Thanks.  It turns out the boss ordered some cables today from American
Video Equipment, before I got to submit my order.  I'll try it his way
first.  What I plan on doing is connecting my laptop right to the cash
register first with a USB to Serial interface and use Hyperterm to
make sure the data is clean.  Then I'll use the laptop at the DVR end
after the connections are done to verify data before hooking up to the
DVR.  I'm new to POS integration so this is gonna be fun.
