The DJGPP libc might be using BIOS, but the C libs I was talking
about, i.e. the special purpose serial comms libraries, don't --- they
use direct I/O port access to the UARTs.  That's the only way you can
achieve high baudrates, use FIFOs, or do just about anything that
really makes serial ports useful.
