Issue with Linmux multiplex serial driver for EH6ST | Telit Cinterion IoT Developer Community

March 9, 2018 - 11:21am, 4773 views

Hi I compiled and installed the linmux driver as kernel module on an ARM based embedded Linux board.

I connect this board t0 an EH6ST terminal via the RS232 port. I can do a ppp connection and also see the virtual ttyMux devices under /dev but cannot use any of the 3 for AT commands.  Using minicom with the virtual ports give me a no such file or device error.

I expected to see the virtual tty ports with dmesg, but only the base port ttyS0 shows. Is there anything in the actual driver source I need to change to get this to work or any other debugging suggestions.

Thank you
