Ahh, but didn't Kyosti or Greg delete all the command functions from all the chip driver modules? I think that all the drivers had "command" functions that said "None at this time", but removing that code was one of the things I had to do to make my 2.7.0 driver "cvs"... So I don't think any of drivers even have a command function any more. Which is not an argument for removing the function to access them, but it seems odd that it would be an inline function in that case... :v) Mark D.
