Compatibility: 3.1+

Expects: AX    4409H

BL    drive number (0=default, 1=A, 2=B, etc.)

Returns: AX    error code  if CF is set to CY

DX    Bit 12 is 1: Drive is remote  (if no error)

Bit 12 is 0: Drive is local and DX=IoctlDriveInfoRec

Info: Obtains information about a drive, including whether or not it is

remote (on the network).  For local drives, this returns

additional information including, which IOCTL fns it supports,

and whether the drive is a logical drive created by the Subst

command.

On return, DX bit 12 (DX & 1000H) is 1 if the drive is remote

(i.e., on a network server) and all other bits are 0.

See IoctlDriveInfoRec for a layout of the flags returned in DX

when bit 12 is 0 (i.e., not a remote drive).

Notes:   This is the only way to see if a logical drive ID represents a

Subst drive.  It also lets you see if a local drive is shared

by others on the network.
