Ioctl and serial ports

[thawkins]

I would love to see support for ioctl and serial ports, i spend a lot of time building projects for arduimos, and usb-serial is the best way of interfacing.

I can have a go at implementing the basics if you would be amenable to a pull request.

That sounds good. I would love to see what you can come up with.

I suspect its mainly about getting ioctrl to work, the rest is just the
normal unbuffered file i/o using device files (/dev/tty*). Ioctrl is also
only really needed for physical serial devices, setting baudrate,
handshaking etc. Most use now is /dev/ttyXxxxx over usb, which ignores
baudrate and does not really need handshakes.

But a serial device wrapper class would be very useful.

If you want to wrap a couple of C APIs, we can add it to the CSua existing module:

For now the CSua module is only wrapping the "environ" API for the environment variables. And they have recently started adding "environ" directly to Swift, at first only for the FreeBSD port apparently. I have yet to test it whether it's enabled for Glibc as well or not.

Noted, i will check it out, im mainly interested in this because i want to
use swift to write a bunch of utilities to drive my 3d printers. I belive
the issue with importing ioctrl directly is that it has a varadic function
signature in "C" and swift imports dont handle that very well at the
moment, so a simple "c" wrapper is probaly called for.

Note: i also created a simple script to manage building if swift on fedora
which is my prefered linux distro. Its that version of swift i am testing
with.

You will have to bear with me, im still learning swift, i come from a long
time c++ and modern PHP background.
