If you've eliminated software problems, perhaps you should be looking more carefully at your hardware/connection. I don't think your problem is solvable with the limited information furnished in the question.
Three USARTs are certainly workable on the 103. Check that you have the clocks enabled. Check that you have the USART, and Rx/Tx Enabled. If you have a Tx interrupt enabled, you'd better have some data to send. Check that you have the correct pins, mappings and settings. If you are remapping, make sure AFIO is clocking.
