stdin and NUL. How ?

How do I accept a NUL character through the stdin stream ?

I don't know if you can. Why do you need to? There's probably another way to do it.

I was hoping to have a program that would accept piped or console input, and then send it over an RF link. I would then be able to send binary files and upgrades over the RF link.

Hmm, I'm not too sure about that then. I think if possibly you get the input with getc () (I'm assuming you're using C / C++ here - please tell me if I'm wrong), then you might be able to it. I'm not really sure though, as the null character is the 'not-a-character' character.
Good luck, anyway!

'fraid not. getc() seems to filter out NUL.

OK, the only other thing I can think of is to use fread (), which'll read raw binary data, without trying to interpret it as a character. I'm not sure how easy it would be to use that data then though.
