It seems that the MCU transmits something to your PC since you see a junk at least.
I'd suspect the baudrate is differnet on MCU or PC side. I'd suggest you to double check RS232 communication settings on PC and MCU side (e.g Baudrate, parity, stop bits...). They must match otherwise received data are not interpreted correctly. Particular bean settings depend on the oscillator you are using (external vs. internal).
