Hi :
    I install a voice card in PC , when voice input , the ADC will interrupt
8259A , and execute a interrupt handler to read in digital data from ADC .
(hardware interrupt).

    My problem is how can I get the interrupt number ?
    I use TC 2.0 , setvect(intno,int_vect) .
    
    The data inport address is 0x0394 .
    Please help !!!!!
