Using the Debugger With Microsoft Windows
2-15 Getting Started
2.7 Using the Debugger With Microsoft Windows
When using the debugger under Windows, you must configure a communica-
tion port:
-
Serial Connection: The debugger will communicate with Windows
through Windows com port 1 if you have connected the CDT370 to com
port 1, and Windows com port 2 if you have connected the CDT370 to com
port 2. The standard communication settings (baud rate, data bits, parity,
stop bits, and flow control) are configured directly by the debugger soft-
ware without your intervention and can therefore be ignored.
The advanced settings should be configured by your Windows program to
correspond to your hardware setup. You can verify this by checking the
advanced communications settings of the com port you are using; open
the Control Panel window, select the Ports icon, and compare the
advanced settings for the port you are using (COM1 or COM2) against
your hardware manual.
-
Add-On PC Connection: Regardless of how you set the com port jumper
on the CDT370 board, the debugger software will always communicate
with Windows through Windows com port 3. The standard communication
settings (baud rate, data bits, parity, stop bits, and flow control) are config-
ured directly by the debugger software without your intervention and can
therefore be ignored. You must set the advanced settings, however (base
I/O port address and interrupt request line (IRQ)).
To configure the port, open the Control Panel window and choose the
Ports icon. The Ports dialog box appears, showing icons for the four pos-
sible serial ports. Double-click on the COM3: icon. The Settings dialog box
appears. Choose the Advanced button. The Advanced Settings dialog box
appears. Type the correct value into the Base I/O Port Address; then open
the Interrupt Request Line list and select the proper IRQ number. These
values are determined by the way you have positioned the com port
jumper on the CDT370 board and are shown in Table 2–1 on page 2-5.
Choose the OK button and restart Windows by choosing the Restart Now
button.
