Error Response

If an SSPA cannot execute a Command or detects a protocol violation, an error response
is generated. An error is flagged by changing the "/" command designator in the response
to a "?". Following the "?" error symbol are two characters which are unique error
symbols useful for computer analysis. The two error symbols are followed by a text
string explaining the error for the convenience of a human operator. For this document
ER is used for the generic case examples response.
