Hi everybody!
I want to use Windbg but I don’t have a serial port on my laptop (my host)
neither on my target computer as required. My laptop only has one DB25
parallel port (it’s a female port). My target has one DB25 female port and two
DB9 male ports.
My question is very simple:
Is it possible to convert a parallel port into a serial port ?
If yes, how to achieve that?
Thanks for considering my question =),

On the develppment system anything that presents a serial port software
interface (i.e. comX) will work. On the target of debugging you must have a
standard serial port, the debugger works directly to the hardware.
Are you sure your target doesn’t have serial ports on the DB9 connectors?

You have several options. Male DB9 connectors are probably serial ports,
so you may actually have them but they may be disabled. I would check
this first. On your host laptop the best recommendation would be to use
a PC-Card serial port.
If these two things are not possible you may then try using firewire, if
it is available. Many laptops have a firewire port, often in the mini
form factor. If the target machine doesn’t have firewire, there are a
lot of inexpensive firewire cards out there. There has been some
discussion of problems with some chipsets, so you should research this
in the list archives.
Finally, with the latest version of the windbg, you may be able to use
USB to connect. There are articles regarding the cable you will need, so
research this carefully on the Microsoft site.
My best results have been with serial, so I would recommend trying to
get that working if at all possible.
I hope this helps.

USB to serial is iffy at best at anything above 9600 bps. At least that has
been my experience the times I have tried it.
The DB9 ports, as stated, are most likely serial. Look in the BIOS and see
if they are enabled. If they are not there, and not simply disabled, my
suggestion would be to change mother boards to one with serial AND 1394. You
can get a serial PCI board for the target, and a Socket serial card will
work for the laptop. Most likely your laptop has 1394, so if that is your
desire, then a target mother board with 1394, or a PCI board using the TI
chipset for 1394 is the recommended way to do 1394.
Do NOT use or get the DLINK DFB-A5 USB/1394 card. DLink will not support the
1394 interface and it simply does not work.

The host can use USB-to-serial.
The target must have the UART hardware (or use 1394).

Hi!
I finally could send messages between my two machines through Hyperterminal by
using an USB-to-serial converter on my laptop as suggested by many reviewers.
It wasn’t obvious to find the right COM ports configuration but I finally could
see the caracters I typed on both machines.
I’d like to thank all of you guys for your “more than expected” number of
replies. I really appreciate that. I hereby enclose the replies I got for
those who will face this problem.

The DLink I have is 3 years old and has the VIA 1394 chipset Tim. I have
never been able to get it to work with the debugger, and for the past week
with a brand spanking new install of XP/SP2 on the target, the 1394
controller has been yellow banged out. DLink does not provide the drivers
for the 1394 side of the board, expecitng that support from the OS, and the
OS drivers don’t drive. Oh well, hopefully my new target will be in this
week and 1394 will finally work.

The device driver on the target should be disabled. The “normal” drivers
need to be disabled – the kernel debugging support built into the NT kernel
has its own, specialized drivers for communicating with the debugger.
Yellow bang is actually GOOD. It means the driver could not start –
presumably because the debugger support already owns the hardware.

Arlie,
It’s been yellow banged since the XP/SP2 install, essentially 1394 in this
system has never worked. Thinking the same thing as you did though, I tried
to connect to the host using the debugger by setting the 1394 information in
the boot.ini files, but no joy. 1394 in this system is jinxed. I think when
I get the new system I may introduce the DLink card to a 16 pound sledge
hammer. At least I can get SOME satisfaction. But, the card belongs to
Seagate and I shan’t do that.
