Pci Multiport Serial Controller Driver Dell
Our Clackamas Oregon model RR club has two Dell Optiplex 755 laptops purchased used from a recycle store. The one that communicates with our layout NCE power module through the serial port has stopped communicating and Windows Vista device manager reports the PCI serial port driver is missing and also the PCI simple communications controller and PCI bus controller drivers. PCI Multiport Serial Controller So i followed the instructions. It finds nothing CANNOT INSTALL THIS HARDWARE The hardware was not installed because the wizard cannot find the necessary software.
Hi all,
Have tried three different brands in two different XP machines, and have
the same problem on all.
Problem is:
PCI cards install fine, and appear to be correct in DevMgr.
Using Hyperterminal, connect from onboard com port (COM1) to PCI serial
card com port (COM3 or COM4) using a crossed serial cable.
Transmit from COM1 to COM3/4 works just fine. Characters received.
Transmit from COM3/4 to COM1, and we get no characters.
Have tried swapping the cable around, and same result.
Have tried installing Win2k, and it works in both directions!!
I'm really stuck on this one. It appears to be caused by WinXP, because:
1. It works under Win2k.
2. All three different brand PCI serial cards have the same problem.
3. Same problem exists on DELL Dimension PC, and Commell PC board.

When you troubleshoot issues with a serial device, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue:
Serial cables
Serial ports
Serial devices
To test your setup components, try the following:
Use the serial cable, serial port, and serial device in another setup to see if the problem is with the components or the setup.
Use a different serial cable, serial port, and serial device in your setup to see if the problem persists. Ideally, you should test a component that you know works in another setup.
When you test your cables, it is recommended that you do the following:
Test each cable individually.
Use short cables when you are testing.
When you test the serial ports and serial device, it is recommended that you do the following:

Press the Windows key + R, type devmgmt.msc, and press Enter to open Device Manager. Check to see if your device is listed under Ports (COM & LPT).
Make sure that the COM port number is the correct number for the serial device and that the software being used to connect the computer to the serial device uses the correct COM port number.
If you do not see the COM port number in Device Manager see this FAQ for PCI/PCIe expansion cards: https://www.startech.com/support/faqs/technical-support?topic=expansion-cards#pci-pcie-cannot-boot-os-or-detect-windows
or this FAQ for USB devices: https://www.startech.com/support/faqs/technical-support?topic=expansion-cards#usb-cannot-detect-windowsIf the device is listed with an error, follow the instructions on the website to reinstall the drivers.
