The modem ends up replying NO CARRIER at some point when trying the
connection the first time:

        [mm-at-serial-port.c:298] debug_log(): (ttyS1): <-- '<CR><LF>NO
        CARRIER<CR><LF>'

In the second try the modem didn't return NO CARRIER, connection
succeeded.

Is this something that you can reproduce always? I don't recall having
seen this situation myself when writing the Cinterion plugin.
