This is the main handler of the MMI profile container

Parameters : fb_in_offset   First byte in the input container
             fb_out_offset  First byte in the output container
             db_address     Number of the database to use
             con_len        Length of container in bytes (min.32)  

Example : The terminal is configured to be on input and output byte 64,
          32 bytes allocated  and database to communcate with is 51:
          fb_in_offset  = 64
          fb_out_offset = 64
          db_address    = 51
          con_len       = 32

The function block handles one complete container in one scan. If read index,
FC111 is called.
If write index, FC112 is called.
Note that the control byte is not set until next scan, to avoid timing problems
