Update of /cvsroot/src/sys/dev/ic
In directory netbsd1:/var/slash-tmp/cvs-serv6046

Modified Files:
	z8530tty.c 
Log Message:
Rearrange open sequence to make sure we catch all line status changes.
Make sure we turn on DTR and/or RTS as appropriate during open.
Rearrange close sequence so the tty is flushed before turning off interrupts.
Deal with `softcar' and the console device by silently asserting CLOCAL and
|HUPCL, as in com driver.
Do *not* fiddle with DTR when changing the line speed.
Make sure we update the tty's carrier status when CLOCAL or MDMBUF is changed.
Only change rr1 when we actually need to turn on or off TIE.
