CDC ACM
USB CDC (Communications Device Class) ACM (Abstract Control Model) is a vendor-independent publicly documented protocol that can be used for emulating serial ports over USB.
As opposed to a USB stack, implemented in software-only or a dedicated UART to USB bridge, such as FTDI or Prolific chips.
The radio must be placed into firmware update mode.
Press and hold both the PTT button and the orange PF3 button and turn on the radio.
The red LED light near the on/off switch will blink slowly. Theradio is now ready to accept the firmware.
Note that this csv file has the callsign concatenated with the name and
displayed in the "name" field and the "callsign" field is left blank.
This allows for the way that the Anytone displays the data on the radio's screen.

SCT3258 is a low power high performance base band processor supporting DPMR and DMR
protocol. With an external codec (audio band ADC and DAC), it completes the entire physical
layer and data link layer, and most of the call control layer processing of DPMR and DMR
protocol
