Settings for com ports to speed device I/O data transfers

Solution 1:

You can still do that in Windows 10:

  • Run Start > Device Manager

  • Double-click the type of device to configure, for example "Ports (COM & LPT)"

  • Right-click the device to configure and select Properties

  • Select the Resources tab

  • Click to clear "Use automatic settings" (it's unavailable and appears dimmed for devices for which there are no settings to configure or are controlled by Plug and Play)

  • In "Settings based on" select the hardware configuration to modify, for example "Basic configuration 0000"

  • In "Resource settings", select the resource to modify, for example "IRQ"

  • Click "Change Setting"

  • In "Edit Resource" type the new value and then OK

  • Repeat the above for all the resource settings that you want to modify

  • Quit Device Manager and reboot.
