Sorry if this is in the wrong place. I am developing a game for DOS in ASM (Believe it or not 😎 ) and I noticed that printing the bell character using either...

1mov ah,2
2mov dl,7	;ASCII bell Char
3int 21h		;Print It!

...or....

1mov ah,09h
2mov al,7	;ASCII bell Char
3mov bh,0	;Page 0
4mov bl,0	;Attribute
5mov cx,1	;Do it once
6int 10h		;Print it!

...does not generate a beep although all other sounds work. I talked to wjp and after looking at the sources (int10_char.cpp) he found that it had not implemented yet...

1switch (chr) {
2case 7:
3//TODO BEEP
4break;

Is there a way to work around this or would I have to rebuild the sources? Could you add this to 0.73?

Thanks to the developers for keeping DOS gaming alive! 😁

My build has it implemented at least in one place. You can download the patch from my homepage (Megabuild 4 -> some patch files -> beep.diff)

1+1=10
