Upgrading the MT2834MR Firmware
The MT2834MR has a Flash PROM which contains firmware code for the hardware. At various times,
Multi-Tech may add enhancements and/or fixes to the firmware. The flash technology used in the
MT2834MR allows these upgrades to be loaded directly into the PROM chip through the modem’s serial
port.
