Is RS-232 / Serial Control Possible With Just GPIO?

Shahin -

Is it possible to use the GPIO for RS-232 / serial control of the projector? I've got a USB FT232 board, but it would be way easier to just let the RPi handle that itself. I ask because my projector doesn't seem to like regular HDMI control

Yes, theoretically it should works. But you needs to change default rpi settings as serial port is used for console.
Use external serial to usb adapter as it does not require any change.
