Can't get COM2 to work on 845G MAX

Question

I'm running the 845G MAX with a 2.26 P4 and 512mb RAM on WinXP Pro.
I am unable for get any I/O through COM2.  To test the ports, I'm using HyperTerminal over a null modem cable to a laptop.  When running this config, I have no problem communicating over COM1.  However, when I switch to COM2, I get nothing.  Strangely, the software recognizes COM2 as being there and active, but I can't get it to communicate.
I am using a connector that terminates to a DB-9 male and fits perfectly in the COM2 port on the motherboard.  In the BIOS, I tried setting the Super I/O setting for Serial Port B to both auto and also forcing COM2.  Nothing.
And the strange part to me is that any software I run seems to recognize COM2 as being active, it just cannot communcate over it.
Any ideas?

Try swapping the pins in the cable (ie. 1 with 2, 3 with 4, 5 with 6, etc).  Also, the pinout in the manual is wrong:
Wrong:1 2
            3 4
            5 6
            7 8
            9
Right:  1 6
           2 7
           3 8
           4 9
           5
Worked for me!
Good luck.
