3.7.5 Communication Control Commands
43) COMMUNICATION CONTROL LD/CD
Function: Communication mode is selected.
Format: Integer C M
Explanation: Contents of the communication control register (CCR) are
rewritten. For the CLD-V5000, the Automatic Status can be
selected ON or OFF. When Automatic Status is ON the Player
returns an “R” upon execution of a command, when it is OFF, it
does not.
The initial value (default value) of the CCR is set to Mode 3. With
this command, it is possible to change the communication mode
as required. If an unsupported mode is specified, an error occurs.
Execution: * CCR = 3 Player’s set to CCR Mode 3; no ‘“R” is returned

currently in CCR Mode 3.)

in CCR Mode 2.)
