Hello. I am the lead developer for gentoo linux's accessibility team[1], and I am on the development team for the speakup screen reader [2]. I received these addresses from Samuel, and Chris and Kirk are the other developers on the speakup team. Currently, speakup is using direct hardware access to communicate with serial ports. Doing so, however, has limitations since we are hard coding port addresses and IRQ numbers. For example, we have a user right now who is wanting to use a PCI Express serial card for his synthesizer, but the port and IRQ are not standard, so speakup is unable to use it. He says that the kernel does recognize the card however. What I would like to discuss is how we can access ttys from kernel space. If we could do this, it would definitely make things much easier for us in speakup. For reference, our git repository is at http://linux-speakup.org/speakup.git. We are looking to write another .c file similar to serialio.c but using ttys or some other way to access the serial ports which works better than hard coading ports and IRQs. We found another example of attempting this on the web [3], but this doesn't work any longer according to the thread. We need to be able to access the ttys as early as possible in the boot sequence. Any help, suggestions, or guidance you could give us would be greatly appreciated. Thanks much, William [1] http://www.gentoo.org/proj/en/desktop/accessibility [2] http://linux-speakup.org [3] http://www.linuxquestions.org/questions/programming-9/accessing-tty-in-kernel-space-596538/ -- To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
