The code in question is in the Windows-specific driver file (drvAsynSerialPortWin32.c), so it is already Windows-specific.  We are not adding OS-specific code to a generic driver.
Oops — I forgot that windows didn’t use the Posix termios code.
 
I don’t like users having to put 6 backslash characters into the device name, where everywhere else in Windows they just say COM10.
 
I agree with Peter’s suggestion that we don’t need a special case for COM1-COM9. 
 
I propose the following:
 
-          If the device name passed to drvAsynSerialPortConfigure starts with  ‘\’  then assume the user has used a device name, and use it directly.
-          If the device name does not begin with ‘\’ then prepend “\\.\”.
That sounds ideal.
