If I remember correctly, the HC11’s bootloader operates at 1200 baud. But this is all handled by Interactive C and its “download firmware” function. You shouldn’t have to separately set serial parameters, unless you’re writing your own bootloader.

If you are writing your own bootloader, I have a simple one written in Java. See http://www.cs.uml.edu/~fredm/courses/91.305-fall02/ and look at Assignments 3 and 4.

It sounds like your USB-serial adapter doesn’t have its driver installed right. Check the System Properties for COM ports; it should show up there. Make sure you have the right driver given the manufacturer of the adapter.

I have the serial interface with a serial to usb connector connecting it to my windows 7 computer. When I open up IC, it just shows the default com port 1 and nothing else. This is not the right port and I cannot connect to my handy board. I installed the VCP driver but still nothing works. Any thoughts?

Thanks in advance for your time.
