+ Enables console output on a braille device connected to a 8250
+ serial port. For now only the VisioBraille device is supported.
+
+ To actually enable it, you need to pass option

+This file is intended to give you an overview of the default keys used
+by speakup for it's review functions. You may change them to be
+anything you want but that will take some familiarity with key
+mapping.
+
+We have remapped the insert or zero key on the keypad to act as a
+shift key. Well, actually as an altgr key. So in the following list
+InsKeyPad-period means hold down the insert key like a shift key and
+hit the keypad period.
+
+KeyPad-8 Say current Line
+InsKeyPad-8 say from top of screen to reading cursor.
+KeyPad-7 Say Previous Line (UP one line)
+KeyPad-9 Say Next Line (down one line)
+KeyPad-5 Say Current Word
+InsKeyPad-5 Spell Current Word
+KeyPad-4 Say Previous Word (left one word)
+InsKeyPad-4 say from left edge of line to reading cursor.
+KeyPad-6 Say Next Word (right one word)
+InsKeyPad-6 Say from reading cursor to right edge of line.
+KeyPad-2 Say Current Letter
+InsKeyPad-2 say current letter phonetically
+KeyPad-1 Say Previous Character (left one letter)
+KeyPad-3 Say Next Character (right one letter)
+KeyPad-plus Say Entire Screen
+InsKeyPad-plus Say from reading cursor line to bottom of screen.
+KeyPad-Minus Park reading cursor (toggle)
+InsKeyPad-minus Say character hex and decimal value.
+KeyPad-period Say Position (current line, position and console)
+InsKeyPad-period say colour attributes of current position.
+InsKeyPad-9 Move reading cursor to top of screen (insert pgup)
+InsKeyPad-3 Move reading cursor to bottom of screen (insert pgdn)
+InsKeyPad-7 Move reading cursor to left edge of screen (insert home)
+InsKeyPad-1 Move reading cursor to right edge of screen (insert end)
+ControlKeyPad-1 Move reading cursor to last character on current line.
+KeyPad-Enter Shut Up (until another key is hit) and sync reading cursor
+InsKeyPad-Enter Shut Up (until toggled back on).
+InsKeyPad-star n<x|y> go to line (y) or column (x). Where 'n' is any
+ allowed value for the row or column for your current screen.
+KeyPad-/ Mark and Cut screen region.
+InsKeyPad-/ Paste screen region into any console.
+
+Hitting any key while speakup is outputting speech will quiet the
+synth until it has caught up with what is being printed on the
+console.

+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 one issue we know of.
+
+It 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:
+
+okash.khawaja@gmail.com, w.d.hubbs@gmail.com, chris@the-brannons.com,
+kirk@reisers.ca and samuel.thibault@ens-lyon.org.
