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.
