and
the server controls the display and keeps track of user input. Communication
between client and server can be achieved via networks, serial interfaces or internal
operating system streams using standard X protocols. Since X is both window based
and network oriented there can be multiple applications on the network creating
individual windows on an individual display. The display is therefore providing a
service to each application and hence is known as the X display server.
The basic function of TeemTalk is to accept DEC, Tektronix, Retrographics, West-
ward, etc., command sequences from a host application (client) and convert them into
equivalent X functions which can then be passed on to the X display server. This
means that current investment in host application software can be retained in the X
Windows environment.
