You posted version 1.09 whitch I tested, but it won't work with old silicon from 1998 (SX18AC/DP 9812 produced in 12 week of 1998). It works fine on SX18AC/DP AB9921AB - produced in week 21 of 1999 or later. So my problem is how to program old silicon with programing pulses longer than 100ms supported in old 1.05 version. I still need version 1.05 of SXkey29L.exe software. ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=168500#m168550 Need assistance?
