I had to send the character \0 to my printer.
I tried :

fp = fopen ("PAR:", "w")

fprintf (fp, "aaa\000bbbb")
fprintf (fp, "aaa%cbbbb", 0x00)

The first sent until (not including) the \0, and the second just ignord it.

I also tried:

FileHandle *fh, *Open ()
unsinged char c;

c = 0;
fh = Open ("PAR:", O_WRONLY) (worked fine)
Write (fh, &c, 1L) (write failed)

and

int     fd, open ()

fd = open ("PAR:", O_WRONLY) (worked fine)
write (fd, &c, 1L) (the program was stuck)

What did I do wrong, and what is the right way to send 0x00 to the printer?

(I use Aztec 3.6a, and a A1000 with 1.5 MB of memory)

Thanks,
