[urq] Somewhat NAC, but relevant - where to get a wireless serial cable - huh?

[Bob]

I do this all the time with mine. Check out the iogear serial adapter

http://www.iogear.com/main.php?loc=product&Item=GBS301

I use it for configuring cisco gear as well, it just works great. You 
need bluetooth on your laptop but if you dont have it, small usb 
adapters are about $6-10 on ebay all day long.
