Test for device in use
« on: March 08, 2015, 03:46:32 pm »
Hi Guys

I need to know exactly what PPPD is up to for a project. I have semaphores working to tell me its up and connected, I have a way to know that PPPD is running however I need to know whats going on at the CHAT stage of things.

I cant see any obvious way to know that CHAT is taking place and PPPD isnt launched so that leaves me with looking at what /dev/ttyx is up to.

Is there any way to know sthat a device is in use, if PPPD isnt up and the port is locked CHAT will be using it or the port is just busy which is good enough for this.
