Many (as in a TON) of routers still come with serial ports, not to mention 
a ton of other devices that use them. USB ports on a router are kind of 
silly, unless they are meant as host ports for storage or firmware 
updates. They aren't going to work very well for console purposes given 
how little other infrastructure is setup to support them. That and the 
fact that USB is much more complex and flakey than some old 16550 UART 
based serial (albiet much faster). Speed and being "new" isn't always what 
a person wants. Sometimes, reliabliity, being well understood, and 
simplicity trump speed.

Anytime you mention serial, some folks without much experience in the 
fields where they are common act like you are insane for asking about it, 
and give you some shocked "That's OLD!!!" attitude.  Don't listen to them. 
Serial is still very useful and very common. It's just that a lot of 
people don't get enough exposure to those devices.

What I do with Minicom is to create a group that can share the permissions 
of the serial devices you manage. Then you can strip off the SETUID bit 
from minicom and just run it normally. Put it in your rc.local or 
something.
