Keyspan Mini Port Replicator
Many modern desktop and laptop PCs no longer offer serial and parallel ports -- yet serial and parallel devices are commonly used in many industries. No ports?... No problem! This mini port replicator combines a USB serial adapter, USB parallel printer adapter and 2-port USB hub into one compact accessory.
I carry one of these in my laptop case to allow me to connect to serial ports on Cisco routers and Sun servers. Don't leave home without one.
The current model, the UPR-112G, has completely new internals. Unfortunately, that means the drivers will not work with the older UPR-112 models, which is what I carry. They are currently available from the old Keyspan site, but it will probably be going away, so I'm capturing them and adding them here... for my own use.
