i jus got this wierd thought. can we control hardware directly thru pc? i went in for some research and learnt a lot. the best method i found out was to use parallel ports. i made an intensive study of parallel ports. i had an extra parallel cable which i used to study. it was easy to open it up.
only pins 2 to 9 are used named as D0-D7. pins frm 14-25 are ground pins. the "hello world" counterpart of lpt1 ports is to use led's soldered to the port and in C we simply use dos.h and outport() function. i am yet to try this as this has the side effect of pc risks.
