*But*, as Gordon pointed out, those *aren't* telnet servers, and you'd
probably do better to use 'nc' than 'telnet'. While 'nc' isn't exactly
feature-filled, you're not able to *use* any telnet features with things
that aren't telnet servers anyway, so you really aren't losing anything.

(Admittedly, I've done the same thing... it's habit, and habits die
hard. This is one worth breaking, though; 'nc' should exit with a ^D,
which Konsole won't eat. Or had better not, because that would be a
serious bug if it did.)
