+This page shows all commands transferred during the upload of an SP track. The Replies are cut of the command echo. If not especially stated, they return with "09 ACCEPTED" and a sucessful read result (if applicable).
+Only the VENDOR SPECIFIC command (it's just one) related to uploading the track.

+This is an invalid command, yet the RH1 accepts it. The info_block_reference_path should refer to an info block, not to an descriptor. I don't know what the byte offset 8 is relative to.
