Kernel debug problem

Hi,

I have WinDbg 6.1.0017.2

I want to use an industrial PC card for target computer with WinXP. I have
made the serial port connection, and I have tested it with Hyperterminal
(baudrate=115200). It works well.

I have set the Boot.ini on the target( … /fastdetect /debug
/debugport=COM1 /baudrate=115200).
I have set the host (symbol path is
SRV*c:\websymbols*http://msdl.microsoft.com/download/symbols, baudrate
115200, COM1). I start Windbg on the host, then I switch on the target:

Opened \.\COM1

Waiting to reconnect…

and then nothing happened on the host.
The target boots up. If I press Ctrl-Break on the host I get

Connected to Windows 2000 2195 x86 compatible target, ptr64 FALSE

Kernel Debugger connection established.

Symbol search path is:
SRV*c:\websymbols*http://msdl.microsoft.com/download/symbols;E:\NctFewKb\objchk\i386\nctfewkb.pdb

Executable search path is:

Sometimes I get more. Sometimes I get some DbgPrint message, but after
that the target stops and I can not restart it with F5. I try CTRL+ALT+R
too.

What is wrong?

Until the last week everithing worked with the same hardware and software
and with the same settings.
I can debug the computers of my collegues as target with the same settings
and everything is good.

I don’t understand. Please help!

Thanks,
Ferenc

WinDbg 6.1.17.x is broken. Just keep hitting the Ctrl-Break’s & Alt-Ctrl-R’s
