RE: DSP-AX1

["Andy Powell" <Andy@xxxxxxx>]

Sorry just 2 points to add/ammend

When I say ASCII char n eg Send 7 (ASCII CHAR 7) I mean (in BASIC) CHR$(7)
(Just in case it wasn't clear). Also the "Turn volume up" bit
should read
as below:

For example to turn the volume up:

Send STX (ASCII CHAR 2)
Send 0   (ASCII char 0)
Send 7   (ASCII Char 7)
Send 10  (ascii char 10)
Send 1   (ASCII CHAR 1)
Send 10  (ascii char 10)

Finally send ETX (ASCII CHAR 3)

The volume should turn up!

After you've sent this and the volume has turned up the unit should send
some more data back to the PC -  this is the REPORT part - tells you what
it just did.. I haven't looked at it yet.. more soon..
