Chapter 7 Troubleshooting the System 163

I386kd.exe supports the following command-line switches:

-b Causes the debugger to stop execution on the target computer as soon as

possible by causing a debug breakpoint (INT 3).

-m Causes the debugger to monitor modem control lines. The debugger is only

active when the data carrier detect (DCD) modem signal is asserted; otherwise,

the debugger is in terminal mode and all commands are sent to the modem.

This option can be used only with a remote debug configuration.

-r Toggle output register flag.

-v Verbose mode; displays more information about such things as when symbols

are loaded.

-x Causes the debugger to stop execution on the target computer and break to a

command prompt when an exception first occurs rather than letting the

application or module that caused the exception handle it.

Citrix recommends that a batch file be used to configure the environment prior to

executing I386kd.exe. For example, assume the following host configuration:

Remote debug configuration

Host modem is connected to COM2

The baud rate is 9600

The host’s symbol tree is located in C:\Debug\MF18\Symbols

A log file is created in C:\Debug\MF18\Symbols

Here is a sample batch file using the assumptions listed above:

REM Sample Debug Batch File: SETDEBUG.BAT

REM Set Remote Debug Configuration: COM2, 9600 baud

set _NT_DEBUG_PORT=com2

set _NT_DEBUG_BAUD_RATE=9600

REM Set path to debug symbols

set _NT_SYMBOL_PATH=c:\debug\mf18\symbols

REM Enable logging and set log path

set _NT_LOG_FILE_OPEN=c:\debug\mf18\symbols\debug.log

REM Start kernel debugger: Verbose mode, Monitor DCD

i386kd -v -m

Running the Kernel Debugger

The actual debugging process is outside the scope of this document. This section

describes only how to verify that the debugger is installed and configured

properly. Once this is verified, the system is ready for a support engineer to debug

the system.

Local and ICA Debugs

When I386kd is executed on the host computer, the following text is displayed:

1 2 ... 172 173 174 175 176 177 178 179 180 181 182 ... 185 186
