Redirect output from "start"-ed console

Jun

I have a test.bat which contains just this: "echo blah". When I run
Code:
test.bat > output.txt
I get output.txt containting "blah". How do I redirect the output if test.bat is launched with "start":
Code:
start "test" test.bat > output.txt
I get no output.txt. I tried escaping the ">" with "^" and "\", but no dice.

This works:
start "title" /pgm "%_cmdspec" /c test > output.txt

Note the use of /pgm to force the quoted argument to be considered as the program to be executed; /c to make the session terminate upon command completion. The START command considers the first string following /PGM to be the file specification of the program to be executed, and everything thereafter as parameters to be passed to the program to be executed.

It works for me, although I'm not sure why:
