   1 Incomplete list of things that this driver does not yet implement completely or
   2 at all. some of these may not be possible to implement because the hardware
   3 support does not exist. Others may be possible, but the magic control codes to
   4 make them happen are unknown, and some may just need the driver support to
   5 implement them writing.

   7 * Mark/Space parity is not implemented (reported back correctly)
