   Any text mode using tones you should be able to tune with your ear and use   
   whatever text to braile device you can use.   
       
   RTTY is a good starting point then move from there.   
       
   Monitoring RTTY is to my mind a good idea. If you feel mixed characters is   
   because RTTY is straight out with no error corrections.   
       
   To decode the tones have to be high pitched, around 2300 hz
