This would require extra hardware, because rs485 is fullduplex on all VFDs I've seen so far.
This means that the transmit and reception are done on the same 2 wires. The master has to do the direction change.
So this would require an rs485 fullduplex hardware, the uc300eth does not have that onboard.
