What is hh3cRS485RXCharacters?
This counter reports the total number of characters the RS485 port has received from the attached serial device. Comparing this against hh3cRS485TXCharacters lets an admin confirm the serial link is bidirectional and that replies are actually coming back. A value stuck at zero while TX keeps increasing suggests the remote device isn't responding or the receive wiring is faulty.
