I've noticed that, every once in a while, MacNifty sound
digitizers and MacVision video digitizers freeze-up.
It seems to be a screw-up in the handshaking between the
various boxes and the SCC running the serial port.

In the case of the MacVision, it will either flag a "no signal"
error or it will sit around sweeping (vertically) only one of
the collumns of video input.  Since neither of these units
have an equivalent to a "hardware reset" button, I am usually
forced to power down everything in order to get it working again.

On the other hand, maybe my SCC isn't working quite right?

Any suggestions?
