{ STEVEN TALLENT > I am look For a piece of code [...] that will turn off the speaker. This is tested code, and should do the trick. It does its work by turning off the PC speaker 18.2 times per second. This should reduce any Sound to maybe a click or two. Unfortunately, some games and music software will bypass it (ModPlay, Wolfenstein), but most beeps and whistles will be gone. This is a TSR Program, and takes about 3k memory (yuk), but you can load it high if you want. I've found it especially useful during late-night BBSing (no alarms at connect/File xfer finish). Hope this does the trick! Considering its size and relative isolation from normal Programs, I didn't see fit to use CLI/STI. } {$M 1024,0,0} {BTW, is there any way to make this smaller?!?} {$N-,S-,G+} { Use g- For 8088 systems, g+ For V20 and above } Program NoSpeak; Uses Dos; Procedure ShutOff; INTERRUPT; begin Port [97] := Port[97] and 253; {Turn off speaker and disconnect timer} end; begin SetIntVec( $1C, @ShutOff); Keep(0); end.
