IMPORTANT :
in order to manage any error messages correctly with the PLAY File (command
code 50H) and PLAY File 2 (command code 51H) commands, DINplayer will check for the requested MP3 file
with a consequent delay of 800/900 mseconds whilst the reply is sent.
When using the PLAY File B (command code 56H) and PLAY File 2 B (command code 57H) commands,
DINplayer will not check the memory and will immediately send an interpreted command message and the
track will begin to play once the reply has been sent. The following errors are not managed with these
commands: "File not found" (error code 32H) and “PLAY file failed" (error code 33H).
