Re: TI-H: QuickCam
Considering the camera was made to do it. It wouldn't work. The PC
version doesn't have pacing. The mac version can adjust to different
speeds based upon the init. string sent by the computer. Serail (Mac/Unix)
quickcams would work better. I'm adding this into my 'thing'. Check www
page in a day maybe two.
