I just tried to send my first fax.  After I hit enter, sendfax is reporting 
that ttyS3 is locked... locked... locked... give up!  cannot access fax 
device ( locked?)

How is it locked.  I had minicom running then shut it down doing the alt-a 
z x.  Minicom reported that it reinitialized the modem.  If I start minicom 
up again it runs fine on the same device.

Where might I find this lock.
