+<strong>Serial cable connection</a></strong>
+</font></h3>
+All of these machines require a special serial cable which does
+voltage conversion, and can hopefully be purchased along with the
+card.  This cable normally contains a little max232 or similar chip
+which converts from the 3.3V signals to +/-12V.  Or you can attempt
+to build your own using
+<a href="http://www.mizore.jp/wiki/index.php?LANDISK%2Fserial-console">
+some Japanese instructions</a>.
+<p>
+The cable converts from a DB9 connector to a 5-pin header (3.3V Rx Tx GND NC).
+All the boards have a 5-pin connector (called CN7) which the cable can plug
+into; except for the USL-5P which has a 4-pin header and also requires that
+the Rx and Tx pins be swapped.  The IO-DATA cable has pins which can grip the
+inside of the holes.
+<p>
+A USL-5P is shown with a modified little cable.  The DB9 is glued into a slot
+cut into the plastic between the ethernet and a USB port.
