Volume Control

[IamDan77]

Ive posted this in the HA forums but not sure how often you visit there

Excellent work!! I have an Azure 751r that I would love to control over RS232 (currently using broadlink) I had a go at butchering your code and adding in the commands I require (Im a mechanic so programming is not my forte). I think Ive changed the correct commands. However I cant see in your code where I can change the volume up and down command/replies.
How would I go about changing them? Thanks in advance

Also your sound modes. Ive had a look through the documentation and cant find where you get 25 from in the amplifier commands
