I use devices from FTDI (www.ftdichip.com). They can be a virtual
serial port or accessed directly via a third party driver for Linux,
which compiles for Mac and is LGPL licensed.
I then have a class wrapper, dealing with the declares for accessing
the driver from RB 2006. The driver can't handle plug/unplug
notification and isn't really fast enough for continuous full speed
(12Mbps) data, but for everything else it works well.
If you'd like a copy of the class / compiled driver, then feel free
to contact me off-list, or the driver source is linked from FTDI's
3rd Party Driver page.

on OSX drivers for their USB-DIO-32, USB-CTR-15, and USB-IIRO-16
products,
but it is not high on their priority list. They have not heard of
REALbasic, so you might put in a plug for a RB plugin, like the
folks at
www.activewireinc.com/ did for OS9. ActiveWire has been promising
an OSX
driver for over 2 years, and I have gotten tired of waiting.
If anyone knows of a similar product already to roll under
REALbasic for
OSX, please let me know.
