As Paul indicated, the faster the serial port, the more potential
interrupts per second may be generated;  if you don't have buffered UARTs,
the situation is even worse.

If your machine is not fast enough, too many interrupts will end up
resulting in dropped characters, CRC mismatches, resends, etc. etc.
