Redirect stdin & stdout to serial port

[D.Pageau]

I have to redirect both stdin & stdout to com1

lrz -X -vv foo.bin > /dev/ttyS0 < /dev/ttyS0
bash: /dev/ttyS0: Permission denied

This is working on *nix but not with Cygwin.  Why ?

any work around ?

CYGWIN_NT-5.0 foo 1.5.20(0.155/4/2) 2006-03-19 16:11 i686 Cygwin
