| Incomplete list of things that this driver does not yet implement completely or | |
| at all. some of these may not be possible to implement because the hardware | |
| support does not exist. Others may be possible, but the magic control codes to | |
| make them happen are unknown, and some may just need the driver support to | |
| implement them writing. | |
| * Mark/Space parity is not implemented (reported back correctly) | |
| * IXANY flow control mode is not implemented (flag ignored completely) |
