False Morel
Many, many, thanks for the time taken to so comprehensively answer my question, it is very much appreciated. It is a pity that I can't get what I'm looking for but at least it saves me a lot of time searching!

programming is ##PROGRAM send
for manual programming you have to be smart enough to know where to put the mdn, min and home sid etc. Look for those things once you get into the programming menu and you will find them. A-key has nothing to do with it.
