Subject: Sierra Data Sciences

I recently acquired a Sierra Data Sciences SBC and system and have a 
teeny tiny problem.  There are two serial ports on teh board, clearly 
marked as to which is a terminal port and which is the printer port. 
The problem is that there is a largish number of jumper points directly
below the header on the board, which I must assume are there to configure
the port characteristics.  I have no idea what the jumpers ought to look 
like, and my clone won't talk to it, or vice versa.  The monitor listing
implies I don't even need a disk to get the board talking, the jumpers
may have been set for some really bizaare terminal.  My clone only requires
a three-wire with 6-8-20 jumpered to make my modem do its magic.  

Dies ANYONE out there have a jumper layout for this beast?  The PC traces
to the jumper block are not at all obvious, and my familiarity with a
Z-80 DUART is academic at best.

Thank much in advance.

Marc
