I need some help here. I've got a pair of 635 units. One that dates back about a year and a half and one that I just got. Code that works fine on the older unit doesn't work properly on the newer one. For example: I write four full lines with four subsequent command 31's. The first line appears but the others don't. The unit works as per the 635-Wintel tool. So the real question is can you give me (us) a much more detailed explanation of the changes in the firmware?
