Is it at all possible for me to manually send and recieve data via an ethernet cable?
Thus for a 10 Mbps Ethernet LAN, the preamble sequence encodes to a 5 MHz square wave!
For a 10 Mbps LAN, the signal spectrum lies between the 5 and 20 MHz.
What about via serial using SLIP? Would that be any easier?
Using 0.8 machine instructions, develop a routine to process and store an incoming Ethernet frame.
