Hey there! 

I am trying to make use of an old custumer display which is POSIFLEX PD-2800\320. It uses unnamed matrix which is 20x2 symbols in size and 100x14 pixels in control.

This display does have a DIP-switch with 7 different control modes. I was able to make it work with my python script only in Noritake Control mode so here I am. Despite being able to send some data to the display I still am not able to properly control it using the ESC sequences. I was trying to use these commands [link] from the official website however it never worked properly. 

I was wondering maybe there is another set of command to control the display (brightness, line, symbol number, clear the display)? The display is connected via USB to a Rapberry Pi 3B which runs the python script.

The commands are being set via

>>>s.write(b'\x1B\x5B\x32\x4A') #example

I would appreciate any help regarding this matter.
