The problem is probably a zombie process that hangs the device.  We have
ESIX rather ISC so the following may or may not work for you.  Touch the
device file (touch /dev/rmt0).  What this does is wake up the zombie so
that it can die.  No guarantees on this, but you might give it a try.
It may take two or three touches to clear the device.
