scw	54f42f17fc	Don't bother spinning in the console 'putc' routine for the transmitter to become idle; it actually doesn't matter as the chip takes care of this for us. It would also spin endlessly in certain circumstances during shutdown. While I'm here, (finally) add code to allow sending BREAK characters.	1999-11-28 12:23:18 +00:00
scw	ba922d31d8	Re-work the Tx side to avoid calling into the tty layer at interrupt time. This was the cause of the 'mmu fault' panics seen by several people, as the Tx interrupt is at a higher priority that spltty().	1999-08-01 09:35:05 +00:00
scw	94719c7b9a	New MI front-end for the Cirrus Logic CD240[01] Multi-protocol Communications Controller. This is still a work in progress, but it is functional enough to be usable.	1999-02-13 17:05:19 +00:00

Don't bother spinning in the console 'putc' routine for the transmitter

to become idle; it actually doesn't matter as the chip takes care of
this for us. It would also spin endlessly in certain circumstances
during shutdown.

While I'm here, (finally) add code to allow sending BREAK characters.

Re-work the Tx side to avoid calling into the tty layer at

interrupt time. This was the cause of the 'mmu fault' panics
seen by several people, as the Tx interrupt is at a higher
priority that spltty().

New MI front-end for the Cirrus Logic CD240[01] Multi-protocol

Communications Controller.

This is still a work in progress, but it is functional enough to
be usable.
