Harry,
Thanks for pointing out that typo. If I put it on the Playground, I'll correct it there. (Enjoyed your blog, BTW)
I should also include this reference - ftp://ftp.x10.com/pub/manuals/cm17a_protocol.txt.
(There are also a lot of "PC" CM17A applications out there, but the only one I found for a micro which was in ASM and used a MAX232.)
jcgalvezv, I'm curious, so you remove the daughter board from the TM751 receiver and use the digital outputs on it?
Thank you both for your feedback.
