If you want to mirror the traffic from the ethernet NIC to the serial line, there will be problems: While even the slowest ethernet will receive data at 10MBit/s, serial I/O chips can transmit at 115kBit/s max.(i.e. roughly 0,1MBit/s.) The speed difference makes mirroring ethernet traffic on serial i/o, say, interesting.
