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.
