Actually you define it in Makedefs, but running
nutconf copies Makedefs.icc to Makedefs.

At this place NUTDEBUG is used by your application only.
So it may or may not be used.

For debugging use devDebug1. It uses polling,
not interrupts and is safer.

Are you aware that UART1 is not attached
to the DB9. It is available at the expansion
port but requires an additional RS232 driver.
As a lucky owner of Ethernut 2, you can set
jumpers to have both UARTs available, but
you need a special DB9 adapter.

Lots of, via telephone line as well as GPRS. Sometimes
problems appear with some special settings on the
provider's side. Without tracing (debugging) you are
lost.

You are on the right track. Write a simple application and
try to get some output on UART1 first. Then go back to
PPP debugging.
