processor and Modem are connected using a serial port or USB. To achieve data transmission and control Modem at the same time in a hardware serial port path, the multiplexing protocol (GSM TS07.10) must be implemented ), at the underlying layer, we virtualize two serial ports, one for the CMD channel and the other for the DATA channel. All telephone control channels are on this channel. RIL, Radio Interface Layer. This layer is a protocol transfer la

need for the ashes of the programmer, the C language bottom-level research and development, as well as the bottom of the Android system, must have in-depth research.Why are there 127 of them? Because the computer hardware was designed to consider the maximum number of USB interface 2 is 8, that is, 128, and itself to occupy one, so a computer hardware limit in theory only support 127
