STDOUT/STDERR redirection under DCT

System

I am using iwconfig in a DCT inline to retrieve a value from iw.cfg. The inline works when I run in on the command line, but when run through the UI or with iwdctacleval it appears that iwconfig does not return the value. I know there's something lame and broken with redirection of STDOUT and STDERR for ExternalTask processes on Windows, but now I'm thinking this bug affects inlines too. Has anyone seen something like this? Is there a workaround (other than parsing iw.cfg manually)?
