It's not likely that Max232 is pumping out +/-7.5V or more without the capacitors, more that your terminal accepts the logic level voltage coming out of your pic controller. The RS232 spec allows … for anything between +3 to +15 and -3 to -15. If the supply line to the Max232 is 5V then simply providing +/-5V for the max232 is acceptable to your terminal. Some equipment (sometimes older …
