If you're interested in doing this, I'm sure we can work this out.

Correct. While the STK commands are thorougly documented in the specs, the AT commands are device-specific.
I can collect the Calypso-specific information you need -- if you want to work on that.


May be there should be some daemon to STK - like fso-stk and runnable GUI for menu, because it should respond to STK events - incoming message from bank etc

what we need is documentation, how restricted is NDA - and for who? people outside of company?
