FreeBSD Access (Was Re: ultrasonix )

	Some Suns go to the serial port if the system is started
up without the keyboard/mouse unit attached.  I imagine some P.C.
displays can tell if the monitor is disconnected, but there is no
return signal for your average VGA-style monitor port so the
system doesn't know one way or the other whether the monitor is
on, off or connected.

	Also depending upon the hardware, you may get that
functionality if the video card is removed completely.  Other
system boards won't work at all if you do that.

	You pays your money and takes your chances.

	Other than the fact that I wasted a lot of time I didn't
really have in trying to figure out how to make the serial
console work, I had a load of fun.

	Finally, if you happened to read my response in which I
mentioned the Braille and Speak, I wrote that before reading
Janina's message so that confirms what I suspected.

	Basically, any access device you want to use that looks
like a vt100 is fine.

	The FreeBSD boxes I worked on this last Summer are
replacements for our primary and secondary domain name servers,
the work station I am sending this email from, and yet another
domain name server for a department on our campus that wants as
fail-safe a dns system as possible.

	I definitely give FreeBSD high marks for accessibility so
long as you don't expect to find a screen reader right on the
system.  As far as I know, there is none.  It is the serial
console I really like and the security concern shown in the setup
and configuration options.

	Of course, once you have a FreeBSD box up and running, it
acts like Linux or any other UNIX box.  You will like most of
what you find and probably find that a few minor things are
different from other UNIX systems you have used.  That makes
FreeBSD no different in that respect from AIX or AT&T versus
BSD-style UNIX.  It is like American English from different parts
of the country or from the UK.  It's all English and one just has
to learn the idiosyncrasies of the particular system to get the
most good out of it.
