Hi. I want a sinus tone from my computers loudspeakers, for comparative use. in old IBM 77 basic, you can do that, like play (Hz),(duration ms) But how is it done in Metacard?? I really doesn't understand? (I use the loudspeaker output to an condensatore and a ac/dc converter to guide micro relays, an idiot proof way that works on all computers with a loudspeaker output, but i want to modernise the look and feel of my "Idiot" I/O system) Oscar (metacard is a nice working bastard (Would you knew what i mean)) ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com Archives: http://www.mail-archive.com/metacard%40lists.best.com/ Info: http://www.xworlds.com/metacard/mailinglist.htm Please send bug reports to <[EMAIL PROTECTED]>, not this list.
