Hi,
I am currently working to configure a MC7354 modem for use on a debian 8.6 build of linux. I have confirmed the operability of the modem on a windows machince, so the modem and SIM card should work. I am attempting to create a PPP connection through wvdial, and it seems as that portion of the setup is performing well, as I get a connected 100000000 string at the completion of my dial attempt.
However, once the PPP daemon is loaded, it seems to hang after intializing and performing a handshake. The ppp does not ever get assigned an IP address. I have included the output for the most recent wvdail connection below:
