WHAT IS IT:
Port/adaption of the betty terminal emulator (https://code.google.com/p/betty/) for 
the onyx international boox m92 e-book reader.

INSTALLATION:
Standard install of the binary adds a shortcut in the Applications menu.
1. Copy the directory containing the installer to your boox.
2. On the boox browse to the installer directory
3. Click on install.oar, wait for the device to reboot.

COMPILE SOURCES:
1. Setup the SDK toolchain for the boox m92 (see e.g. 
   https://wiki.mobileread.com/wiki/Boox_M92_software_development).
2. Get betty (https://code.google.com/p/betty/)
3. To compile libbetty you have to add the path to your arm-linux-cc compiler
4. Go to the source directory, edit betty.pro to point it to the libbetty.a library

USE:
Type commands with the onscreen keyboard. Unfortunately not all keystrokes 
are available with the onscreen keyboard. For this reason there are several 
buttons to the left of the terminal screen. The buttons allow to insert:

Button	Function 
DEL	Send the Delete key (Char 0x7f)
Ctr-C	Send the SIGINT signal to the running process (Char 0x03)
ESC	Send the ESC key (Char 0x1b)
Ctr-...	Send a Ctr sequence, next character is combined with the Ctrl-key 
	(Chars 0x00-0x1f)

With these buttons and the on screen keyboard the complete ASCII table can 
be send, for reference see the table below.

ISSUES & BUGS:
- Input is frustratingly slow (dunno how to speed it up)
- Last line of the terminal widget is somehow not properly updated on the screen
  sometimes this renders the last line unreadable
- Interface is ugly 

TODO:
- It would be nice to have several terminals at the same time in a tab widget
