[En-Nut-Discussion] Using RS485 With Ethernut 2

[JayOmega]

I'm building with the Configurator, i.e. from the pull down menu I select
"Build->Build Nut/OS".

I have the following related to uart1 in 'include/cfg/arch/avrpio.h':

#ifndef UART1_HDX_BIT
#define UART1_HDX_BIT
#endif

If I type 'make all' from a DOS command line within nutBuild (...I'm not
sure this is how it should be done...) I get multiple errors associated with
UART_HDX_PORT and UART_HDX_DDR.
