+The Tcl standard channels (\fBstdin\fR, \fBstdout\fR, and \fBstderr\fR)
+can be configured through this command like every other channel opened
+by the Tcl library. Beyond the standard options described above they

+If, for example, a Tcl application is started by the \fBinet\fR
+super-server common on Unix system its Tcl standard channels will be
