With uart(4) default, change /dev/cuad# to /dev/cuau# and
sio# to uart# so that out-of-the-box FreeBSD is consistent.

As previously discussed, add the svn:executable property to all scripts

Add an example of how to set up a 3-wire serial terminal.
Usually, getty(8) does the trick, but if you just need a
serial console without getty(8), here's how.

Unify the ci/co variables now that the the tty drivers now use the same
character for both.

Catch up with PHK's sio(4) rework [sys/dev/sio/sio.c rev. 1.456].

Remove the requirement for the FreeBSD keyword as it no longer
makes any sense.

Discussed with: dougb, brooks
MFC after: 3 days

Mark scripts as not usable inside a jail by adding keyword 'nojail'.

Some suggestions from: rwatson, Ruben de Groot <mail25@bzerk.org>

Catch up with 1995(?) for modem speeds (use 57600 instead of 115200 for
the example host to modem speed).

When resetting to defaults, reset drainwait to the current default pf
`sysctl -n kern.drainwait` instead of to the boot-time default of 300.

Fix style bugs:
* Space -> tabs conversion.
* Removed blanks before semicolon in "if ... ; then".
* Proper indentation of misindented lines.
* Put a full stop after some comments.
* Removed whitespace at end of line.

commit.

Style clean-up:

* All variables are now embraced: ${foo}

* All comparisons against some value now take the form:
[ "${foo}" ? "value" ]
where ? is a comparison operator

* All empty string tests now take the form:
[ -z "${foo}" ]

* All non-empty string tests now take the form:
[ -n "${foo}" ]

Back out last brain blip.

Change examples for Cyclades cards (c -> c0) to fit with reality.

Fixed the Cyclades and Digiboard port numbers.

Revert $FreeBSD$ to $Id$

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

Added support for Cyclades and Digiboard devices.

Another round of spelling fixes.

This is a purely cosmetic clean up. Fix many cut and paste problems that
had turned tabs into spaces.

Add drainwait option examples

cua*0? --> cua*a?

Now rc.serial used for initial setup of serial lines
