Is there a simple way to do tcp i/o in Sun Lucid? 

Ideally, I'd like something like this:

 (with-open-tcp-stream (stream :address address :port port :direction :io)
   (write-string "..." stream)
   .
   .
   .
   (force-output stream)
   (read-line stream))

where address is an internet style address ("128.10.15.20" or
whatever) of the machine I want to contact, and port is the port
number on that machine which handles the service I want.

Does Sun Lucid provide a nice macro like WITH-TCP-STREAM, or even a
simple OPEN-TCP-STREAM function? Perhaps they've generalized OPEN so
that the "file" argument can be a tcp address+port specification?  Or
am I stuck doing lower level Unix socket i/o?
