Yes, Thank You. It turns out that suppress go ahead is what I really wanted. It took me some time to figure this out, but I needed to translate the dec values to oct and send them that way.

The code I am using now looks like this:

# send IAC WILL SUPPRESS-GOAHEAD
put( "\377\373\3\n" );
# send IAC DO SUPPRESS-GO-AHEAD
put( "\377\375\3\n" );

(where put() sends a scalar argument to the user)

Thanks all for your responses.
