For network relay errors using SEND(090) or RECV(098), check the path of
the command using the routing tables and the nature of the error using the
response code to eliminate the cause of the error.
For network relay errors using CMND(490), the location of the relay error is
recorded in the second through third words of the response, as shown below.
The response codes stored in the Results Storage Area can be used to trou-
bleshoot socket service problems. Refer to Socket Services Parameter Area 1
to 8 (Ethernet Unit to CPU Unit) on page 88 for the location of the response
codes stored in the Results Storage Area.
The UNIX socket service error messages corresponding to the response
codes are given in the following table. Refer to the documentation for the
devices involved when communicating between an Ethernet Unit and other
devices.
