Full screen data transmission
In this mode the entire screen data is send to the emulator.
The data is send in the original sequence as it is written to the screen.
However during scrolls the EPIS buffer is quickly overflown and some
messages could be lost.
Software extraction of the messages on the emulator end is
posible but not entirely reliable. Model 1.3 addressed this issue
and 2 other modes of operation were introduced.
