Specifications - Software
The TWO female Din8 serial ports on the Keyspan Adapter are seen as serial ports by Mac OS.
The Keyspan serial ports are interfaced via the " CommToolBox " API and are then available to any
program that accesses serial ports via this API. For programs that don't use the CommToolBox to
access serial ports, the Keyspan adapter can emulate the PRINTER and/or MODEM ports as
found on older Macintosh computers.

Note: You can only have one PRINTER port and one MODEM port on
any given computer. In order for the Keyspan adapter to emulate
either of these ports, the MODEM or PRINTER ports must not be 'in
use' or registered by other software or hardware. For example,
PRINTER/MODEM port emulation is not available on a Mac that already
has a MODEM and PRINTER builtin (any pre-USB Mac). MODEM port
emulation is not available on any Mac that has an internal modem as
internal modem typically emulates the MODEM port (PRINTER port
emulation is typicall available on these Macs). Printer/Modem Port
emulation can turned ON by using the
Keyspan Serial Assistant
's
Advanced Setting's screen.
On Mac OS, Port 1 on the Keyspan USB Twin Serial Adapter is named " P#1USA28X yyxx ".
This port is accessible by selecting the " P#1USA28X yyxx " port name or the USA28X icon in
your serial device's software . This port is published via the CommToolBox and can be accessed by
CommToolBox Savvy software.
On Macs that do not have built-in serial ports (ie 'Blue and White' G3s, iMacs, iBooks, G4s, etc...),
Port 1 can emulate the PRINTER port (as found on older Macintosh computers) for serial devices
that are not CommToolBox Savvy and can't access the " P#1USA28x yyxx " port. Printer Port
emulation can turned ON by using the
Keyspan Serial Assistant
's Advanced Setting's screen. Once
you've emulated the Printer port, Port 1 will be accessible by selecting the 'PRINTER' port icon or
'Printer Port USB' port name in your serial device's software. Printer port emulation is turned OFF
by default.
On Mac OS, Port 2 on the Keyspan USB Twin Serial Adapter is named " P#2USA28X yyxx ".
This port is accessible by selecting the " P#2USA28X yyxx " port name or the USA28X icon in
your serial device's software. This port is published via the CommToolBox and can be accessed by
CommToolBox Savvy software.
On Macs that do not have built-in serial ports (ie 'Blue and White' G3s, iMacs, iBooks, G4s, etc...),
Port 2 can emulate the MODEM port (as found on older Macintosh computers) for serial devices
that are not CommToolBox Savvy and can't access the " P#1USA28x yyxx " port. Printer Port
emulation can turned ON by using the
Keyspan Serial Assistant
's Advanced Setting's screen. Once
you've emulated the Printer port, Port 1 will be accessible by selecting the 'PRINTER' port icon or
'Printer Port USB' port name in your serial device's software. Printer port emulation is turned OFF
by default.
Note: If you install more than one Keyspan USB Twin Serial Adapter on
your Mac, Port 1 and Port 2 on subsequent adapters will have different
names (please contact Keyspan for details).

Step 4 - Determine Where To Select/Configure The Keyspan Serial Port(s)
Prior to using your serial device with a Keyspan serial port, you must first tell that serial device's
software which serial port your serial device hardware is connected to.
For example, if you have a Palm, you will have to tell the Palm Desktop software to look for your
Palm handheld ( hardware ) on a Keyspan serial port. By doing this, you establish communication
between your serial device's software (ie the Palm Desktop software) and your serial device
hardware (the Palm handheld unit).
Most serial devices will have software that will allow you to select which serial port the device is
connected to. Depending on your serial device and its software, you may have to configure: a
Control Panel (ie modems accessing ISPs), an application (ie UPSes), or some combination of
these (ie modems accessing terminals using Zterm).
Please refer to your serial devices documentation on which method your serial device uses and how
to access that software's serial port "configuration" screen.
Once you've determined where to select or configure your serial device's software's serial port
settings, please proceed to Step 5.
Step 5 - Determine Which Serial Port To Select In Your Serial Device's Software
When you've found the port selection screen in your serial device's software, you may be presented
with a list of serial port names, a list of icons, or some combination of both.
At this point, you have to select the name or icon of the Keyspan serial adapter you are connecting
to. Please note that you can see the port name and icon port name of your Keyspan Serial Adapter
in the
Capabilities
section in this manual.
Step 6 - Use Your Serial Device
Once you've configured your serial software to use the Keyspan serial port, you're ready to start
using your serial device under Mac OS.
