I am currently working on Nibble mode of parallel port and we successfully transferred bytes of information from one PC to another using delay method but, facing problems in handshaking(unable to change control bits )….i want some information about handshaking techniques….HELP ME.
what i mean to say is…. if i change handshaking pin from peripheral it changed and according to condition host performs action but when host changes it again it appears unchanged at peripheral….what to do???
