Accessing com ports greater than 9 in TCL on Windows XP

Question

I'm using a TCL script (on Windows XP) to access com ports which selects a port from a serial server. When I access try to access COM10, it doesn't work.

set serialDevice [open COMx r+] 

will open the com ports through 9 but will not work for 2 digit com ports. According to the all documentation I have read,

set serialDevice [open "//./COM10" r+] 

should work as an alternate method and for 2 digit com ports. This does not work for any com ports. Any help?

Hi 5555collier,

This forum is for software developers who are using the Open Protocol Specification documentation to assist them in developing systems, services, and applications that are interoperable with Windows. The Open Protocol Specifications can be found at: http://msdn2.microsoft.com/en-us/library/cc203350.aspx.

I can see that you've posted your question on http://social.msdn.microsoft.com/Forums/en-US/windowsgeneraldevelopmentissues/threads as well and that it has been responded so I think you are in good hands now.

Thanks and regards,
