[PATCH] dz: Fixes to make it work
This a set of fixes mostly to make the driver actually work:
1. Actually select the line for setting parameters and receiver
disable/enable.
2. Select the line for receive and transmit interrupt handling correctly.
3. Report the transmitter empty state correctly.
4. Set the I/O type of ports correctly.
5. Perform polled transmission correctly.
6. Don't fix the console line at ttyS3.
7. Magic SysRq support.
8. Various small bits here and there.
Tested with a DECstation 2100 (thanks Flo for making this possible).
