4.4.2 ERROR MESSAGES
The PPC2+ will always reply to a program message while using the classic format. If the
program message is incorrect or contains invalid data, an error number will be returned in the
form <ERR#n> where n is an integer number that represents a specific error. This allows for
easy error trapping by the host computer.
In the enhanced format, each error is placed into the Error Queue as it occurs. The <ERR?>
query can then be used to remove from the queue and reply the text description of each error
that has occurred. If you are using the COM1 port, the Error Queue is cleared each time a
program message (except <ERR>) is received. Section 4.5 explains the details of the
Error Queue. Table 13 is a list of the possible errors numbers and the error description
for each.
