And it is ATD123; not ATD. Strange, no semicolon is needed when using /dev/gsmtty to dial a voice call with my current pile of pending changes, just doing ATD123 dials.. Anyways, looks like qmi_wwan needs to be loaded before qcserial module, otherwise we get nine ttyUSB instances and ModemManager can't find any modems. With qcserial module loaded after qmi_wwan, it still takes a long time for ModemManager to find the modem. Then unrelated to the qcserial module, also looks like I can no longer use the GPS with ModemManager: $ mmcli -m 0 --enable $ mmcli -m 0 --location-enable-gps-raw And then chmod a+r /dev/cdc-wdm0 and pointing gpsd to use /dev/cdc-wdm0 used to work, but now it seems that gpsd can no longer read it. Trying to start gpsd manually produces: # gpsd -b -n -N /dev/cdc-wdm0 gpsd:ERROR: SER: /dev/cdc-wdm0 already opened by another process gpsd:ERROR: initial GPS device /dev/cdc-wdm0 open failed gpsd:ERROR: can't run with neither control socket nor devices open And lsof shows /usr/libexec/qmi-proxy having it open. Anybody know what I might be doing wrong?
