Hi all :
It is sorry to bother you. I have some question about this document( PWG
1394 Transport Command Set Proposal Revision 0d). May someone help me.
Thanks.

1.In 3.3 Parameter Encoding,where should these paramemters be placed???
In Status ORB and TRANSPORT_OPEN command ORB, which field should it be
placed??? the reserved field??? the residual field???

2.In 6.1 TRANSPORT_CAPABILITIES command,which field should the initiator
place the parameter id????Or if target receive this ORB, it will response in
the same way... It dose not seem make sense.

3.If there are two device, initiator wants target to the send file
(command 4). The file size is just known by target. How does initiator get
this information(file size)??? Using Status ORB??? and if the initiator just
want target to write the data on the fixed CSR address range( for example.
FFFF F0011000 ~ FFFF F0012000). But file size is larger than this memory
buffer. How should I implement????

Hope these question might be my misunderstanding to the spec. If so,
please correct my opinion. Thanks. May you have a good day.
