Therefore, my solution looks like following: Don't need to check the stdout? IIRC inetd redirects both.
Paulex, I don't thin it's necessary. Even if stdout/stderr are not redirected, RI still returns inherited channel as long as stdin is redirected on Linux.

Any chance to get non-null value if inetd is dummied on Windows? Seems some Services for UNIX(SFU) is provided by MS with Windows server 2003, which can mimic the inetd behavior[1]. I'm not sure if it applies to WinXP, too.
