I want signal strength information when a pppd connection is already running. I am running pppd on an embedded Linux environment and a 3g modem manufactured by Cinterion.
I know commands from which I am able to know signal strength but when my pppd connection is running it will block /dev/ttyUSB and because of that I am not able to find signal strength information.
