stty < /dev/modem blocks???

On my 2.2.12 kernel with some hacks I've added I can't use stty to get
the configuration info for /dev/ttyS0. stty < /dev/ttyS0 (aka
/dev/modem) just hangs. strace stty < /dev/ttyS0 does the same thing.
strace doesn't even show me any output. Ctrl-C kills the stty or strace
but shouldn't stty work on the modem serial device to get the config
info? Is it just the hacks I've added in my kernel perhaps? stty
< /dev/pts/0 works just fine. Ideas?
