Serial communications attempting to open COM10: and higher

[Guest]

I am using C#.NET on a Windows XP SP2 computer and when I open a serial port
COM1: up to and including COM9: I have no problems opening these ports.
However, when I attempt to open COM10: or higher, I receive a 'CreateFile
Failed: 123'. I do have a virtual comm port using a Belkin Bluetooth to
serial that has assigned a comm port number 28 to the device and I cannot
change the port number. Does anybody know why I cannot open COM10: or higer?
I am using OpenNETCF for Compact Framework.
