*
* FUNCTION: cqd_ProcessFRB
*
* PURPOSE: Determine type of I/O operation being requested, Call appropriate
* subroutines.
*
* In block mode operation this routine returns when done processing
* the queue. However, in concurrent operation (task switching or
* non-block mode) the routine NEVER returns. Therefore, it is up
* to ClearIO to stop the task.
*
* HISTORY:
* $Log: J:\se.vcs\driver\q117cd\src\0x11032.c $
*
* Rev 1.20 26 Apr 1995 15:12:46 derekhan
* added vendor
*
* Rev 1.19 26 Apr 1995 12:23:26 derekhan
* merge iomega fix
*
* Rev 1.18 13 Jul 1994 07:27:22 CRAIGOGA
* Added check for CMD_LOCATE_DEVICE if not configured or not selected.
*
* Rev 1.17 03 Jun 1994 15:30:14 BOBLEHMA
* Added a CmdSelectDevice before calling StopTape (practicing safe computing).
*
* Rev 1.16 20 May 1994 10:07:34 BOBLEHMA
* Added a stop tape call for an abort level 0. The stop tape was removed from
* deselect device so now call stop tape before the deselect device function.
*
* Rev 1.15 22 Mar 1994 15:33:34 CHETDOUG
* Format command should not enter format mode
* until after doing the calibrate tape length.
*
* Rev 1.14 22 Mar 1994 15:23:36 KEVINKES
* Modified set mode case statement to not attempt to set
* the mode on a select or a report cfg.
*
* Rev 1.13 01 Feb 1994 12:31:02 KEVINKES
* Modified debug code.
*
* Rev 1.12 27 Jan 1994 15:49:14 KEVINKES
* Modified debug code.
*
* Rev 1.11 20 Jan 1994 09:47:14 KEVINKES
* Added code to reset the FDC if the controller was just claimed
* since we don't know what state it's in.
*
* Rev 1.10 19 Jan 1994 14:05:18 KEVINKES
* Fixed a pointer mismatch.
*
* Rev 1.9 19 Jan 1994 14:02:30 KEVINKES
* Added code to always try to get the FDC.
*
* Rev 1.8 18 Jan 1994 16:19:24 KEVINKES
* Updated debug code.
*
* Rev 1.7 11 Jan 1994 15:16:14 KEVINKES
* Cleaned up the abort handling code to always process the abort even if
* there is no ERR_ABORT returned from DispatchFRB.
*
* Rev 1.6 22 Dec 1993 19:06:40 KEVINKES
* Modified so that a puase tape is issued after a LEVEL_1 Abort.
*
* Rev 1.5 15 Dec 1993 11:37:42 KEVINKES
* Added code to check for a persistent new tape status and return a
* new tape error.
*
* Rev 1.4 23 Nov 1993 18:46:52 KEVINKES
* Removed initialization for the kdi_context.
*
* Rev 1.3 15 Nov 1993 16:20:22 KEVINKES
* Added abort handling.
*
* Rev 1.2 25 Oct 1993 14:30:26 KEVINKES
* Modified so that the check for device selected only occurs if
* the device is configured.
*
* Rev 1.1 19 Oct 1993 15:12:56 KEVINKES
* Chenged DEVICE_NOT_SELECTED error test to check for
* CMD_SELECT_DEVICE AND CMD_REPORT_DEVICE_CFG.
*
* Rev 1.0 18 Oct 1993 17:24:36 KEVINKES
* Initial Revision.
