This function informs Smart Card reader to supply power to VCC pin on Smart card and it also 

needs to send pointer of ATR (Answer to reset) structure to get its status 

 

Entry Parameter 

INT 06H 

AH  =    1 

POWER ON Smart Card 

            ES:DI=   

Buffer of ATR structure 

 

 

Output Value 

AH  =  0    Successfully power-on 

                   

 

If AH=0 CX = ATR length 

1    Time-out ( 1 Sec ,RETRY=1 ) 

2    No card present 

4    Data pin not stable 

5
