hi! I was just wondering if I have to use a UART for a PIC16F84A to be interface to a serial port :roll:
 
does it mean to say that If i'm going to send a total of 10 bits to a pin configured as an output I have to do it one bit at a time and then use a max232 to invert the voltage level of the ouput pin :?:

It's best to use a MAX232, although by inverting the bits you can do without it, but it operates outside RS232 specifications (but usually works fine).

And yes, you send it one bit at a time (which is what serial communications is).
