Update of /a/cvsroot/src/sys/arch/hp300/dev
In directory pain.lcs.mit.edu:/b/tmp/cvs-serv479

Modified Files:
        dca.c 
Log Message:
Several changes:
        * Reset the card on "fresh open" as a sanity measure.
        * Use the "secret bit" to enable interrupts.
        * Make some parts look/behave like their cousins in dev/isa/com.c
        * Set the FIFO threshold based on line speed.
        * Be a little more informative when port is attached.
        * Implement TIOC{G,S}FLAGS; ttyflags now works.
First two items prevent deadlock on some systems (notably the 380,
425, and 433) which some people have been reporting.  Use of the
"secret bit" seems to be safe on systems which don't need it.  Changes
tested on a 319, 340, 345, and 380.
