If you are using the serial debugger ensure that your own print terminates with println()

Also if using the serial debugger it attempts to determine the connection speed from the code otherwise assumes 115200. If you are using a different speed that 115200 you can override the "Local Speed" on the vMicro>Debugger menu.

The speed of the serial monitor is shown on the status bar of the monitor. depending on screen width the speed will be visible or on the overflow menu

ah sorry i didn't read your report properly. Check the speed on the serial monitor and make sure you have dded a serial.begin(speed) in your code.
