Salut

Am o problema la activarea THREI. Dupa ce scriu datele in bufferul kernel  
incerc sa activez THREI, dar nu-mi intra in intrerupere. Codul arata ca  
mai jos:
i = write_fifo(&data->write, user_buffer, size);
ENABLE_TRANSMIT(data->base);
return i;

Iar ENABLE_TRANSMIT
#define ENABLE_TRANSMIT(x) { char c = inb(IER(x)); c |= 0x02; outb(c,  
IER(x)); }

Problema este ca se blocheaza la testul 0064.
