Query: Mini Null Modem DB9 Male / DB9 Male, Adaptor

BEWARE, MISLEADING!!! This is only a male to male adapter. It is NOT a Null Modem. Only and adapter. I bought this for my HP1 SCANNER and it required a Null modem for Gps hook up. I ended up buying a real Null Modem from Rsdio Shack for 4 bucks and that one works like a charm. The adapter I warn you about is now in the woods behind my house were it will stay till I refind it and pulverise it. This company should be more clear about there crappy useless item.
