NUL with cat

[james collins]

Hello,
This maybe a little off topic so feel free to respond privately. I am  
trying to test a doubletalk speech synthesizer using the cat command.  
 From the discussions forum from the apple website I was told that,
$ echo $'\00' | cat
would append a NUL character to the cat command? I wanted cat to  
append a NUL character at the end of a listing? I found out that my  
synthesizer needs a NUL character to speak. Like when I ran cat with  
nothing after it if I typed text, I wouldn't get any audio output. But  
if I ended the text with NUL my synthesizer would speak the text. So I  
am trying to append a NUL character to the cat command? But I can't  
seem to get the line from the apple website working? Any help would be  
appreciated.
