What is this port?

[i like xeons]

I have a hp z620 and i need a serial port for a nokia data cable. 

I found a diagram about the motherboard and it says just "serial (optional)" and it seems rs232 headers have 9 pins instead of 15. Anyone knows what this is?

Edit: its a proprietary HP serial header and u need a thingy that adapts it to a serial port [part number PA716A]

Looks like a USB 3 header to me 

Nah, USB3 header is 19 pins.

The header OP shown is 15 pins

It's a HP proprietary RS232 port, you need the Serial option cable to use it, but I cannot find any evidence of that cable ever existing apart from it being mentioned in the service manual on page 110.

maybe you can try making one yourself? as long as theres the pinouts should be possible but time consuming and probably a pain

The easier solution would be to just get a USB to RS232 adapter, since in all my searching around I could not find any pinouts of this connector or even a image of it.

According to the service manual, that should be an RS232 serial port header. (Page 38 of the PDF.) "COM" written next to it is also a giveaway.

If you want to add a serial port, the HP part number I've been able to find for that kit is PA716A.

I did some research and turns out HP sells a adapter thingy that goes in a pcie bracket slot [search hp pa716a]
HP always makes proprietary versions of stuff for no reason so im not suprised

Serial Port... a COM Port it's silkscreened on the motherboard
