In order not to accidentally look up my mini (has happened before), I would like to know for certain which of COM1 and COM2 go to the UART and RS232 respectively.
Does anyone know for sure?
Which COM-port is which?

Hi hanzibal,
COM1 is the TTL-UART port (pins 11/12). COM2 is the RS232 port (pins 1/2).

Ok, thanks. I confused them once, hence lost host PC communication and had to reflash. Now I couldn't remember which one not to use.
