Actually, I've tried the following (all accounts running tcsh as the
shell) telnets:
	netbsd 1.0b -> solaris 2.3:	ok
	solaris 2.3 -> netbsd 1.0b:	ok
	netbsd 1.0b -> sunos 4.1.3:	ok
	sunos 4.1.3 -> netbsd 1.0b:	not ok.

The telnet on solaris 2.3 (like a lot of the network stuff), although
not being precisely BSD4.3 networking bugforbug compatible, seems to
be smart enough to autodetect when it does or doesn't need the

So, yes, older 4.2 and probably 4.3 telnets do stuff up, but the newer
telnets (>= net/2? and solaris 2.x) seem to work ok.
