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
