Re: [BRLTTY] Very beginner Focus 1 70 cell display installation related question
Dear List, Mario, very thanks your previous helps. My wife buyed a serial cable the home old personal computer, in Debian 12 BRLTTY 6.6 release works correctly the Focus 1 70 display after I turned on the /etc/brltty.conf file the serial port related line (the ttyS0 port related braille-device line). Don't understand why not worked previous an USB cable the display with normal USB port. BRLTTY in serial port mode supports the Focus1 display with typing the perkins keyboard any way? What typing modes are supported? What need me doing table level with development related if would like to BRLTTY supports hungarian language? Basically, in Liblouis component hungarian language are good supported with computer braille, grade 1 both forward and backward translation, grade 2 with forward direction only. Many screen readers use Liblouis I think with Braille typing related, for example I think NVDA and JAWS absolute sure. So, the Focus display are will be a good fallback device when my Alva Satellite display are will break down in the future, me need buying only a serial to usb dongle. Anybody known a recommend a guaranteed working beeper in terms of BRLTTY, with both display and braille input working fine? I used to have a converter with a Prolific Pl2303 chipset, but unfortunately I can't find it anywhere anymore, it's lost. :-(:-( Kind regards, Attila 2024. 04. 11. 16:57 keltezéssel, Hammer Attila írta: Hi Mario, Thanks your answer. An oldest PC my home have a serial port (9 pin ttyS0 port). I will buying a 9 pin serial cable, if the display working, will be buying with the newer PC a serial USB converter dongle, because my newer computer not have dedicated serial port. What type serial cable need? Standard null modem cable, or a general 9 pin serial cable?

Re: [BRLTTY] Very beginner Focus 1 70 cell display installation related question
Hi Mario, Before I brought the display home, my friends looked at it under Windows using the JAWS screen reader based on this guide: https://support.freedomscientific.com/Content/Documents/Manuals/Legacy/Focus/Focus%20Users%20Guide.txt Unfortunately, I don't have Windows, I only use Linux. The following errors are definitely present in the display based on the test carried out on Windows, these are not BRLTTY specific errors, they were caused by the iron teeth of time (this is a very old device): It detects all keystrokes and the wheel, but the keys are very difficult to press, the space also gets stuck. The points stand out nicely, are stable, strong, but when they should retract, they stay out. It's not disturbing, because they fall back when touched, they don't stay out. A close friend of mine only has 64-bit Windows 11 (maybe 2023 h2). Do you think it is possible to connect this display with a USB serial converter via a serial cable? It would be weird if that were the case. In Narrator the online manual I see this modell the supported list (Focus 1 70 cell display), but this is true the 64 bit eco system too? In Linux level I goed back with Ubuntu 14.04 a live test, doed a log file, but both text mode and GUI mode BRLTTY not detected the display (not saved in 5.0 version a log file). What mean the error message with have the previous log files? The 85-brltty udev rules file correct contains device identifier data (vendor and product id).

Re: [BRLTTY] Very beginner Focus 1 70 cell display installation related question
Hello, I doed a detailed test (unfortunatelly without success result) to follow back what versions of BRLTTY worked right previous this old Focus1 modell. I downloaded Ubuntu 18.04.6 Eol supported release (this release contains BRLTTY 5.5 revision). When I used manual BRLTTY start, I used the -ldebug,usb parameter, and use the -L option. The log file with the right english language error message is following: 2024-04-11@09:11:18.207 [brltty] USB URB status error 75: Value too large for defined data type. I see this error message too the BRLTTY 6.6 release in my Debian Bookworm Mate release. I attached the detailed log and sudo lsusb -v result. Me need trying older releases to detect when worked right this old modell with BRLTTY? What version you suggesting if this is the case, or how possible we forwarding the right direction to I have possibility to use this old display with 64 bit architecture in Linux with newer systems? Need a more detailed log? If yes, what options I use when generating the log file in BRLTTY? I am absolute sure newer Focus modells works right with BRLTTY (if it wasn't like that, other Focus display users on this list absolute sure would have already reported it, the strange thing is that I didn't even see a similar error report regarding Freedom displays). Maybe I'm the only one who wants to use an old display as a solution (now me not have better possibility). Does it make sense to open a bug report on the Github bug tracker for this error message? I want to avoid an unnecessary error report if it is an error that cannot be fixed, that's why I'm asking. Attila 2024. 04. 01. 11:40 keltezéssel, Hammer Attila írta: Hi List, I get a very old, but working Focus 1 Braille display (70 cell modell), but I am unable to yet request to working with Linux in console and Orca in Brltty. :-):-) Perhaps have a fatal thing with I am not known yet this display type (I newer worked with Freedom Scientific Focus modells). :-):-) I connect the display with a normal USB cable the right hand USB connection, my braille display I seeing the focus 70 text in Braille, more space character, perhaps a dot 5 point, a 46 dot combination, and a 356 and 12 characters. Lsusb says following this display: Bus 001 Device 008: ID 0f4e:0100 Freedom Scientific Enjoy, not more. :-):-) I have got an Alva Satellite 570 pro modell with works succesfull with Brltty, during I looking the focus display I turned off my Alwa display and restart brltty. Because I newer seeed Focus Braille display, what can I need doing to Debian 12.0 and Ubuntu 20.04 BRLTTY works perfect the Focus display? Because Braille displays are very expensive in Hungary (larger cell modells are more than 800 thousand ft), I would save the Focus Braille display as a backup device later in case my old Alva Satellite 570 display breaks down, but I would like to know for sure how to get this model up and running under Linux later. :-):-) Unfortunately, the Perkins Braille keys stick during use, but you can read perfectly on this model as well. Is this model still serviced at all in the European Union or in the United States? Can you get parts for it? Actually, only the keyboard part should be renovated, the cells are intact, although I could give a complete assessment of the state of the piezo cells if the display was working in Linux. The display is a Freedom Scientific Focus1 70 cell display. I attached a log using the sudo brltty -ldebug -L brltty.log command, compressed in zip format. I see this interesting part the log file (I am using in Ubuntu 20.04 with Brltty 6.5 with Linux 5.15.0-101-generic kernel): 2024-03-31@14:28:26.825 [brltty] checking for braille driver: fs 2024-03-31@14:28:26.826 [brltty] initializing braille driver: fs -> usb: 2024-03-31@14:28:26.850 [brltty] USB URB status error 75: The value is too large for the specified data type 2024-03-31@14:28:26.852 [brltty] USB: endpoint descriptor not found: 00 2024-03-31@14:28:26.852 [brltty] braille driver initialization failed: fs -> usb: Don't surprise, I translated from hungarian to english the data type related hungarian error message.
