Kevin,

You said, "I did find out that it needs to be sent in ascii but the values have to be sent in the equivalent ascii characters."  I think you may need a little more clarity on this issue.

Actually, it doesn't "need" to be sent in ASCII.  The fact that you're sending the ASCII equivalent values means you're sending raw binary but using the mechanism of ASCII equivalent characters to send them via a terminal program.  If you wrote your own program on the PC to talk to the PWM board, you'd just be sending binary values.  You wouldn't bother doing some conversion from binary to ASCII as you could just send binary.  

The only reason ASCII enters the equation is that you're using a terminal emulator and not a custom program.  As I mentioned in the previous post, terminal emulators typically stink at sending binary data.  RealTerm is the only one I have seen that is any good at sending binary at all, although I'm sure there are others.

Good luck with the project.

Thanks,
PeterM
