>(see attached text file)

O.K., i made some more tests and usb logs.
The attached text file shows all commands from SonicStage start to SonicStage 
close 
There seems to be a general command to access TOC data, there are several 
comments
in the text file to describe my interpretation of some commands.

regards,
Thomas



# downloading 1 Track with SonicStage on MZ-NH1
# - starts at opening SonicStage and ends on closing SonicStage
# - download part and reading track list are not displayed, we already know this
# - known commands are replaced by their function names in libnetmd.py
# - some commands are grouped with their corresponding open/close commands to make it easier to read
#
# - following commands are replaced, too
#   these are not implemented in libnetmd, it´s just a sample of how they could be implemented
