I meant something that is outside this function.

You mean, `cprintf' _buffers_ text and doesn't output it until you
send "\r\n"?

That would be weird: `cprintf' doesn't do any buffering at all, it
should output everything immediately.  Hmm.  The only case where the
screen might not be updated immediately is on Far-Eastern DOS
versions.  But that's not your case, right?

What happens if you use `cputc' to output each character, instead of
`cprintf'?
