Can you write out an example of how you are currently manipulating ttyS0 for writing, and then how you are actually doing the writing?

What errors are you experencing? I'm assuming runtime errors, but I could be wrong.

If you have a test app which is small (no more than 20 lines) and shows the problem you are experencing, post it to the forum. Please use [code][/code] tags to surround your code.

Thanks
