2.1 - Serial Ports - Mac OS X vs 'classic' Mac OS
This section is intended to briefly explain how 'older' Mac OS (Mac OSes released before Mac OS
X. ie Mac OS 8.1 through 9.x) serial ports differ from serial ports on Mac OS X. This section is
intended as an overview to help you decide whether or not you need to install Keyspan's USB
Serial Adapter software for Mac OS X.
Please note that when 'older Mac OSes' is used in lowercase, we are referring to an operating system or application
software that was made prior to Mac OS X.
When 'CLASSIC' is used in UPPERCASE, we are referring to Apple's CLASSIC
environment that allows certain older (or 'classic') software to run under Mac OS X.
Which Keyspan Software Should I Use?
There are basically 2 requirements in order for your serial device to work natively on Mac OS X:
1. a Mac OS X serial port
(provided by Keyspan's software and hardware )
2. a serial device that has Mac OS X software
(that can see/access Mac OS X serial ports e.g. modem)
Note: We will be posting a list of Mac OS X compatible serial devices soon. The URL
for this page is <http://www.keyspan.com/support/macosx/>.
Since some serial devices are not Mac OS X compatible, you may find cases where it is
better to
not install
the USB Serial Adapter software for Mac OS X and install the USB Serial Adapter
software for Mac OS 8.6-9.x
instead
.
For this reason, we ask you read this guide to help you in determining whether or not you need to
install the USB Serial Adapter software for Mac OS X.
If your serial device's software requires the 'Classic' environment to run under Mac OS X,
please skip ahead to
'classic' Mac OS Serial Ports & Serial Devices
...
If your serial device's software is Mac OS X native software, please skip ahead to

Mac OS X Serial Ports & Serial Devices

If you are not sure if your serial device has Mac OS X native software, please read the rest
