Another level adapting method could be done using a standard RS232 Transceiver
(MAX3237EAI) adding some resistors to adapt the levels on the HC864-AUTO Input lines.
NOTE:
In this case has to be taken in account the length of the lines on the application to avoid
problems in case of High-speed rates on RS232.
