* FUNCTION: cqd_CmdSelectDevice
*
* PURPOSE: Select the tape drive by making the select line active (low).

* HISTORY:
*		$Log:   J:\se.vcs\driver\q117cd\src\0x11040.c  $
*
*	   Rev 1.6   15 May 1995 10:47:52   GaryKiwi
*	Phoenix merge from CBW95s

*	PHOENIX pass #1
*
*	   Rev 1.6   30 Jan 1995 14:23:32   BOBLEHMA
*	Changed vendors to VENDOR_ARCHIVE_CONNER and VENDOR_MOUNTAIN_SUMMIT.
*
*	   Rev 1.5   08 Dec 1994 11:34:44   BOBLEHMA
*	Added a check for seld to the if statement.  This allows seld selects to send
*	step pulses to the FDC (if a CMS drive is connected).  This changed was added
*	to support the Machete chips set used in Zeos computers.
*
*	   Rev 1.4   11 Jan 1994 14:44:24   KEVINKES
*	Changed kdi_wt004ms to INTERVAL_CMD.
*
*	   Rev 1.3   11 Nov 1993 15:20:54   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 1.2   08 Nov 1993 14:05:54   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 14:39:22   KEVINKES
*	Changed kdi_wt2ticks to kdi_wt004ms.
