Stuff I write on FreeBSD pretty much works on my Mac (the latter has mo 
serial ports, and thus uses a dodgy USB/serial cable with an equally-dodgy 
driver that hangs the system to the point of requiring a *power cycle*).

And vice-versa; I had to learn how to control DTR etc on a genuine
serial port on the FreeBSD box (I am writing a user-level driver for
a serial device).

As for Penguin/OS (and trying to figure out just which header file uses 
which flags, when I'm using low-level Perl I/O), then forget it.

What really blew my gasket is that "stty -f" on *BSD is "stty -F" on 
Penguin/OS, despite them copying every other flag.

I had a look at how they (Linux) wrote stty.c, and nearly threw up.

So, yes, that's pretty much my answer...
