   The DeskWriter puts up the not responding dialog box when the driver fails
to get a response to a status request.  The most likely reasons for this are
wrong cable, cable not plugged in completely, or bad logic board on the DW.
Since you tried a new DW, I suspect that the cable may be incorrect.  The DW
uses the Standard Apple Peripheral-8 Cable.  This cable switches the transmit
and receive lines in the RS-422 interface.  You may have a cable that does not
switch these lines.  Also, make sure that none of the pins in the cable have
been damaged or pushed back in the connector.  The DW needs both + and - lines
on the transmit side to work.

Hope this helps,
