Hi All,
I have a Windows XP system with two ports of 1394(FirwWire) on it. Can I
transmit the data from one port to other port. The both ports are
connected by a FireWire Cable. What is needed to transmit the data
betweent them.
Any kind of information will helpful.
Thanx in advance,
Kedar
You would like to put a cable between two firewire ports on the same
computer? You can’t do that, firewire does not support loops in the
network. You could have two firewire cards on the same computer and
communicate between the two cards, though. I guess that would work.

If you create a loop between any two ports on the same device then you will
blue screen (at least that is my experience). Loops in 1394 are illegal.
However, you can plug in two host controllers on one machine, run a cable
between ports on each card and communicate between them. I have used that
during development plenty of times.

Hi Bill McKenzie,
Ok if I have two host controllers or two cards with 1394 ports how to
trnamsit way between them is there any application to do it?
Any kind of information is helpful.

Well, on Windows XP, you can use 1394 as network adapters. They will
automatically appear as such. If you connect two computers with a 1394
cable, we will be able to communicate between both using any application
that uses TCP/IP.
Why don’t you tell us exactly what you want to do?

Well, as already stated by someone else here, on XP there is a virtual NIC
created for each host controller, so you can transmit data using that.
Other than that, I created my own driver to send/receive data across the
wire.

Dear Bill McKenZie and Mathieu Routhier,
I want to write an application/driver where I want to trnsmiit data
between two 1394 ports which are physically connected by a firewire
cable(like we use com port for serail communication).
The application can also be used to test the physical connection condition
also. I want this application/driver to work even from DOS also, for this
I think I have to access the OHCI register in PCI configuration space. I
am able to access the register but not able to proceed any further. I have
1394 Open Host Controller Interface Specification document with me.
Any Kind of information will be helpful.
Thanx in advance.
Kedar.

created for each host controller, so you can transmit data using that.Other than that, I created my own driver to send/receive data across the

The DDK has a sample that demonstrates how to use the 1394 bus driver. But, I strongly recommend NOT to use this sample as a starting point for your own driver development. We had that discussion already on this list…
However, for testing purposes the sample may be OK.
You can also take a look at our VHPD1394 Development Kit. It provides everything you need.

Here is what I would do. Get a driver/app combo working between two Windows
platforms as a starting point. Then, from DOS you will have to create a
setup such that the DOS platform looks and feels the same to the other end
of the wire as just another Windows platform. But, you do whatever you want
on the backside on the DOS platform.
Just out of curiosity, why in the world are you having to do this from DOS?

Yes, but BSOD in this case is a 1394 stack bug. It must just cause the
selfID phase failure, which should be handled as enumerating a bus
with zero devices on it.

I agree, it shouldn’t ever BSOD, I was making the observation that it does.
That may have been fixed on XP, I haven’t tried.
