RESET request
Response
An attempt was made to write to a Read-only area.
Access was made to an area not defined on the device.
An access request greater than 1436 bytes was made.
Invalid parameter contents, such as receipt of a non-supported command.
Invalid transmission length, such as an inconsistent data size with the
number of data items calculated from the UDP/IP.
Too many tasks are waiting for ACK data, causing a resource shortfall. The
resources can be released by a timeout.
