Aside from finding the port (which is done for you automagically by
IOKit), this kind of thing is done the same way that you would on any
*nix platform. I recently ported a little tool for my watch from Linux
to Mac OS X, the code of which is at:
http://reading.is-a-geek.com/cgi-bin/cvsweb.cgi/fton/rupserial.c
(was originally written by a Japanese fellow for a Seiko ruputer, then
ported to the American Onhandpc, then I ported it to Mac OS X)
I wouldn't use the same flags that I did, unless you've only got three
pins on your serial port like the device I was using and can't do flow
control, etc.

I need some help finding a starting point to communicate with an RS485
device I am building. It is a modified version of a USB RS232 adapter
so the drivers exist already I just can't wrap my head around opening
the port, setting speed, etc, sending the data and closing the port.
Most of the sample code I have found deals with modems and isn't
commented to the point that I can figure out what parts are modem
specific and what parts aren't. I'm sure there is a book or website
out there somewhere that will provide the hand holding I need I just
can't find it. I have looked through Apple's Serial port sample and
get a little of it but not much. If anyone knows of something like
_Cocoa Programming for Mac OS X_, or _Programming with Objective C_
(as these have been very helpful in other areas) that covers USB,
serial ports, etc I would appreciate it.
Thanks,
Mike
