Thank you for your advise. I am a teacher in a university in Shanghai
China
 ( My website: oldlinux.org )
The main motivity behind is to learn something about communication
protocol of the most common used FACP. The Ap that I want to program is
experimental and may not going to be practical. Actually I do have
decoded
some part of the ECP.I can now send command in responce to silence the
pancel, silence alarm, on/off (enable/disable) a point, get a report,
get a delta=20
service data. But I think its far not complete yet.
