# Check ModemManager for pending SMS/MMS messages clogging its queue.
# Until mobile Linux natively supports MMS messages, ModemManager is
# needed along with Janky MMS (https://git.sr.ht/~amindfv/jmms) to get
# your messages and flush the queue; if the queue gets clogged you don't
# get incoming messages anymore.

# Usage: run this in your .bashrc so it'll print in your new terminal
# session to remind you that messages are pending.
