Echo (A)

Echo implements a loop back function to test the integrity of the serial
communication. Any text transmitted by the master is returned.
:
Example
Master: >99ABCDEFG4E[CR]

Bad Command (B)

This command is not recognized by the slave. It will therefore result in a
type 01 failure response.
Master: >99BB4[CR]
Slave: N01[CR]

Acknowledge (C )

Requests a simple acknowledge from the slave. Useful to determine if
there is a device at that node address.
Master: >99CB5[CR]
