BTW, one of the cool things that CMUCL offers is the option to execute
the process under a PTY, see

  <http://common-lisp.net/project/cmucl/doc/cmu-user/extensions.html#toc46>.

This could, e.g., be used to implement something like Expect. Do other
Lisps offer similar functionality? I specifically asked on the
LispWorks mailing list and got no reply from which I guess it can't be
done with LW. What about SBCL, AllegroCL, CLISP, and so on?

Cheers,
Edi.

In SBCL, the RUN-PROGRAM fucntion is pretty much the same as the CMUCL
one.  So, for example

* (sb-ext:run-program "/usr/bin/tty" () :pty t)

#<SB-IMPL::PROCESS 8071 :EXITED>
* (read-line (process-pty *))

"/dev/ttyp2
NIL
