Hi folks,
I am new to the Conduit, but love the concept.
I am trying to get the MTCDT-LVW2 connected to the Verizon network.
I have followed the MultiTech developers manual to install the SIM and enable the cellular radio but I cannot get the PPP connection up.
I SSH’d into the Conduit and checked /var/log/messages and I see the messages below.
Is there a reason that I would get the ‘Serial connection established.’ message and then one (1) second later I get the Hangup (SIGHUP), Modem hangup, and Connection Terminated in quick succession?
Thanks for any leads,
Jim Burns
