It won't ever work because the shell tries to open /dev/ttyS0 without
O_NONBLOCK being one of the flags, and in this case it will wait for
carrier detect before the open() returns.
A small program to open the device with O_NONBLOCK and set CLOCAL
before passing control to the original command could be useful. I'll
see if I have some spare time to work on it.
You could also open the file with NONBLOCK set in expect (see "man
3tcl open"):
set tty [open /dev/ttyS0 {RDONLY NONBLOCK}]
exec stty 115200 -echoe -echo raw <@ $tty
close $tty
