Oops! DOS-ism detected! You *shouldn't* take into account which hardware
you're using. OS/2 does the buffering, and has a big enough buffer to
prevent the UART from overflowing (if you really want to know how big, with
the default drivers it's something like 4 kB). Furthermore people don't
allways have 16450/16550's, but may use completely different serial port
hardware, maybe even using DMA or some other technique.
