Re: CAN YOU FREE UP COMPORTS 1 AND 3 OR 2 AND 4 FOR USE...
This is done in your BIOS. You need to enter the BIOS at boot time by pressing DEL or F2 or whatever it says during POST but before the operating system starts. Your question reflects a certain level of technical competence so I'll continue, with the advice that you can really mess things up tinkering in the BIOS. On the other hand most BIOSs include a useful "return to defaults" pick for just such occasions.
You need to reserve IRQ 4 for the COM 1/3 pair and/or IRQ 3 for the COM 2/4 pair without knowing which BIOS you have, I can't be more specific how this is accomplished. Your goal is to prevent the PCI bus allocator from stealing those IRQs. Obviously (?) you will need to verify that COM ports are enabled. This all presumes that your special sewing machine application wants to attach the COM port hardware and go around the operating system. At that level you'll need to fool with XP's DOS Compatibility mode settings. Assuming you have XP.
You might try reposting the question naming the operating system and the error or reason why you feel the need to "free up" the COM ports.

The HD3200 on-board (integrated on the motherboard) graphics on this older machine will not support many games. You need to add a separate graphics card to this unit and disable the on-board graphics. Decide on how much you can afford for a new card and check out tomshardware.com VGA charts to see the best performing video card in your price range. You might also consider a newer machine as this is probably about 5 years old. Whatever machine you get, make sure you do not depend on on-board graphics if you want to do gaming.
Hello Manish Poojarv, you can get the code from Sony, assuming you've paid for it. If not, you're out of luck here as we do not provide product IDs or activation codes for anything other than free software - but free software doesn't usually need any code at all..
If your modem is no longer detected you may need to reinstall the driver or in Windows-speek you will have to "Update" your driver.
Right click on "My Computer," go to "Properties," and then to "Device Manager." Here you will see a list of all items connected or supported on the computer. Go to "Modems" find your modem and "Update Driver Software." If you do not see it there either then under "Action" at the top of the Device manager screen go to "Add Legacy Hardware." Follow the prompt and install the modem!
