[Tutor] adding a listbox

[vicki@stanfield.net]

Hi. I am trying to figure out how to use the sio
module. I just need to write to the serial port and
retrieve a response from the same serial port. I know
to use sio, but I am having trouble figuring out just
how sio works. Do I have to use a constructor to open
the serial port? Does anyone have any Python example
code that (very simply) initiates a connection with the
serial port and then sends data to it?

Thanks,
