I have a dell optiplex 755 with a pci serial port driver insisting there is no driver but I've installed all the software from Dell and went to the driver dnld page and got everything and still it shows up with a question mark on the device manager. Get drivers and downloads for your Dell OptiPlex 755. Download and install the latest drivers, firmware and software. Go to Dell's website, support, drivers, enter Optiplex 755, and you should be at the driver downloads for Windows XP. Under Chipset, download and install Intel AMT HECI and Intel AMT SOL/ LMS. Can anybody direct me to the driver for the PCI Serial Port and PCI Simple Communications Controller for an Optiplex 755. It is NOT a modem as I do not have anything installed. I am pretty sure it is the onboard serial port driver as no serial com port is showing up in device manager and nothing I load will fix it. Oct 04, 2011 Hello, I recently reinstalled the OS on a Dell Optiplex 755 and unfortunately, I don't have the drivers disc for this computer. I was able to install drivers for all of the hardware components except I could not find the drivers for the 'PCI Simple Communications Controller' Could.
Windows xp boot disk iso download. However, this release has been put behind the scenes due to its conventional windows startup and lacking advanced features. XP SP3 operating system is quite easy to handle and friendly in usage. With an improved Microsoft’s console and more secure network access, Windows XP Iso for SP3 is still a preferred choice for XP Geeks.

I have a dell optiplex 755 (tower), it was shipped originally with vista but was recently reinstalled using Windows 7, 64 bit.
THe serial port driver, and something else called 'PCI Simple Communications Controller' (possibly a modem on the motherboard) are listed as 'other devices' in the device manager, with yellow exclamation marks in the icons meaning they have no drivers installed.
Dell does not list any drivers on their usual website where you enter your service tag. I am pretty sure this is a standard Intel Q## chipset. Does anybody know which one exactly, and where I can get the chipset drivers and particularly, the serial port drivers, for 64 bit Windows 7?

Microsoft windows vista home basic. Go to the drivers section on dell's site and enter your service tag:
1) Install the latest chipset drivers from dell's site.2) If that doesn't work, install the latest networking drivers from dell's site.3) If that doesn't work, install the latest video card drivers from dell's site.

Go to Dell's support site and look up 745C drivers under 'Chipset'. Download the last 2 drivers and install them in your Dell driver directory under Intel PCI Driver Management. Use these to update the drivers in the Device Manager and problem fixed!

The answer is the driver: Intel AMT SOL LMS. For the Serial Port Driver. From the driver list select Windows Vista 64 for Windows 7 / Server 2008 64-Bit.
