Abstract

Described is a method where a user can choose a cursor movement mode, where the default function of the cursor movement keys is to move only to input-capable positions instead of one row or one column at a time, when running host-based applications.

User-Selectable Cursor Movement Mode to Input-Only Positions

      Described is a method where a user can choose a cursor movement
mode, where the default function of the cursor movement keys is to
move only to input-capable positions instead of one row or one column
at a time, when running host-based applications.

      Some host-based applications use screen-based I/O:  the user
fills in information on a display screen into one or more entry
fields and when completed, presses the Enter key or a Command key.
At this time, the application receives data from the entry fields on
the display screen.

      For some host-based applications, the typical function of the
cursor movement keys (4 arrow keys) is to simply move the cursor one
row or column at a time.  However, the user could choose between the
above cursor movement mode and a 'new' cursor movement mode where the
cursor moves to input-capable positions only.

      When the new cursor movement mode is set on by the user, a Work
Station Controller (WSC) can restrict the cursor to input-capable
positions on the display screen.  The WSC provides attachment of
multiple Non-Programmable Terminals (NPT).  There are at least three
alternatives to WSC support, where any one alternative can be
implemented or any combination of these alternatives can be
implemented.

      The first alternative would involve an additional parameter in
the host "user-profile".  The user can "adjust" their user profile to
fit their particular desires; for example, "cursor-movement-mode".  A
display data stream 'customization' command could be enhanced to
define two new bit flags: one bit turning on the new cursor movement
mode and one bit to turn off the new cursor movement mode.  If
neither
bit flag is set on, cursor movement mode remains unchanged.  The
'customization' command could be sent when the NPT is powered up
or varied on.

      The second alternative involves enhancements to newer NPTs.  A
new NPT set-up option could be added which defines the cursor
movement mode.  If the user has set cursor movement to input-capable
positions only, the NPT turns on a previously-reserved bit flag in
NPT information read by the...
