Hello Mark and Tony,

thank you for your replies and the valuable links to the FAQ.

Good to know that networking is available even if the empeg is in the sled.
And thank you for your cool program empegface.
I will play around with it when my empeg is assembled again.

The VFD of my empeg broke and i managed already to buy a replacement VFD and solder out the old one
but until now i didn´t have time to complete the repair.
The empeg is sleeping partly disassembled in its bag now until i have exchanged the display.
After that it will be installed in the dash like in the good old days.

I knew about the listed serial commands but i thought there were more commands i can get the RDS stream with.
With the search function i found the link of a member called alex25 concerning his TMC script but the link to http://www.empeg.homelinux.com/TMC.zip is dead.
It was posted around July 2004 and alex25 did his last post in March 2006.

Do you know where i can get his script or some other code?
Or is there some kind of service manual or other documentation about the deepest internals available?
As a Linux Admin i'm very advanced in shell scripting but i'm a rookie as far as C++ is concerned.
But with as much information as possible i could give it a try.

Thanks for your help so far, i appreciate it very much.

Best regards,
Andrés
