How do you delete com ports in XP?



Need some help in deleting com ports in XP. To make a long story short we are using a plotting program that reads data from a GPS through a 9 pin serial plug.
We are using a Belkin serial to USB adapter on a Toshiba laptop with XP Pro. We load the driver in for the Belkin adapter and get it to work once. If we stop the plotting program and restart we lose the com port data and have to reload the driver. Xp assign's a new com port each time we reload the driver. We now have com's 1,3,4,5,6,7 assigned to what ever that is not in use.
How do I remove these com ports so I can reuse them? I need com's 1 & 2.

They do not show up in Device Manager. Only the one that is currently in use.

There are no services assigned to these com ports that I can find to shut off.
All I need is a way to remove the com ports. Any ideas?

XP has a habit of doing that. on win 98 you could boot into safe mode and they would all show up in there. XP dont seem to do that. if there is a fault with the driver, they may all still show up as active. try safe mode but i dint think it will work.


Thanks for the reply's but it didn't work. There must be a way to delete the com ports of you are going to run out of them. We are going to use system restore to see if that works. :(
I'll let you know


Tried Restore but it didn't work. When I get to work tomorrow I'll try the hidden devices. Thanks for the help so far. Any other ideas?


You might check in the bios, serial ports may have different settings. Generally you have two serial ports and you can choose the address for it 2f8... or whatever, I think you have four choices or automatic or disable. You might mess around with these settings if it's on automatic try setting it to a static address or maybe even disable altogether if you're using a USB from serial connector.
