Boot into Mac OS 9.x and use your serial device from there.
Keyspan, Mac OS X Serial Ports & Serial Devices
Serial devices that run natively on Mac OS X access serial ports via the following software:
System Preferences
Mac OS X applications
terminal applications
Regardless of which method is used, your serial device communicates with a software library
called
POSIX
(aka POSIX API).
When a Keyspan adapter is connected, the Keyspan USB Serial Adapter software for Mac OS X
registers a port with the
IORegistry
(this is another software library). At this point, a program
can get the list of available serial ports (including Keyspan serial ports) from
IORegistry
. Once
the program has the list available serial ports, the program uses the
POSIX API
to communicate
with the serial port.
Note: If you are a developer and need more information about using Mac OS X serial
ports, please visit our Developer web page at:

Using the Keyspan Serial Assistant application, you see which
Keyspan
serial ports have been
added to Mac OS X. This is useful in determining which port to select in your serial device's
software. Please read the Keyspan Serial Assistant section later in this manual for details about
the Keyspan Serial Assistant.
Please note, the POSIX API is unique to Mac OS X and cannot be used by applications running
under the
Classic
environment.
