Running Scilab in an emacs buffer - hangs

I have set up the above scilab.el as per instructions, but when the comint
buffer opens from (scilab-shell), instead of Scilab printing:
        ___________________________________________
                         scilab-3.0

        ___________________________________________
Startup execution:
 loading initial environment
-->

 It just prints:

 Startup execution:
 loading initial environment


 (scilab-shell) calls (scilab-shell-mode) which has a loop which calls
(accept-process-output) until an empty --> prompt appears.
Consequently the whole thing hangs up.

Perhaps the initial header and the input prompt are written to a different
file or unit?

If I comment out the offending lines that cause the hang and run
(list-processes) I get
Proc         Status   Buffer         Tty         Command
----         ------   ------         ---         -------
Scilab      run      *Scilab*      (none)
c:\Programmi\scilab-3.0\bin\Scilex.exe -nw

I used to run Matlab in a buffer some years back and loved it - hope someone
can help me sort this out.

Thanks
