mycroft 4bfd7749ad Various:
* Check for CTS in the correct register.
* Only do a selwakeup() if we output something.
* Don't make assumptions about what TTYDISC does.

mycroft 5b37a8fded Handle BREAK correctly when not entering DDB. 1995-06-04 20:50:14 +00:00
mycroft 38847d04c0 Add an input FIFO, and fix several flow control problems. Based on code from
Felix A. Croes.

jtc d045544ebd Changed ns82450 to ns8250 and dropped ns82550 from probe console messages. 1995-06-01 21:26:51 +00:00
mycroft addaff473b Only use the `no pending interrupt' bit in the IIR; the other bits
are too unreliable on clone chips.

cgd c821cb684a (1) conditionalize debugger usage in comeint with DDB, not COMCONSOLE;
latter would lead to undefined symbols if DDB not defined.
(2) check for break on console, and therefore debugger entry (if ddb
	in kernel) earlier, so that the device doesn't need to be open.
(3) return immediately after breaking into the debugger in comeint().
(4) only do the normal character input routine in comintr if receive
	mask yeilds _EXACLTY_ LSR_RXRDY.  if there's only a receive
	error, or there's a receive error _and_ a received character,
	do comeint().
(former two by me.  latter two from Bob Baron <rvb@cs.cmu.edu>.)

hpeyerl c9319ad5c4 <break> --> ddb if defined(comconsole).
(if you have a serial console and you hit break, you get ddb).

cgd 8a640328ed clean up several ISA device interfaces: autoconfiguration, header
inclusion, and interrupt configuration.  more work still needs to be done,
but it's getting better...

mycroft 95c5c4f79f Most of the console functions return void. Also change interrupt logic
slightly.

cgd 3a7bbb1acd lip service to making ISA support machine-independent. This is the first
round: moving the drivers into a machine-independent directory.
Some drivers (e.g. fd.c) not moved because they use other pc features (e.g.
CMOS settings), and none of the non-driver files moved, because they're
still pretty much PC specific.  eventually (when other ports with ISA
busses really start using this code), more 'high-level' ISA support will
live here.

cgd c6b399cce8 add AST-style serial multiport support, from Roland McGrath
<roland@@frob.com>.  Needs light clean by Mr. I386, but mostly
OK.  For some reason, Bad Things (TM) happened on the last cvs commit.
