at least the /MCLR had 5,1V when I measured it, even with the long cable. Maybe, if that's the problem, it can be solved just by adding a buffer (transistor, etc). But anyway, my ICD stopped working. It was working perfectly and then bam, can't connect. I'll keep trying hjf On Fri, 21 Jan 2005 17:47:12 -0500, Josh Koffman wrote: > I think an important point might be that the ICD2 is using some RS232 > signals for uses other than that which they were designed for.
