i would like to thank Scarlet 7,hammer and vvv for the help..they're really helpful.
but i have another problem, the terminal application that i want to build using nic(network interface card) is supposed to be working and sending data in the MAC layer. which means i'm going to create my own packets and send them via the network card to another computer connected to mine via rj45 cable.
can a network card be used for this purpose? if can, how?
can somebody help me please?
