Hi! Hmm, i don’t think this will work actually but i am no expert. >From what i understand you will send the boot message to the display without a braille driver? I have a serial port display but not a computer with a serial port so i can’t try this either sadly. /A > 30 sep. 2015 kl. 11:22 skrev Tony Baechler <tony@xxxxxxxxxxxx>: > > Hi all, > > I have a question about using a Braille display with a serial console. I don't have access to a Braille display, so I have no way to determine this. Any help and guidance you can offer would be greatfully received. > > If you boot a machine with the serial console enabled and you have a Braille display on the serial port which is configured as the serial console, is there a conflict? To make it more simple, if a boot message is sent out the serial port as plain text with the display connected, does that cause a problem for the display? > > I'm asking because I'm working on a live CD and I would like to enable the serial console. For speech users who still have a serial synthesizer, it's great because you hear the boot message. However, I don't want to cause a problem for people using a Braille display. This would be as soon as the CD starts to boot at the boot loader level, long before brltty would get loaded. Ideally, it would be nice if the boot text would show up on the Braille display, but knowing how sensitive devices are to random characters sent out the serial port, I don't want to create a conflict. For example, the default Talking Arch CD runs brltty at boot and I get random characters from my DECtalk Express, but it locks up my synthesizer and I have to power it off and on to get speech back. I want to prevent something similar for users of Braille. > > Again, I can't currently test this so your help would be very appreciated. I can send the link for the test CD image if you want to try it, but it is currently not booting correctly. > > > -------------------- > Tony Baechler, founder, Baechler Access Technology Services > Putting accessibility at the forefront of technology > mailto:bats@xxxxxxxxxxxxxx > Phone: 1-619-746-8310 Fax: 1-619-449-9898 > > _______________________________________________ > Blinux-list mailing list > Blinux-list@xxxxxxxxxx > https://www.redhat.com/mailman/listinfo/blinux-list _______________________________________________ Blinux-list mailing list Blinux-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/blinux-list
