Wish list for the telnet program:

- Remove hard-wired host address table in favour of a network-based IP name
  server or a name->address cache in the internetserver.

- Remove the termtype.c function if the terminal agents ever provide a
  get-terminal-type service or if a TERM enviroment variable is defined.

- Extend host name syntax to allow specification of a source route. e.g.

	relay,relay,...,dest.port  -- for loose source route
	relay;relay;...;dest.port  -- for strict source route

  where "dest" is either a name or an address, with optional .port,
  and "relay" is either a name or an address (no port specification).
  This should be done concurrently with adding source routing support
  to the internetserver.

- Twiddle with the pad mode bits in such a way as to allow the user to
  make use of the Toggle PagedOutput menu item while connected to a
  remote host.

- Make the helper process be the "break process" and also the process
  that establishes the TCP connection.  Then, a ^c could terminate the
  connection attempt and return to the host prompt.

- Keep the local terminal in line-edit mode whenever the remote host
  is not echoing.  This would require some work on the terminal agents
  to support the entering of any 8-bit character and a way to submit
  all buffered input without an appended CR or anything else.

- send RESET escape sequence to terminal (VGTS) on connection establishment/
  clearing?  Really want a terminal-independent reset request.

- don't send TERMINAL-TYPE IS except in response to TERMINAL-TYPE SEND.
  (Do this when our Unix telnet servers are fixed.)

- why does ^Z sometimes take a *long* time to terminate the program?
