Key Codes
This appendix lists the key codes for the terminal's ASCII and
ANSI personalities.
Tables B-1 through B-3 list ASCII codes for each of the three
keyboards available for the terminal. Codes are given for editing
and special keys only. Alphanumeric keys send the standard
ASCII codes (see Wyse Works ASCII Table).
Table B-4 summarizes the hexadeeimal values of the scan codes
sent by the keys on all keyboards when the terminal is in the PC
Term personality: each key sends one scan code when pressed
(the
down
code) and another code when released (the
up
code)
The table gives the codes for the editing and special keys only.
Scan codes for the alphanumeric and function keys are shown
on the VT220- and Enhanced PC-style keyboard illustrations.
Only the down codes are shown-the high bit is set when the
key is released. (The same codes are sent by the alphanumeric
and function keys on the other keyboards when the terminal is
in the PC Term personality.)
Table B-5 lists function key default codes for all keyboards and
all ASCII personalities except PC Term.
