Hi Everyone, I am new to ppp, here is what I am trying to do with ppp in linux: - Writing a serial tty driver - this driver shall not handle any real serial port (hardware). - want to divert all the ppp traffic to this driver. Now the issue is, when I tried a simple tty driver with minimal functions, and tried- - pppd /dev/flex_modem(drivername) 115200 i am getting a kernel log Could not attach to channel 0: No such device or address. After primary analysis, I found ppp tries to attach to the tty channed and getting failed. Please help me to solve this probem. Any pointers would be of great help.
