uBlox has a utility called u-center
<https://www.u-blox.com/en/product/u-center-windows> that's a free
download. You can use it to configure the various output options (and
enable and disable different messages) and a then save this config back to
the module as the start up default.
Downloaded it, hooked up the modules, found that they won't quite get a
fix indoors next to the window, but if I take it outside, it will.
Oddly, the SNR on the SVs is good enough, but there's something
preventing the fix from happening.
Maybe it's because it's a cold start, it needed to run for a while to
acquire the almanac or something.

I've got 4 NEO-7M-C modules hooked up to 7 beaglebone greens, side by

I've got gpsd running, and I'm looking at the output of cgps and/or
gpsmon, as well as ppstest
Some emit NMEA sentences, others binary (ublox?) strings?
Some get a fix and start toggling the 1pps line, others don't.
Is there some command string one can send to them to put them into a known
state (cold reset?) - the one that's working the best (I.e. has a fix AND
toggles 1pps) seems to be putting out binary strings (when viewed with
gpsmon).
