Unfortunately its several parts because the "PORT" can be VGA or Serial or Display port or HDMI. I would be most grateful if someone could provide the part number for the serial adapter. I have had similar experiences with USB to serial adapters in the past and I thought I was hedging my bets with this computer as I could always fall back to the native serial port. Unfortunately I cannot connect it to the machine to continue my testing without the aforementioned adapter cable. I have tried a couple different industrial grade USB to serial adapters without success, it does however appear to like(by like I mean QNX boots without error) the native COM1 port on the 3070. QNX is pretty fussy about serial ports from what I have found. I am using VirtualBox to virtualize an old 486 PC running QNX 2.21 which runs an piece of industrial equipment. Why don't I just use a USB to serial adapter? Well that was my original plan. All I need is the cable to go from the motherboard to a DB9.
The serial port is actually present in the system it shows as COM1 (IRQ 0x04, I/O Range 0x3F8-0x3FF) in device manager and there is a place on the case to install the DB9 connector. If you follow the above link see #6 in the picture in the Ports & Slots section near the bottom of the page. Which is odd since the cable is mentioned multiple places on the Dell website and in the service manual. Neither of them seemed to have any idea what I was talking about. I have tried Dell sales support they referred me to technical support.
