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)
8 * IXANY flow control mode is not implemented (flag ignored completely)
