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?
