hanging telnet, rlogin, clear_tty and 4.0.1

[Chris Johnston]

I have seen the same thing on a 386i OS4.0.  I had etherd running in the
background on ttyp1.  using stty seemed to have no effect.  killing the
etherd process cleared everything up.  (Only took me about a week to guess
it was always the same pseudo terminal.)

So... If the pty won't leave raw mode get used to typing control-J and
kill that background process.
