Hi,
what about this one as a start :
http://www.koeniglich.de/fhz1000/fhz1000.htmlIt's a Perl script and it is quite easy to integrate Perl scripts into Pluto (you just connect to DCE via text interface and there you go)...
Is there any more experienced Perl programmer around ? I can help with knowledge what needs to be done, but cannot program Perl well...
Such solution could serve as a good starting point also for other rs232 based home automation interfaces. Even better - with experienced Perl guy also Perl could be integrated into Pluto - just as now Ruby is...
HTH,
regards,
Rob.
