CIS, weren't actually used anywhere (other than the generic PC Card
code when certain variables are defined). They aren't used in NetBSD
either. Make things simpler by removing them. Change PLANEX_2 to
PLANEX and tweak wi and owi to use that instead. The PLANEX id seems
to actually be pci ID assigned to planex, not its pcmcia id. Ooops.
I don't know if this is a reporting error from where this entry came
from, or if it is a mistake on PLANEX's part. I suspect the latter,
as ACTIONTEC and NEWMEDIA made the same mistake (although new media
may be because it uses an advansys chip inside). Make a note of this
in the file. The 0xc entires may be JEITA assigned, so note that as
well.
# This leaves just 3 entries that are totally unknown: airvast, archos

This driver implements "unaddressed listen only mode", which is what
printers and plotters commonly do on GP-IB busses.
This means that you can capture print/plot like output from your
instruments by configuring them as necessary (good luck!) and
cat -u /dev/gpib0l > /tmp/somefile
Since there is no way to know when no more output is comming you
will have to ctrl-C the cat process when it is done (that is why
the -u is important).
before entering ng_netflow. In this case it will have not NULL m_pkthdr.rcvif.
However, it will enter ng_iface soon with another index. So let in_ifIndex
value configured by user override m_pkthdr.rcvif.

all reserved, as the lisence makes clear), and strike the third clause
(now this is a 2-clause liberal BSDL as are the rest of files I hold
copyright over).
The presence or absence of a keyboard does not change whether an
UART is designed as a keyboard port or not and thus whether we
can use the port as a TTY or not.
We now call sunkbd_attach() even when we didn't previously find
a keyboard. Emit a useful message stating that no keyboard was
found, but don't do anything else.

overhead associated with with malloc and reduce the memory
consumption associated with each new state.

sb_state shouldn't be erased, when socket buffer is flushed by sorflush().
When sb_state was bzero'ed, a recently set SBS_CANTRCVMORE flag was cleared.
If a socket was shutdown(SHUT_RD), a subsequent read() would block on it.

o Disable ofw_console(4), sab(4) and zs(4).
sab(4) and zs(4) are disabled because the hardware controlled by
them is handled by uart(4)+puc(4) and the latter combination is
functionally complete and up to date.
ofw_console(4) is disabled because it doesn't claim the device it
controls (through OFW) and thus interferes with puc(4)+uart(4),
which has sufficient knowledge to extract the necessary information
from OFW to setup the console. Put differently, ofw_console(4) is
not a proper device driver and can only do harm. Its functionality
is completely handled by uart(4).
This commit makes uart(4) the default driver for serial ports.

engineering the pending interrupt sources from the current
state of the controller. For channel A we can always read the
interrupt pending register (RR3). For channel B we can read
the interrupt vector register (RR2) because it contains the
modified vector and thus includes the interrupt source.
Since we currently need puc(4) for the Z8530, we know that
the interrupt handler for both channels will be called and
thus that RR3 will always be read at least once, even if ch A
has no pending interrupt.
NOTE: The modified interrupt vector has no value that represent
a lack of pending interrupt for channel B. That is, the
value read when no interrupts are pending is the same as the
value for the special receive condition. Fortunately, we don't
actually have to depend on that interrupt source. This does
mean that we need to properly handle the overflow condition,
when we read received character from the chip.
o The DSR signal is represented by the SYNC bit in the external
status register (RR0). We now properly track DSR.
o It's save to enable the external/status interrupt source. We
now get interrupts when line signals (DSR, DCD or CTS) change.
Problems fixes:
o interrupt storms.
o blocked open(2).
o lack of (hardware) flow control.
o unable to report DSR.
