Is process substitution expected to work in 1.7.1?

Here's what I tried:

kilroyd AT MINIME ~
$ uname -a
CYGWIN_NT-5.1 MINIME 1.7.1(0.218/5/3) 2009-12-07 11:48 i686 Cygwin

kilroyd AT MINIME ~
$ echo LOG:bananas | tee file.txt
LOG:bananas

kilroyd AT MINIME ~
$ cat file.txt
LOG:bananas

kilroyd AT MINIME ~
$ echo LOG:bananas | tee >(grep "^LOG:" > file.txt)
LOG:bananas
tee: /dev/fd/63: Bad file descriptor

kilroyd AT MINIME ~
$ cat file.txt

I'm actually trying to do something like:

socat - /dev/ttyS0,raw,echo=0 | tee \
>(grep "^LOG:" --line-buffered | socat - UDP:localhost:1234)

but am getting the same error as the simpler example. And if anyone
knows whether STDIN would make it out of /dev/ttyS0, (or how to get
that) I'd appreciate the hint.



Thanks,

Dave.
