Hey Jan, See comments inline below.

It's ok to reply-all; but we're now talking in an email thread about the ID_MM_TTY_BAUDRATE related patch, which you didn't even test :) The original thread you opened had subject "Could not acquire the 'org.freedesktop.ModemManager1' service name"; and things have evolved from that original issue to the fact that the TTY isn't correctly probed, and now we're talking in the email thread about a patch I sent last week which is already merged in git master; a bit of a mess! ;) BTW, now that we're into mailing list etiquette, top-posting is also not a good way to write to the mailing list, see: http://www.idallen.com/topposting.html These two previous things are so that everything is kept tidy for everyone to easily follow; not everyone is interested in every topic posted here. :) > I have done mmcli -S and that command response with "successfully requested > to scan devices".

Please test "mmcli -S" using ModemManager git master, because a recent patch there allowed to fully re-probe ports that were not acquired by any modem, as in your case. -- Aleksander https://aleksander.es _______________________________________________ ModemManager-devel mailing list ModemManager-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/modemmanager-devel
