Names for 8192 baud ALDL frame components?

I'm wondering if anyone has seen some original GM documentation that
describes the 8192 baud ALDL frame. I've tentatively labeled the frame
as follows -
1 2 n
+------+------+------+------+------+--/ /--+------+
|MODULE|LENGTH| MODE | MSG. | MSG. | | CRC |
| ID | +$55 | BYTE |BYTE 2|BYTE 3| | BYTE |
+------+------+------+------+------+--/ /--+------+
[ optional content here ... ]
I've seen people use "Module ID", "Message ID", "Frame ID" etc. for the
first byte. If anyone has some specific information on what GM calls each
byte, I'd be most appreciative. Also, if you have GM names for any of the
ALDL data structures, such as the I/O Control Block (IOCB ?):
IOCB dw $0000 ;pointer to next IOCB or NULL (as shown)
db ID_$F4 ;MESSAGE ID
db 0 ;flags for message action
db 1 ;message length
dw ALDLioBuffer ;output buffer address
dw ALDLioBuffer ;input buffer address
dw ActionProc ;code to call for this message
