* Check for CTS in the correct register.
* Only do a selwakeup() if we output something.

(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>.)

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.
