the COMMREQ function and then check for a non-zero value indicating that the
Ethernet Interface is responding to the COMMREQ. A good way to do this is to use
a MOVE WORD function block to zero the CRS word.

A status code of 1 in the low byte and 0 in the high byte indicates that the request
was successful. All other non-zero values indicate errors. Refer to the tables below
for a complete listing of major and minor error codes.

The following tables list the error codes that are reported in the COMMREQ Status word
after the execution of a COMMREQ function. These codes also may appear in Word 1 of
the Detailed Channel Status words.
