u may get some clues
i face no such problem, i am able to get com1 to com4 with no troubles whatsoever
my troubles are that even after getting correct com port number, i am not able to establish comminication for most times
my advise to you would be to get a pc with a built-in serial port., %26amp; not try usb to serial converters

USB to serial RS232.?
%26quot;You must have write privileges in the registry for this device in order to modify the device's advanced settings.%26quot;
You can either try to change the properties within the registry to allow read and write or try changing them from the properties page of the device itself.
Another option would be to manually install and set it up by selecting advanced setup and from there you should be able to change the settings to whatever you need, of course you do also need to make sure that there are no other devices listed as using the com1 port or you will get conflict errors and it will not allow you to change it.
To change com port number in windows xp, go:
start-settings-control panel-system-hardware-device manager-ports.After that find in list of ports your usb to serial port (com n, n%26gt;=5) and right click on it and go to the properties-port settings-advanced. Here you can change a port number.
