3.8 Multi_View Utility Installation
This section guides you through the Multi_View Utility for SCO and
UNIXWare systems. During the installation of the ISI4608 drivers,
you will also install the Multi_View utility for multiple-page terminals.
This section profiles the Multi_View utility and gives you the
necessary information to create a Multi_View information file.
Once installed, Multi_View can be invoked by typing the following
command:
Multi_View [ options]
The Multi_View initializes the multiple-page capability of terminals
with multiple pages of memory. While Multi_View works even on a
dumb terminal (without multiple pages of memory), your terminal(s)
should have multiple pages of memory and be capable of retaining
the position of the cursor on each page to get the proper effect.
Most state-of-the-art terminals have multiple pages of memory,
which allow them to switch between sessions. Each page of
memory available on the terminal allows its user to establish another
session on the host. The multiscreen capability of the terminal
stores the screen information and the cursor position for each
session to a different page of memory.
Multi_View allows the host to process the session-switching hot keys
and issue the necessary escape sequence to the terminal so that the
appropriate page is displayed on screen. Multi_View treats each
new screen opened by the user as a virtual screen and maintains
mapping between each virtual screen created and a page of memory
on the terminal. The number of virtual screens and pages of memory
available are dependent on the terminal emulation, the particular
terminal being used, and the number of pseudo devices created by
the system administrator during installation.
In an ideal case, there can be as many virtual screens as there are
pages of memory on the terminal. If there are more virtual screens
specified than there are pages of memory, then two virtual screens
may be mapped to a single page of memory, in which case, both
sessions’ screens are displayed when that page of memory is
recalled.
