I have a new Tyan mobo with a 10 pin secondary COM port header. The pinout looks standard - I have the pinout diagram. (but I am no expert on hardware). I can't find a backplate with cable that is 10 pin here in Thailand and can't order one from the Internet. (It's a long story).
I am thinking of just opening up the closed 10 pin location on the female plug on the end of a standard backplate cable and plugging that in, but this is an expensive server mobo - I don't want to take a chance of harming it.
I wonder why some mobo would use a 10 pin when serial is all 9 pin now...
Anyway, what do you guys think - should I give it a go or do you have any other ideas?
