friends i dont know whether this topic is suitable in this section but we are in emergency.
we are doing project which involves sending and receiving data via the Standard parallel port(SPP).(we are using nibble(4 bits) mode to receive data).
consider following code
#include<dos.h>
void main()
{
outportb(0x3bc,0xff);//ffh is just a an example
}
we found that this program dosent affect the data port bits(our computer's lpt1 address is 3bch)
ie the byte ffh is not going to the data port
