Note: This entry is added as this is there was no mention of any phones
in the list. This entry might have people try the driver against their
device.
The Sony Ericsson phone provides an OBEX stack on further CDC
interfaces. Umodem wrongfully assumes that it is the driver for this
interface. This is due to a bogus implementation in the umodem driver
when searching for the data interface. This should be read from the CDC
descriptors. Also, more of this should happen in the probe instead of
attach.

- Change the ddb(4) commands to be more useful (by thompsa@):
- `show ttys' is now called `show all ttys'. This command will now
also display the address where the TTY data structure resides.
- Add `show tty <addr>', which dumps the TTY in a readable form.
- Place an upper bound on the TTY buffer sizes. Some drivers do not want
to care about baud rates. Protect these drivers by preventing the TTY
buffers from getting enormous. Right now we'll just clamp it to 64K,
which is pretty high, taking into account that these buffers are only
used by the built-in discipline.
- Only call ttydev_leave() when needed. Back in April/May the TTY
reference counting mechanism was a little different, which required us
to call ttydev_leave() each time we finished a cdev operation.
Nowadays we only need to call ttydev_leave() when we really mark it as
being closed.
- Improve return codes of read() and write() on TTY device nodes.
- Make sure we really wake up all blocked threads when the driver calls
tty_rel_gone(). There were some possible code paths where we didn't
properly wake up any readers/writers.
- Add extra assertions to prevent sleeping on a TTY that has been
abandoned by the driver.
- Use ttydev_cdevsw as a more reliable method to figure out whether a
device node is a real TTY device node.

- Minor update for Mauritius (which I don't understand)
- Syria goes to DST at 1 November instead of 1 October.
- Niue is now located at the right side of the equator.
This was located in the ubsa driver, but should be moved into a separate
driver:
- 3G modems provide multiple serial ports to allow AT commands while the PPP
connection is up.
- 3G modems do not provide baud rate or other serial port settings.
- Huawei cards need specific initialisation.
- ubsa is for Belkin adapters, an Linuxy choice for another device like 3G.
Speeds achieved here with a weak signal at best is ~40kb/s (UMTS). No spooky
STALLED messages as well.
Next: Move over all entries for Sierra and Novatel cards once I have found
testers, and implemented serial port enumeration for Sierra (or rather have
Andrea Guzzo do it). They list all endpoints in 1 iface instead of 4 ifaces.

This changes from a line discipline to the tty_hooks mechanism. Data will come
in directly via rint_bypass and sent to the peer node in a single mbuf.
As line disciplines are no longer used a new netgraph command called
NGM_TTY_SET_TTY is used to attach the tty. This takes a pointer to to the open
file descriptor of the tty and registers the tty hooks. When the tty disappears
the node will shutdown.

Update referenced example to include unistd.h per manpage.
Update example to be more style(9)-ish, silence warnings and add
FreeBSD id to the source file.
- Document the minor(3), major(3) and makedev(3) macro's. They also
apply to umajor() and uminor() in the kernel, but hopefully we'll sort
that out one day.
- Briefly dev2unit() inside the make_dev(9) manual page, since this is
now the preferred macro to obtain character device unit numbers inside
the kernel.
- Remove the device_ids(9) manual page. It contains highly inaccurate
information, such as a description of the nonexistent major().
To prevent any further confusion about device minor and unit numbers,
we'd better just refer to device unit numbers. Many people still think
the numbers we show inside devfs have any relation to the numbers passed
to make_dev(9), which is not the case.
Discussed with: kib
It seems this script was broken because of the SYSINIT changes and a
rather awkward variable initialisation. For some reason the
make_device_driver.sh script is also broken, related to BUS_SETUP_INTR.
I have no experience with FreeBSD's interrupt handling, so I hope
someone else is willing to take a look at that shell script.

years by the priv_check(9) interface and just very few places are left.
Note that compatibility stub with older FreeBSD version
(all above the 8 limit though) are left in order to reduce diffs against
old versions. It is responsibility of the maintainers for any module, if
they think it is the case, to axe out such cases.
This patch breaks KPI so __FreeBSD_version will be bumped into a later
commit.
This patch needs to be credited 50-50 with rwatson@ as he found time to
explain me how the priv_check() works in detail and to review patches.

As reported by several users on the mailing lists, applications like
screen(1) fail to properly handle ^S and ^Q characters. This was because
MPSAFE TTY didn't implement packet mode (TIOCPKT) yet. Add basic packet
mode support to make these applications work again.
