Three items of UDP information occupying 4 bytes each are returned in the
following sequence. Each value is returned as an 8-digit hexadecimal value.
1. The number of packets discarded because the size of the first short buffer
2. The number of packets discarded due to an incorrect checksum in the UDP
3. The number of packets discarded because the IP overall length in the IP
All the above values are set to 0 if network operation stops due to incorrect
settings in the system setup.
Counting will be stopped when a count reaches the maximum value. The
maximum values are as follows:
Reads the status of the Ethernet Unit’s network memory. The network mem-
