Yes, of course, thanks for warning. Actually, for my needs it makes more sense to get a bluetooth adapter instead of a DB9 socket, and just do nullmodem over BT. I have done this with the minimig using an rs232/BT adapter, and one can get cheap BT adapters (controlled using AT commands) that I believe can be hooked up directly.
