A thermistor inside the modem (monitored by the modem CPU firmware) causes flow
control to be activated should the internal temperature reach 75ºC (167ºF) as
measured at the radio. Flow control is released when the temperature falls below 75.
Should the temperature of the radio reach 80ºC (176ºF), the modem terminates the
connection in order to protect components and avoid drifting outside radio
specifications.
