Second solution could be done using a MAXIM transceiver (MAX218)

In this case the compliance with RS232 (+-5V) is possible.

Another level adapting method could be done using a standard RS232 Transceiver (MAX3237EAI) adding some resistors to adapt the levels on the UC864 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.

The RS232 serial port lines are usually connected to a DB9 connector with the following layout:
