Werner,
Thanks for the info it was very helpful. I would have replied earlier but this system would only let me post one message a day.
Dumb question. I don't have to run this is a router do I? I can still compile and run 'C' code and Python?
"2. no clue ." I now know why this was confusing. After reading available material I found the rear UART port by default in Debian is activated as a serial port. I.E. login. so that would eliminate the need to access the debug port next to the Ethernet adapter I.E. keeping the case open.
Thanks,
Ken
