After adding the udev rules, mmcli shows ports: 'ttyUSB0 (unknown),
ttyUSB1 (unknown), ttyUSB2 (unknown), cdc-wdm0 (qmi), wwp0s20u4i8
(net)'. Notable is the addition of ttyUSB1.

I didn't even need to issue any AT commands:

# echo \$GPS_START > /dev/ttyUSB1
# gpscat /dev/ttyUSB1

Produces NMEA strings. So I'm off to wire up gpsd, next.
