I have a LANC interface operating on a PIC16F876A. It uses the T1 timer 
and a INT pin
to receive and jam the control. The last time it was used was over 3 
years ago, to control
SONY VCRs.

I can splice off a piece of it, and you will probably be able to jam the 
signals. I didn't use many
LANC codes in my routines, but I also have the complete specs for SONY 
LANC controls
someplace. Maybe James might wanta make a page for it, as it is 
confusing at first.
