What is mdmAlarmScan?

An 8-byte alarm bitmap read from the modem, where individual bits flag conditions like loss of DTR, no TXD/RXD transitions, modem fallback, power-up, poor signal quality, DCD loss, configuration checksum error, call failure, call-length or retrain-threshold exceeded, ring-no-answer, an active remote configuration session, and test timeout.
