Non-standard baud rates in OS X | IOSSIOSPEED IOCTL

[bruce]

Apple have define an IOCTL (since Tiger) called IOSSIOSPEED which
facilitates non-standard baud rates.

They publish a C example which explains it:

http://developer.apple.com/library/mac/#samplecode/SerialPortSample/Introduction/Intro.html

Attached is a patch for FPC's darwin RTL which adds this IOCTL.

I think it's correct (i.e. it evaluates to the same value, 0x80045402,
as some C I threw together using Apple's headers, see attached).

I've appended this definition in termios.inc as this seems the most
appropriate place for it. Jonas?

Cheers, Bruce.

I can now confirm that the ioctl definition I used is correct, tested on
a Snow Leopard system with an FT232RL chip USB/Serial chip.

Cheers, Bruce.
