Performs the remote diagnostic function specified by
n.
Eighteen remote diagnostic items are defined: eight printer ID items and ten printer tally
items. A group of four remote diagnostic functions is assigned to each diagnostic item.
Most of the diagnostic items are maintained in non-volatile memory (NVRAM), but some
are maintained in read-only memory (ROM).
The table that follows describes the variables.
The first item group in the table includes an example of data to send and to receive. Data
sent from the host to write to NVRAM must contain all digits required by the remote
diagnostic item. All data must be ASCII. The printer returns all ASCII data. It is preceded
by the parameter
n to identify the diagnostic item and is followed by a Carriage Return
(0D) to signify the end of the data.
