Character Codes Returned by INT 16h
When a 101Ćstyle keyboard is used:
"
Return all standard 83/84 style keyboard character codes, as is.
"
Mask the duplicate keys to the same 2Ćbyte code as their 83/84 style
counterparts.
"
Kill any character codes not compatible with the 83/84 key keyboard.
The column labeled Scan Codes In Hex," in the table below, lists the codes
offered to INT 09h by the keyboard controller through Port 60h. This table
shows the character codes returned in AX through the INT 16h standard
functions 00h/01h. The same values are returned using extended functions
10h/11h.
