Has anybody successfully established a serial connection from Windows to the Neo?
I tried it with the MOD-USB-RS232 card - no success.

Describe what does it mean "no success"? Nothing displayed on the terminal upon power up or what?

Is this with the default firmware that the board arrived?

Are you using the ribbon cable between MOD-USB-RS232 and the Neo6502's UEXT connector? Or jumper wires?

Did you change any jumpers on MOD-USB-RS232 recently or in the past? You should revert any changes. All jumpers should be as per default.

Is the MOD-USB-RS232 properly recognized in your operating system? Maybe try re-installing the drivers, point manually the entry to the mchpcdc.inf file inside this archive:
