 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.
