Unable to access any ports above COM9 in Windows NT with an application.
I'm writing my own application and I am not able to access any ports above COM9.
In Windows NT, the ports above COM9 must be addressed with the following naming convention: .COM#
For example, COM10 should be addressed as .COM10. You may also address COM1-9 with the same naming convention. Windows NT will recognize either name.
