Sounds like a bug in ucom.  It's also missing the init and lock
devices.  You might be able to get away with simply removing the
UCOM_CALLOUT_MASK from the make_dev() call on line 186 of ucom.c.  That
looks like it will convert ucomX to a callin device.

A correct fix would probably be to copy all the code in dev/sio/sio.c
related to the "devs" array to ucom.c, and name the devices "ttyuX" and
"cuauX" instead of "ucomX".
