[hercules-os380] braille

[[e-mail] [hercules-os380]]

I would like PDOS to cater for deaf-blind
users (ie people who are both deaf and
blind) right from the start.

My research says that what is normally
used is a "screen reader" that communicates
with a Braille display.

I'm wondering whether my "BBS" (ie what
you telnet to) should have some sort of
character pacing so that text is only
"displayed" at the rate the Braille reader
can handle, instead of displaying really
fast on the screen and then the user
needs to read the screen.

I think I need to make contact with the
deaf-blind community if it exists.

Of course it exists in almost every city and town.

You can always contact the soc. via the web.

Also take a look at what IBM offers as they have been doing so since the
early 70's and poss. before.

So far I haven't found a good contact on the web.

Anyway, I'm thinking that what PDOS should do
is make use of two extra COM ports and raise
DTR on one of them for "." and the other for "-"
and this triggers vibrations on two different
arms for the user, allowing morse code to be
sent.

Left or right speaker? Or a headphone cable and attach piezoelectric
vibrators?

This group is great for ideas. I am hoping a
deafblind person can provide clarification.

I'm especially thinking of cheap equipment
needed for people in the 3rd world. I'd like
to focus on getting them online. And
exchanging mail via a network probably
based on UUCP.

BTW, I just found that the "F" and "J" keys
have a "groove" so that you can position
correctly for touch-typing without needing
to look at the keyboard. I've been
touch-typing for about 35 years and never
knew about that.

A dimple on these has been standard on typewriters for a long time. But
I just checked my Logitech K120 keyboard, and it doesn't have any
distinguishing features.

I have a new idea.

I'm not sure if qemu runs on a Raspberry Pi,
but Hercules does (I've seen people report
that). So if I make my BBS run on Hercules/380,
manipulating the 2703 serial ports, the
deafblind user doesn't even need a screen
attached, so I think that will be very cheap.

I was thinking about the next step of porting
my "BBS" (ie what is accessible via
telnet kerravon.mooo.com 8888) to S/370.

I need a couple of things. I can live with line
mode for now, but I need a way of doing a
CCW to both the 2703 and the keyboard
(3215) that is non-blocking. If there is no
data available I need to move on to the
next device. It is unfortunate that this
means a hard loop, and it would be good
if there was a way to "yield" the processor,
as there is on the PC.

I'm also wondering whether, when my BBS
becomes more advanced and I wish to do
file transfers, whether a line-mode file
transfer using hex characters would be the
most appropriate thing to do, and that
perhaps "kermit" already does that.

At some point I want my BBS to exchange
mail automatically too, and I'm wondering
whether the file transfer protocol that comes
with UUCP is appropriate for an environment
that includes EBCDIC machines operating in
line mode.

I only need a serial port to do TCP/IP, and
Hercules already does that so long as I
drive a 2703.

I will indeed need to modify the Hercules
hardware to provide some new SVC 120
APIs to drive 2 vibrators though. Any
suggestion on that?

And I think I should probably use PDOS/380
rather than MVS/380 for the comms package,
as that supports me running applications
using the 3215 console.

Que?



https://elinux.org/RPi_Serial_Connection



Its 3.3v but plenty of level shifters available



Also several other GPIO pins. Is there enough for a real CTCA or whatever.

After talking with someone else, I have a new
proposal. Rather than needing operating
system support, I can just have my own
version of "telnet", and when characters
are received from the remote site, my
new telnet can communicate with a
single chip micro board, which in turn
drives two ports, one for the left arm/leg,
one for the right arm/leg.

This would allow deafblind users to
interact with a traditional BBS in morse
code.

The telnet software would send the morse
code for each received character and the
user would need to type that character
to confirm he/she has deciphered the
morse correctly. There would also be an
option to skip the character, e.g. press
ctrl-j.

I haven't been able to find a deafblind
message forum to discuss this.

Yeah, I already found that one, and already
posted something with no response:

http://www.alldeaf.com/threads/deafblind-section.130851/

I think I need to get some deafblind users from
the 3rd world online and into a deafblind
network, polling my BBS, and then the
message groups need to be made available
via the web.

I found that there is an abbreviated version
of English to speed up Braille reading. Very
interesting to see.

I read a newsletter that is published in both
text and Braille. See the difference:

The last time that I worked with somebody needing Braille (early 70's),
I learned that there were many different levels of Braille (more than 7
if I recall correctly) and that there was a special version available to
handle technical information.

Remember that there are only about 64 symbols in braille, and a
particular symbol may have many meanings depending on the context.

I have a couple of blind friends and neither use
braille very much these days. They have sophisticated
speech recognition and readers. Its interesting to
listen to some one operating their phone via voice..

I'm setting higher stakes - I'd like deaf-blind people
to be using and developing PDOS, so voice is not
available. Of course, I would like to cater to blind
people as well, so I guess PDOS should support
that too at some point. But the hardware to
transmit morse sounds like a really cheap option
to me.
