Read Device Slots ($F2)

Description

Read the current FujiNet device slot configuration. Information for up to 8 device slots is returned at one time, with each device comprising of a 38-byte structure:

00: Host slot (0-7)
01: Mount mode (0 = Read, 1 = Read/Write)
02-37: Display name

The 36-byte Display Name may not be the full name of the file mounted in the slot. Names will automatically be shortened to a length that fits in the buffer.

DAUX1 is used to specify a device slot offset as follows:

$00: Device slots 0-7
$10: Tape slot (in this case, the buffer is only expected to be 36 bytes long)

Parameters

DCB	Value
DDEVIC	$70
DUNIT	$01
DCOMND	$F2
DSTATS	$40
DBUF	Pointer to a 304 byte buffer to hold eight device slots, or a 38 byte buffer when DAUX1 >= $10
DTIMLO	$0F
DBYT	304
DAUX1	Slot offset $00, $10 (see above)
DAUX2	Not Used
