I found an interesting article on how SMS came about. Basically SMS was never intended to be a useful service – just something else to be added to the GSM specification in case it was ever needed. It was never designed for Person to Person communications – just for machine to person communications. Things like saying there is a voice mail message available. The article is interesting but it is very hard to read because of all the acronyms.

This aftrenoon I have been busy programming rather than working on the plane. The code is getting to be quite usable. Not much error checking, but the functionality is getting there… Once everything is working I can then add the error checking.
