[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). [akpm@osdl.org: fix typo] Signed-off-by: Maciej W. Rozycki <macro@linux-mips.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
