Returned Errors
If there is a communication error in the query the 5MC does not reply.
If the network communication is Ok but for some reason the 5MC cannot correctly execute
the query then it will return an error reply. In an error reply the function byte is returned
OR’ed with $80 and the following byte contains the error number. The table below shows the
query/reply that would be expected if the slave was busy
