* FUNCTION: cqd_CmdUnloadTape
|
||
*
|
||
* PURPOSE: Position the tape to the physical BOT and track 0.
|
||
*
|
||
* HISTORY:
|
||
* $Log: J:\se.vcs\driver\q117cd\src\0x1100d.c $
|
||
*
|
||
* Rev 1.9 04 Oct 1995 10:58:22 boblehma
|
||
* IOMega 3010 bug fix code merge
|
||
*
|
||
* Rev 1.10 27 Jun 1995 12:33:42 BOBLEHMA
|
||
* Removed call to vqd_PrepareIomega3010PhysRev. Firmware bug is now fixed
|
||
* by called stop tape instead of pause tape in the cqd_ProcessFRB function.
|
||
*
|
||
* Rev 1.9 30 Jan 1995 14:23:58 BOBLEHMA
|
||
* Changed device_descriptor.version to cqd_context->firmware_version.
|
||
*
|
||
* Rev 1.8 27 Jan 1995 13:22:16 BOBLEHMA
|
||
* Added a call to cqd_PrepareIomega3010PhysRev before the call to
|
||
* the firmware function Physical reverse. Note that this function
|
||
* is a NOP if the drive is not an Iomega 3010.
|
||
*
|
||
* Rev 1.7 10 May 1994 11:39:34 KEVINKES
|
||
* Removed the eject_pending code.
|
||
*
|
||
* Rev 1.6 17 Feb 1994 11:38:40 KEVINKES
|
||
* Added an extra parameter to WaitCC.
|
||
*
|
||
* Rev 1.5 12 Jan 1994 15:34:54 KEVINKES
|
||
* Added a line to set no_pause to TRUE.
|
||
*
|
||

|
||
* Cleaned up defines and added an eject pending flag.
|
||
*
|
||
* Rev 1.3 20 Dec 1993 14:49:20 KEVINKES
|
||
* Cleaned up and commented code.
|
||
*
|
||
* Rev 1.2 08 Nov 1993 14:01:56 KEVINKES
|
||
* Removed all bit-field structures, removed all enumerated types, changed
|
||
* all defines to uppercase, and removed all signed data types wherever
|
||
* possible.
|
||
*
|
||
* Rev 1.1 25 Oct 1993 14:35:32 KEVINKES
|
||
* Changed kdi_wt2ticks to kdi_wt004ms.
