* FILE: \SE\DRIVER\DEVICE\JUMBO\SRC\0X11034.C
*
* FUNCTION: cqd_RWNormal
*
* PURPOSE: Process a read/write/verify operation that has returned
* normally from the FDC.
*
* HISTORY:
* $Log: J:\se.vcs\driver\q117cd\src\0x11034.c $
*
* Rev 1.13 04 Feb 1994 14:28:00 KURTGODW
* Changed ifdef dbg to if dbg
*
* Rev 1.12 27 Jan 1994 15:48:58 KEVINKES
* Modified debug code.
*
* Rev 1.11 21 Jan 1994 18:23:00 KEVINKES
* Fixed compiler warnings.
*
* Rev 1.10 18 Jan 1994 16:19:14 KEVINKES
* Updated debug code.
*
* Rev 1.9 14 Jan 1994 16:16:30 CHETDOUG
* Fix call to kdi_CheckXOR
*
* Rev 1.8 12 Jan 1994 17:06:18 KEVINKES
* Added support for reposition counters.
*
* Rev 1.7 11 Jan 1994 15:13:16 KEVINKES
* Cleaned up DBG_ARRAY code.
*
* Rev 1.6 29 Dec 1993 13:48:48 STEPHENU
* cqd_ReadFDC was changed to treat length mismatches as fatal errors. This
* caused the system to immediately exit and skip the recovery code. Changed
* code to filter ERR_INVALID_FDC_STATUS and execute the recovery code.
*
*
* Rev 1.5 02 Dec 1993 14:50:04 KEVINKES
* Modified to update the crc list instead of the bsm.
*
* Rev 1.4 23 Nov 1993 18:44:42 KEVINKES
* Modified CHECKED_DUMP calls for debugging over the serial port.
*
* Rev 1.3 15 Nov 1993 16:01:46 CHETDOUG
* Initial Trakker changes
*
* Rev 1.2 11 Nov 1993 15:20:34 KEVINKES
* Changed calls to cqd_inp and cqd_outp to kdi_ReadPort and kdi_WritePort.
* Modified the parameters to these calls. Changed FDC commands to be
* defines.
*
* Rev 1.1 08 Nov 1993 14:05:06 KEVINKES
* Removed all bit-field structures, removed all enumerated types, changed
* all defines to uppercase, and removed all signed data types wherever
* possible.
*
* Rev 1.0 18 Oct 1993 17:24:50 KEVINKES
* Initial Revision.
