- Speakup project home: http://www.linux-speakup.org
- Mailing List: speakup@linux-speakup.org
- Speakup is a kernel based screen review package for the linux operating
- system. It allows blind users to interact with applications on the
- linux console by means of synthetic speech.
- Currently, speakup has several issues we know of.
- The first issue has to do with the way speakup communicates with serial
- ports. Currently, we communicate directly with the hardware
- ports. This however conflicts with the standard serial port drivers,
- which poses various problems. This is also not working for modern hardware
- such as PCI-based serial ports. Also, there is not a way we can
- communicate with USB devices. The current serial port handling code is
- in serialio.c in this directory.
- Some places are currently using in_atomic() because speakup functions
- are called in various contexts, and a couple of things can't happen
- in these cases. Pushing work to some worker thread would probably help,
- as was already done for the serial port driving part.
- There is a duplication of the selection functions in selections.c. These
- functions should get exported from drivers/char/selection.c (clear_selection
- notably) and used from there instead.
- The kobjects may have to move to a more proper place in /sys. The
- discussion on lkml resulted to putting speech synthesizers in the
- "speech" class, and the speakup screen reader itself into
- /sys/class/vtconsole/vtcon0/speakup, the nasty path being handled by
- userland tools.
- Another issue seems to only happen on SMP systems. It seems
- that text in the output buffer gets garbled because a lock is not set.
- This bug happens regularly, but no one has been able to find a situation
- which produces it consistently.
- Patches, suggestions, corrections, etc, are definitely welcome.
- We prefer that you contact us on the mailing list; however, if you do
- not want to subscribe to a mailing list, send your email to all of the
- following:
