+ Sends an FSI BREAK command on a master's communication
+ link to any connnected slaves. A BREAK resets connected
+ device's logic and preps it to receive further commands
+ from the master.

+Contact: cbostic@linux.vnet.ibm.com
+Description:
+ Sends an FSI terminate command from the master to its
+ connected slave. A terminate resets the slave's state machines
+ that control access to the internally connected engines. In
+ addition the slave freezes its internal error register for
+ debugging purposes. This command is also needed to abort any
+ ongoing operation in case of an expired 'Master Time Out'
+ timer.
