“INF” status requests and responses
The INF commands offer requests for different types of information on the disc. CDs and DVDs work differently, so the commands and
replies are different.
Structure for Audio and Video CDs
Note that the first parameter byte (following the “c” or “s” command/status byte) is lowercase on the CD status information.
