I can now execute motion commands in a basic program using the direct serial link. Getting data out of the basic program is also easy, but without a properly documented serial protocol it is hard say what is going on. Bottom line writing to the first defined variable works good, but reading other variables some times send commands to the first variable executing motion sequence 1.

I will be implementing a direct serial motion system, but I will be reading and writing to the variables directly to start motions and to find out when they are complete. For this the stock 9600 baud rate will be good enough.
