S9F7 responses

An S9F7 response is given when a message in an illegal format is received from the host device.

"Illegal format" here means that there is a problem with the message composition, such as illegal attributes, or insufficient or too many items. If other problems relating to the item contents arise, the response is SSACK = "CE" (communications error).
