Re: [PLUG] speaker beep question

[epike@isinet.com]

Ok thanks.  

But seeing this will have to be some more 
work & reasearch on my part I will just stick with
normal beeps for now (1 beep ok, 2 beeps error, etc).

BTW, no /dev/speaker on linux, It appears sound creation
on speaker emulates sound cards.  Either that or 
I'd have to go to outputting values to certain PC ports,
both of which I do not wish to go into...its just for
scripting on a headless linux box and need not go that 
sophisticated.

so anyway thanks for all the inputs, 

for now i'd just continue beeping normally 
(until later until I can afford an lcd panel :-)
