[En-Nut-Discussion] RS485 ETHERNUT3

[ml]

hi 

in usartat91.c the hdx_bit doesn´t work because it is old code for avr.
i change it to the right port functions (outr .. etc) so it toggles the 
port bit. but when i enable the us_txempty interrupt 
(hdx-bit should raise after all is send out) the uart send´s nothing,
interrupt is never fired and nut run´s endless in eventwait.

any hints ?

best regards
martin
