Briefly I need to send text (command lines) to a vmusic2 module from a PIC. 
The vmusic2 will have a number of directories containing .mp3 files. Each directory represented by a single button. IE Sw1 = directory sw1 sw2 = directory sw2 etc up to approx 20. 
Most commands will be same regardless 

EG stop playing =VST (carriage return)
Cd to root = CD..
and play all files = VPR
The only "different on will be CD swx where x = directory details. 

Cheers
Ian Burrows
