In the files extracted from the RPI Installer, I had to edit
cmdline.txt and change this line:
console=ttyAMA0,115200 kgdboc=ttyAMA0,115200 console=tty1
console=ttyAMA0,115200 kgdboc=ttyAMA0,115200 console=ttyAMA0,115200
After making that change, I could boot up my Pi and the console was showing in the putty session, allowing me to install Raspian.
NOTE: To connect from windows:
- open device manager and find the COM port for the prolific USB-to-Serial Comm Port (e.g. COM14).
- open putty
- select serial as the Connection Type
- enter the comm port from windows device manager (e.g. COM14) in the Serial Line field
- set Speed to 115200.
- If you see a blank screen in Putty, press enter and you should see the setup screen.
