I am trying to run internet via HUAWEI E3372 on Debian. It worked on Windows but did not work on Debian.The error is this: ATDT*99# ERROR --> Invalid dial command. wvdial: utils/wvtask.cc:303: static int WvTaskMan::yield(int): Assertion *current_task->stack_magic == WVTASK_MAGIC' failed.

It was empty resolve.conf simlink so I copied /etc/ppp/resolve.conf one and it worked. Anyway **the error still remains** and I would like to get rid of it. Also note that I am doing all with Network Manager service disabled.
