DOS Fn 5f04H: Delete Network Connection

                                                         Compatibility: 3.1+ 
 Expects: AX    5f04H
          DS:SI addr of ASCIIZ device name to disconnect
 Returns: AX    error code if CF is set to CY
    Info: Deletes the connection between a local drive ID or device name
          and the network.  The specified device reverts to its original
          (local) meaning.

          The string at DS:SI can be one of:

          ■ The drive letter of a redirected drive, followed by a colon
            (e.g., "D:",0).  This discontinues local access to that network
            drive and the drive ID reverts to it local meaning.

          ■ The name of a printer (e.g., "LPT1",0).  This discontinues
            local access to that network printer and that device name
            reverts to its local meaning as a physical device.

          ■ A string starting with 2 backslashes (e.g.,
            "\\SERVER\FILES",0).  This would be used when a null drive ID
            was used when the connection was made (see fn 5f03H).

   Notes: ■ Network redirection is normally handled by system-level
            utilities rather than application programs.
