Subject: [EE:] Good diagram of UART operation needed

I need a clear diagram explaining how a UART works to illustrate a
lecture. Does anyone know where I can get one? I was hoping to find an
animation type of thing which would show the data being sent out, but
that's probably too much to hope for. Any pointers gratefully accepted.

Thanks,

Joe
