Transmitted Keyboard Codes
Transmitted codes are codes generated by the wireless sta-
tion’s keys and sent to the host computer or software ap-
plication in use. The following pages describe the capability
of the wireless stations to emulate codes generated by the
VT220 terminal keyboard’s main keypad, editing keypad,
auxiliary keypad, and top-row function keys.
Codes are sent via line edit (block) mode or optimized char-
acter mode selected through the keyboard function labeled
MODE on the overlay.
Line Edit Mode
Line edit (block) mode is a synchronous condition where the
wireless station temporarily stores or “buffers” keys you
press. It sends the cumulative data to the host computer
when you press one of the following terminating keys:
[ENTER]
[F6] through [F20], [PF1] through [PF4]
[CTRL]+[A] through [CTRL]+[Z]
Forward tab
DEL (7F hexadecimal)
Backspace
The following also apply to line edit mode:
"
When you press [PF1], the following key will also be
transmitted directly to the host computer.
"
When scanning, the wireless station automatically en-
ters line edit mode for each individual scan. When it
completes scanning, it returns to the mode it was set
at before it started scanning.
