Resolved: Error - Asynchronously connecting to the modem: connection setup cancelled.

[Nicholas Smith]

Hi Aleksander,

I was unable to detect the modem when starting /usr/sbin/ModemManager —debug.  The original problem I was facing seems to have disappeared.  I am able to connect the modem by issuing -e followed by —simple-connect.


Regards,

Nicholas S.
