The newest MacIP Telnet (MPW version) that Bill Croft just placed into
the info-mac archives is substantially more robust than the previous
copy.  The previous copy had a major bug in the code that dealt with
the new KIP software and it was just plain old luck that it ever
worked.

Outstanding bugs/features that I can remember are:

o You cannot switch working directories using "Commands" Sendfile
  command.  Attempting to do so will cause telnet to bomb.  Anyone who
  can figure out how to fix this or even just what the problem is,
  please let everyone know!

o The terminal emulation code isn't as robust as it should be.  For
  example, updates don't quite happen correctly when the telnet window
  is the active window, but not the front window.  Some of the screen
  commands don't do range checking either...  Also, no provisions for
  remapping the "backspace" (on the plus)/"delete" (on the SE) to
  backspace vs. rubout (this always ends up driving me up the wall).
  Anyone who wants to fix these things...

o Some problems may occur with using desk accessories...  I think this
  is due to stack space problems, but am not sure.
 
o The new TFtp menu is nonstandard and more than a little silly, but
  it does work.  If anyone has a clean way to handle the menu, go
  ahead...  (dialog box maybe?)  The intent is to provide the server
  functionality that the old tftp program did; however, all the user
  tftp support is still missing.

o The "Send" "IP Address" has been reenabled; I suppose it was dropped
  to allow telnet to run on a 128K Mac in the past.  It is
  particularly useful with the dynamic IP address assignment.

o Won't run with TFTP in less than O(200KB).  Should run on 512.  I
  would be surprised if it didn't run on a 512E.  However, hasn't been
  tested on anything except a Plus or SE.  May not run at all on a
  128K Mac.

o You cannot switch "working directories" for file transfers - it is
  the directory that telnet was launched from; however, you should be
  able to specify the fully qualified name as "vol:directory:file" (it
  is MPW style where the prefix "::" means one up and the prefix ":"
  means current directory).

o This version of telnet still uses the old IEN116 name service, not
  the domain name service; however, I think it actually works
  correctly now (there was an alignment problem before).

o The copy that went out has the maximum number of TFTP connections
  allowed set to two (e.g. you can be doing two tftp xfers at a time).
  No particular reason except that we were playing with it to see if
  that code worked or not.  Shouldn't cause any problems.

o Aborted file transfers (downloads) sometimes result in files
  remaining open and thus locked.

Basically, while quite a few bugs remain, you should find it as
useable and more robust than the "Lisa Pascal" version available
before the advent of KIP1086.
