I think it might be a good idea to write a generic call-in, call-out layer
(maybe merge it into the tty system?) so that every serial port device
could have this feature with little or no modifications.  Admittedly, it
would be a lot harder than just modifying the zs driver, but it would be
a lot cooler :-)
