1.1 - Introduction
The Keyspan USB Serial Adapter Software for Mac OS X allows you to add serial ports to your
Mac OS X computer. Using Mac OS X native software, you can use your Keyspan USB to Se-
rial Adapter to communicate with various serial devices via the POSIX API (for more informa-
tion, Serial Ports - Mac OS X vs 'Classic' Mac OS section in this manual) .
Important Note:
The Keyspan USB Serial Adapter Software for Mac OS X will add 'Mac OS X serial ports' to your
computer. These 'Mac OS X serial ports' can only be used by Mac OS X native software (a
program that does not require the Classic environment to run). If you are not certain if your
serial device's software can access Mac OS X serial ports, please read the Serial Ports - Mac OS
X vs 'Classic' Mac OS section in this manual. Examples of serial devices that use Mac OS X serial
ports are modems using PPP (for internet access - configured via the Networking System Pref-
erence icon), Palm Handhelds (using Palm's HotSync Manager), and UPS devices.
