SIO Command $F2 Read Device Slots - FujiNetWIFI/fujinet-firmware GitHub Wiki
This is a command for Device $70 - The FujiNet Device itself (see SIO-Commands-for-Device-ID-$70).
Read Device Slots ($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 |
