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. -- Hans-Bernhard Broeker (broeker AT physik DOT rwth-aachen DOT de) Even if all the snow were burnt, ashes would remain.
