 3 Syntax as a command:  halt dev1 ...  devn {control_arg}

 6 Function:  provides the reverse function of the ready command.  It
 7 places the device or each of the specified minor devices in the
 8 inactive state.  The driver does not ask the coordinator for any
 9 further requests for a halted device.  However, the coordinator may
10 have already supplied a "pending request" for the halted device.  In
11 this case, any pending request is processed immediately after the
12 device has been halted (except when the command has been issued
13 following a quit signal).
