# ModemManager's quick suspend/resume mode (fp6 repo journal/power/, 2026-10-14):
# on logind's PrepareForSleep the modem is set "terse" (the NAS signal-info,
# system-info and DSD system-status subscriptions are dropped, calls and
# texts still reach us) and on resume its state is synchronised. Without it
# the modem's indications end a deep suspend cycle every few seconds; with
# it a cycle runs to its wake alarm while the modem stays registered. The
# option still carries MM's --test- prefix; it is the only switch for the
# daemon's built-in terse mode.
