# COMMAND SET SUMMARY
|
||||
The following is a list of the observed SCSI commands:
|
||||
- 03 Request Sense
|
||||
- 08 Read
|
||||
- 09 Retrieve Statistics
|
||||
- 0a Write
|
||||
- 0c Set Interface Mode / Set MAC Address
|
||||
- 0d **Unknown startup command**
|
||||
- 0e Enable/disable Interface
|
||||
|
||||
- 12 Inquiry
|
||||
- C8 **UNKNOWN**
|
||||
- C9 **UNKNOWN**
|
||||
- CA **UNKNOWN**
|
||||
- CB **UNKNOWN**
|
||||
- CC **UNKNOWN**
|
||||
|
||||
A number of other SCSI commands are implemented, but their usage is not yet fully known.
|
||||
|
||||
## Unknown Startup Command (0d)
|
||||
Command: 0d 00 00 00 06 00
|
||||
|
||||
Function: ***Unknown at this time***
|
||||
|
||||
Type: Input (Transitions to DATAOUT)
|
||||
|
||||
Host then sends: `00 09 00 07 FF FF FF 00` (The last 00 might not actually be there?)
|
||||
|
||||
Note: The AppleTalk broadcast address is 09:00:07:ff:ff:ff.
|
||||
|
||||
This is probably configuring the Multicast Address Registers of the [DP83902A Ethernet receiver](./docs/DP83902A.pdf) inside the DaynaPort SCSI Link
|
||||
|
||||
10.9 MULTICAST ADDRESS REGISTERS (MAR0 –MAR7)
|
||||
|
||||
The multicast address registers provide filtering of multicast
|
||||
addresses hashed by the CRC logic. All destination addresses
|
||||
are fed through the CRC logic and as the last bit of the
|
||||
destination address enters the CRC, the 6 most significant bits
|
||||
of the CRC generator are latched. These 6 bits are then decoded
|
||||
by a 1 of 64 decode to index a unique filter bit (FB0 –63) in
|
||||
the multicast address registers. If the filter bit selected is
|
||||
set, the multicast packet is accepted. The system designer
|
||||
would use a program to determine which filter bits to set in
|
||||
the multicast registers. All multicast filter bits that
|
||||
correspond to multicast address accepted by the node are then
|
||||
set to one. To accept all multicast packets all of the
|
||||
registers are set to all ones.
|
||||
|
||||
|
||||
|
||||
## Enable/disable Interface (0e)
|
||||
Command: 0e 00 00 00 00 XX (XX = 80 or 00)
|
||||
|
||||
Function: Enable (80) / disable (00) Ethernet interface
|
||||
|
||||
Type: No data transferred
|
||||
|
||||
Notes: After issuing an Enable, the initiator should avoid sending
|
||||
any subsequent commands to the device for approximately 0.5
|
||||
seconds
|
||||
|
||||
## Inquiry (12)
|
||||
Command: `12 00 00 00 LL 00` (LL is data length)
|
||||
|
||||
Function: Perform a standard SCSI Inquiry command: reference the
|
||||
SCSI spec for further information
