ps
Describes the escape sequence that needs to be sent to the terminal to switch to the
appropriate physical page. The physical pages are numbered in the order they are
specified in the description file.
clear
Specifies the escape sequence to clear the screen.
The second column has the character sequence that needs to be sent to the terminal by Multi_View.
Timing Specification
The timing specification is the interval in tenths of a second that the utility waits before checking for an escape
sequence. The timing specification is defined below:
Mnemonic
Description
time
Specifies the interval, in units of 0.1 seconds, Multi_View will wait while reading
characters before checking for escape sequences.
A sample file for the Wyse50 terminal is provided in the following example:

Line 1
Gives all the different names that the Wyse50 terminal is known.
Line 2
Specifies the virtual screen 0 settings. When the help screen is displayed, <Shift>+<F1> is
displayed for the virtual screen 0. The entry means that the terminal is going to send a string with
the first ASCII character being start of header (01 Hex), second character a hyphen (-), and the
last character a carriage return <CR> when <Shift>+<F1> is entered on the terminal and that
Multi_View is switched to the shell/process associated with virtual screen 0.
Line 3
Specifies the entry for virtual screen 1.
Lines 4-8
Describes the hot keys to switch between the current and previous virtual screens, create a new
virtual screen, display the help on the hot keys, quit Multi_View with a zero exit status and end
Multi_View with a non-zero status respectively.
Lines 9,10 Describes the physical pages on the terminal. The second string on each line gives the escape
sequence that needs to be sent out to the terminal to switch to the appropriate physical page.
Line 11
Clear string to clear the screen.
Line 12
Specifies at least a 0.1 second wait in reading data before going ahead and check for hot keys.
Each character in the escape sequence or hot key can be specified as an ASCII character if it is printable. If not
printable, then it should be specified in an octal format with leading 0's, if needed, and preceded by a \. For
example, an ASCII escape character can be specified as \033.
Do not switch the screen while outputting as it may break the escape sequence sent to the terminal. When there is
more than one virtual screen, all outputs from the inactive virtual screens will be blocked. The virtual screen the
user is currently working on is the only active screen.
The fullest potential of Multi_View is realized on a multiscreen terminal; however, Multi_View can be used on a
dumb terminal that has only a single page of memory. When there is only one page, the screen output is
