Rating: - Keyspan usb-serial adapters superior to others
I bought both the 4 port Keyspan USB-serial adapter and the single adapter after trying IOGEAR versions. I had various software issues with the IOGEAR when switching ports or plugging in different devices, as it would constantly assign a higher port number. I can only think it is a result of its incompatability with Windows XP (in the fine print of the instructions). The Keyspan USB-serial devices have worked extremely well and can easily switch ports.

That has the added advantage that I can share the session. [...]
Rating: - Works fine
I've been using this USB serial interface for a couple of years now. I've used it under Windows XP, Fedora and Ubuntu Linux. The Windows XP drivers are available on Keyspan's website. Fedora and Ubuntu (except version 7.10) include the drivers in the standard distribution.
The serial interfaces are solid, providing good RS-232 drive levels. The interfaces can also handle decent bit rates. I've used it up to 115200 BPS. It's also very convenient the way it is packaged. Especially ... Read More
