ieee488:
If using the FTDI cable on Windows, you'll need to make one configuration change to enable the auto-reset. With the board connected, open the Device Manager (in Control Panels > System > Hardware), and find the USB Serial Port under Ports. Right-click and select properties, then go to Port Settings > Advanced and check Set RTS on Close under Miscellaneous Options.
I am no longer using the FTDI programmers.
I am now trying to use the NEW Arduino USB2SERIAL programmer with the NEW Pro Mini's that I bought.
This is what I am now getting:
