That's because the situation is slightly different for each developer and each product. This level of personalised mini-consulting service is what DTS does for a living.

If you're building a Carbon CFM application I would recommend that you do the following:

1. Build the app Carbon CFM. Load the appropriate plug-in using
CFBundle or CFPlugIn.
2. Build the classic serial plug-in as InterfaceLib CFM.
3. Build the IOKit serial plug-in as Mach-O.

Another option is to build a package-based application with an InterfaceLib-based binary for traditional Mac OS and a Mach-O binary for Mac OS X. This option will be more feasible when CodeWarrior's Mach-O tools come online.

Also, I thought the IOKit was just used to *find* the serial ports, and then
you used the BSD open/read/write/close to actually use the serial port.

You're correct. That part of the Q&A is slightly out of date. I will revise this as soon as I get time [Radar ID 2661427].

What IOKit routines can you use to send/receive data??

For serial there are no obvious routines to do this. Serial currently requires you to use BSD APIs to transfer data.
