[En-Nut-Discussion] Re: a yielding I/O flush

[JasonG]

Found it, I'll answer myself:

#include <sys/uart.h>

int UartAvrFlush  (  NUTDEVICE *    dev  )   
 
   Wait for output buffer empty. 


If the output buffer contains any data, the calling thread is suspended
until all data has been transmitted.

Parameters: 
dev  Indicates the UART device. 

Returns: 
0 on success, -1 otherwise.
