Hmm. This is wrong. Are you certain about the /etc/services entries
and the way you are starting the HylaFAX daemons? You might take a
look at my SunOS notes at
	http://cirl.harvard.edu/~raoul/INSTALL-sunos4.1.x-v4.0pl1.php

What are you telnetting with in this case? The sun server, or a Windows box,
or what?

My suspicion is that the telnet client you are using stinks and that
it a failure of the telnet, not the hfaxd, but that is merely a guess.
