Joe, it is called Z38XX and is a windows tool which can be used to monitor the whole Z38 family where its name comes from. I wrote it about a year ago. You can download it free from
http://www.ulrich-bangert.de/html/downloads.html It connects direcly to the Z3805's RS232 connector via a null-modem cable. Murray Greenman, another member of time nuts, has written a nice manual for it (included in the zip) so that you should not have big difficulties to get it run.
