  'grep' says no.

  Look at $prefix/share/dejagnu/remote.exp, in particular "proc call_remote"
is quite informative for how you'd go about adding an extra remote protocol.
You might want to do a minor enhancement of telnet.exp, since what you're
doing sounds largely like the telnet protocol with a bit of extra gubbins to
launch 'cu' immediately after connecting over telnet.
