Reduces ClutterJun 20, 2008
I have used Keyspans individual port adapters for several years. They work flawlessly and are quite fast. I do a lot of work on high speed serial devices running without flow control. The devices keep up.
I found that I often had 4 single Keyspans cluttering my desk. I wanted this device. When I finally found it, it was a no-brainer. It works flawlessly. (I had hoped it would be less expensive than 4 singles - and it is - just a little.)
A nice little benefit is I use their static mapping tool to make the ports appear as COM11 thru COM14, eliminating past confusion about which port goes with which device.
Serial is officially a legacy device. New PCs don't have serial ports. But, if you have a lot of serial devices to manage, this is a great way to simplify cabling and management hassles.
Keyspan adapters are coolJun 17, 2008
I have used both the dual port and 4 port Keyspan adapters in a Mac OS X environment. Not much to say. They just work. Driver install is simple and creates appropriate /dev/tty... serial ports to access them. I've used CKermit in a terminal window to access the serial ports, and I've used screen (which comes pre-installed in Mac OS X) in a terminal window to access the serial ports. That has the added advantage that I can share the session. [...]
Works fineJun 09, 2008
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 in embedded systems programming, it's nice to have four serial ports right on your desk top with just the one USB cable running to the computer.
