Hardware Overrun Error Messages
A common problem with serial communication is ‘hardware overrun’ error

there are other factors and there are simple solutions.
High Baud Rate
Hardware overrun errors and the frequency of this error depend on the PC
configuration, however the baud rate is normally the most critical factor. Generally
the higher the baud rate, the greater the probability of a hardware overrun.
