Hardware and Software Development Tools for the HCS12 - The HCS12/9S12: An Introduction to Software and Hardware Interfacing - page 98

If the D-Bug12 command prompt does not appear on the screen, the most likely three
causes are
1. The demo board is not powered up.
2. The RS232 cable connection is wrong.
3. The baud rate of the terminal program does not match that of the demo board.
Make sure that the demo board has been powered up and also make sure that the RS232
cable is connected to the right connector (if the demo board has two RS232 connectors). If the D-
Bug12 prompt still does not appear, then check the baud rate setting. Select the Terminal menu
and unselected Connected and click on Options. The Options dialog will appear as shown in
Figure 3.8. The settings shown in Figure 3.8 are acceptable. Another option that the user needs
to set is Tools. Click on Tools in the dialog box and make sure that asm12.exe is selected as the
tool for assembling HCS12 programs as shown in Figure 3.9. The user may also want to set the
options in the General category. The settings in the General category are shown in Figure 3.10.
The default settings for the options of the assembler are acceptable.
