User register
The user registers of the terminal can be written by the user program in order to change the characteristics
of the terminal at run-time.
R31: Code word register
• If you write values into the user registers without previously having entered the user code word
(0x1235) in the code word register, these values are only stored in the RAM registers, but not in the
EPROM registers and are therefore lost if the terminal is restarted.
• If you write values into the user registers and have previously entered the user code word (0x1235) in
the code word register, these values are stored in the RAM registers and in the EPROM registers and
are therefore retained if the terminal is restarted.
The code word is reset if the terminal is restarted.
R32: Feature register
The feature register specifies the terminal's operating mode.
