You connect the *cmos-level* input and output pins to the
PIC and the *RS232-level* input and output  pins to the PC.

PIC tx <-> MAX232 cmos-input
PIC rx <-> MAX232 cmos-output
PC tx <-> MAX232 RS232-input
PC rx <-> MAX232 RS232-output

and inverter actualy. A logic level "1" (or 5V), is a RS232
"low" (aprox -5 to -15 V). A logic "low" (or 0V), is a RS232
"high" (aprox 5 to 15 V).

And RS232 levels to CMOS levels also... :-)
