USB to Serial cable

So after starting to buy and setup all this Cisco gear, then screwing up and forgetting to set the telnet password, and dragging it across the room to plug it back into the serial port, i decided i needed this.  A stupid USB to DB9 adapter for my Mac.  Yes, i know i could make a long crossover out of ethernet cable, but that isn’t as much fun.  And in typical fashion, drivers for USB to DB9 are not great.  So thankfully i found an article by NERD Logger. Pointing out the easy way to just use the source forge driver and screen to use the adapter in shell.
