You need to get a 25-pin gender changer for the blazer; put a 25-pin female to 9-pin male on the blazer, connect your 9 to 9 cable from that to the pc.

The only cables I have are a parallel db25 with male connectors on each end, and a db9 with female on each end. I am connecting the two via a converter that converts parallel db25 to a male db9. I can't just connect one to ther other, without this connecter I can't do anything. What would I do now since I probably don't have the cable you are refering to?
