In fact, once a steady state is reached, when the following are seen in the
mmcli ::

#####################################################
*mmcli -m 0 -e*
successfully enabled the modem

*mmcli -m 0 --set-allowed-modes='2G'*
error: couldn't set current modes: 'GDBus.Error:org.freedesktop.
ModemManager1.Error.Core.Unsupported: Setting allowed modes not supported'

*mmcli -m 0 -r*
error: couldn't reset the modem: 'GDBus.Error:org.freedesktop.
ModemManager1.Error.Core.Unsupported: Cannot reset the modem: operation not
supported'
#####################################################



there is no growth as such in ModemManager logs (being run in debug mode);
only occasional following logs are seen ::


#####################################################
ModemManager[2423]: <debug> [1476696354.255819] [mm-port-serial-at.c:459]
debug_log(): (ttyUSB2): <-- '<CR><LF>+CREG:
2<CR><LF><CR><LF><CR><LF><CR><LF>+CREG: 2<CR><LF><CR><LF><CR><LF>'
#####################################################


What's this mystery???
Is MM experiencing some confusion regarding the /dev/ttyUSB* ports? just a
wild guess :-\
