This is a function of the operating system, and not C.  Since it comes
up every so often, I'll post an answer to comp.unix.progammer.

BTW, no operating system that I know of accompishes supressing echo
by using control characters; it is usually a bit flag in a status word
for the port, or something along those lines.
