Re: EST3 Communication Protocol

["Robert L Bass" <robertbass1@xxxxxxxxxxx>]

I agree with Mr. Sloud about contacting GE on this.  They're tight-lipped about certain things but with a legitimate need for
training people who might later contribute to the industry they might be willing to help.  Let me know if you don't get any help
from them.  I have some friends there who might be able to open a door for you as long as the need seems legitimate to them.

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
service data. But I think its far not complete yet.
