Flags
The corresponding Explicit Communications Error Flag will be OFF if the
instruction ended normally or ON if an error occurred.
If an error occurred (corresponding flag in A213 ON), the corresponding Com-
munications Port Error Flag can be used to determine whether the explicit
message itself was not sent (corresponding flag in A219 ON) or that the mes-
sage was sent but there was an error in the message (corresponding flag in
A219 OFF).
The corresponding Communications Port Completion Code (A203 to A210)
will be 0000 hex if the instruction ended normally, an explicit message error
code if an explicit messaging error occurred, or a FINS error code if a FINS
error occurred.
For details on the general operation of the explicit message instructions, refer
