BusNumber (REG_DWORD) Specifies the system-wide bus number for the bus type. The default value of InterruptStatus is 0x00000000. The value cannot be zero if the port is on a multiport device. The value is omitted if the port is a stand-alone port. InterruptStatus (REG_DWORD) Specifies the raw I/O address for the interrupt status register. The default value of DosDevices is a NULL string.

Sounds like the software Came from XP or Earlier. Especially when it does not come from dell. Software support is not provided on this forum. This is the Dell forum not support for some un named software.

Drivers for the com ports are native to windows as far back as windows 2.0 and MSDOS.

When I go to use the ports and my software takes over they work as needed but when the software shuts down it goes back to the 1200 baud. If I do a safe start in Windows this does not happen. These are not the values set in the Device Manager. Something set them all to 1200 baud, 7 bits, and others, the offending one to me is DTS on.

I even loaded driver software with the add on ports. I added two serial ports and they act the same as the onboard one. I think the problems coms from what was using COM 3, I think it was related to Intel AMT. Also in the bios I selected just COM 1, not COM1 and COM 3. In that case should I somehow unload this PCI serial port ability? Does this involve a piece of hardware that was installed in the machine by the previous owners? I have done this. It appears from the video that these missing drivers had something to do with an IT tech being able to take control of this machine and make changes in a large corporate setting such as Kaiser Permanente where I believe the machine originally came from. So if I understand your answer the 'PCI serial port driver' has nothing to do with the actual operation of the serial port on the machine and it's absence would not have caused the serial port to stop communication. Could it be something related to Work Station? Any help would be appreciated. I suspected AMT was the culprit but I think that is removed. If I do a start up in safe mode this doesn't happen. My use needs RTS and DTR off in normal mode. These are different than what is set in Device Manager. Something takes over the serial port on start up and changes the baud rate to 1200 and some other parameters as well. It has a new installation of Windows 7 Pro.
