PIC16F872-I/SP RS-232 interface

I'm trying to send a program to a PIC16F872-I/SP via RS-232 does anyone have any circuit diagram for the connections for this?

Thanks in advance,

To do that requires a bootloader preloaded in the PIC, so you need a seperate programmer to start with.

Also check the datasheet, and see if the 872 has bootloader capability?, the 876 and 877 do, I'm not sure about the 872 (I've never had occasion to look).

Bootloader is a prety usefull thing. Check my signature for using one... 8)
