Chapter 3—Software/Driver Installation
Multi_Setup Utility
This section guides you through the Multi_View Utility for SCO and UNIXWare systems.
While installing the ISIHI-2S/2U drivers, you 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 opened by typing the following command:
Multi_View [options]
Multi_View initializes the multiple page capacity of terminals with multiple pages of
memory. While Multi_View works even on a dumb terminal (without multiple pages of
memory), your terminal 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 that 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
screen information and 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 the appropriate page displays. 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 more virtual screens are specified than there are pages of memory, two virtual
screens can be mapped to a single page of memory where both sessionss screens display
when that page of memory is recalled.
Once Multi_View successfully reads the terminal description and initializes the terminal,
the hot key sequence for help displays. The following hot keys are defined:
Go to n
th
virtual screen
Create new virtual screen
Switch between current and previous screens
Provide help on hot keys
Quit Multi_View with an exit status of zero
End Multi_View with a nonzero exit status
