[En-Nut-Discussion] Blocking UART calls

[Jens Meyer]

Hi all,

Due to the handling of uart and sockets with file 
descriptors it's easy to write software, that uses 
sockets and alternatively the AVR internal uart.
Unfortunatley it seem's, that _read() calls to uart
channels block the system, is that right ? Is there
a way to avoid this behavior and allow background 
threads to work (i.e. serve the watchdog) ?

Regards

Jens
