Description joe wang 2014-08-07 06:55:54 UTC 
My modem use driver option, and it create five interfaces, ttyUSB0,ttyUSB1,ttyUSB2,ttyUSB3,ttyUSB4.
I use ttyUSB3 as AT port, my program open ttyUSB3, but i disconnect my modem, and reconnect it again, it will create five interfaces as ttyUSB0,ttyUSB1,ttyUSB2,ttyUSB4,ttyUSB5.
Now AT port change to ttyUSB4.
