I’m not convinced that burying windows-specific code like that into the configure command is a good idea.

What’s so hard about just noting in the documentation that COM ports above 9 require special naming — and since the IOC shell treats backslashes separately:
drvAsynSerialPortConfigure(“L10”, “\\\\.\\COM10”, ……..)

That may depend on which version of asyn you are using.  The upcoming R4-27 release contains the following in the release notes:

*******************************************
Fix to automatically prefix COM port names larger than COM9 (e.g. COM10, COM11, etc.) with "\.\". This is needed for all ports except COM1-COM9. Thanks to Freddie      Akeroyd for this fix.
*******************************************

If you are running the master branch from github you already have this fix.  If not then I think you can work around the problem by using the full path name to the port when you open it, i.e. \\.\COM10.
