[ltp] Thinkpad T41 + minicom + Cisco Router

[Dillon Lawson]

I use a keyspan 19 based usb adapter on my t40 and t43.  You have to 
mknod the dev entry then everything is happy.  I dont use Cisco products 
but most routers / switches i configure use 9600 8n1 with hardware and 
software flow control off.

I hope this helps,
