i don't have one of those. Is there any type of "software serial" I can use on a GPIO pin?

If I want to connect to a device with a simple serial protocol (9600 8N1), how can I do that when it is plugged into the Expansion Dock? (It seems like the RX line is being controlled by the USB to serial from the dock.)

Ideas appreciated!!

I have a usb camera streaming with mjpg_streamer. How can I get a snapshot file saved that is less bizarre than how I am doing it now.

How I am doing it now:
mjpg_streamer -b -i "input_uvc.so -d /dev/video0"

and then every time I want a snapshot I do:
wget -O /tmp/capture.jpg http://127.0.0.1:8080/?action=snapshot

This works but it offends my sensibilities. Isn't there a cleaner way to do this?

Thanks in advance,
