I'm having problems transmitting ascii characters.
I've tried 2 different microcontrollers (AVR and Blackfin), 3 different types of transceivers (rs232, bluetooth, IR), several baud rates (9600, 19200, 38400), and three different serial receive programs (java, hyperterminal, teraterm).
I don't know why it isn't working, but I suspect it has something to do with Windows XP or perhaps my USB drivers.
I know for sure ascii is being transmitted because all the LED's light up during transmit, and regular char and int values transmit fine - but my PC just refuses to accept ascii!
I also noticed that the cursor in both hyperterminal and teraterm freeze whenever ascii is being received, but not when it isn't.
