Is it a parallel programmer?  In other words, it is expecting the DB-25 
to be a parallel printer port?  If so, I don't thing there's a solution 
for you.  You'll need a different computer or a different programmer.

Graham.

If you don't want to do the hardwiring yourself (no big deal really) you 
can get a DB-9 to DB-25 serial adaptor.

If you don't mind doing the hardwiring, do a Google search for "DB-9 
DB-25 RS-232" or something similar and you'll find a schematic of the 
wiring pattern. You most likely only need three wires.

   You will need to obtain a parallel <-> USB adapter.   Typically 
available in the US for about $20 retail.

There is no way to connect your parallel port programmer to USB or 
serial.  You'll need another programmer that works on USB or serial.
