      I'd agree that this still seems like the wrong question :-) Is the
      debugger running on the same machine as vim? Why does it use
      telnet? Else, can you make it not do that, and [telnet to the remote
      machine and ] just use the debugger with vim, without vim knowing
      abut telnet, on the remote host?

      Most vim use of things like :compiler and :make are non-interactive.
      I think if you need to do this then you should use Expect, and/or
      Perl/Ruby/???'s expect-like library to turn the telnet interaction
      into something scripted and non-interactive. Getting the
      interaction right is about the trickiest part of using Expect-like
      programs.

      Maybe the debugger has an API so you can drive it programmatically?
      That could save you some of the pain of handling interaction for
      humans by machine. Maybe someone knows about this debugger already,
      and if you tell people what it is they can help better?
