Article 35177 of comp.sys.apple2: Subject: Re: Entended GS Keyboard Lights Sender: root@ucsbcsl.ucsb.edu The extended keyboard's lights are accessed through ADB commands. You use the ADB SendInfo call to send the commands to the keyboard. The parameters are: 2 byte parameter count 4 byte pointer to data to send to the keyboard 2 byte $00A2 - tells ADB Tools to send data to the keyboard The ADB data is in the form (in binary) 1111_1abc_1111_1111 Where a is the numlock light, b is the caps lock light, and c is the scroll lock light. Set the bit to turn on the light, clear it to turn it off. This information comes from the now-defunct 8/16 magazine, August 1990 issue. *-Eric Shepherd-----uerics@mcl.mcl.ucsb.edu-----------AOL: Sheppy--------------* * Programmers' Tip #1: When in doubt, rewrite from scratch! * *------------------------------------------------------------------------------*
