Huh, I see joerg_rw started to play with at_commands. I've worked with them for years, so for the first time, probably, I know his discoveries for quite a long time. Damn, never though that day will happen

Seriously though, I agree that it's very nice to document it here - it's true that at commands are not very popular in scripts. Thinking about that, I have no idea why - for me (and anyone, who played with GSM modems and phones acting as modems for other, strange purposes) they're quite natural.
