Tcl unable to open serial port com22

When I try to open COM22 which is serial port over USB, Tcl answers me the following: 

couldn't open "com22": no such file or directory

Another program opens that serial port successfully.
What could be a reason for that?
Tcl 8.5, Windows 7

These high-numbered ports don't have equivalent DOS names. Use \\.\COM22 instead.
