串口调试，负责数据收发，带有串口自选，波特率选择(Serial debugging assistant)

hdlc设计，包括flag检测，插0、串并转换等设计，采用verilog编程。(hdlc design, using verilog)

清除串口冗余。当下位机偶然有乱码出现时，在新的通讯开始先清除缓冲区冗余信号，然后开始通讯，可以保证通讯更稳健(Clear serial redundancy. Current-bit machines have occasionally garbled when, in the new communications start to clear the buffer zone redundant signal, and then began to communications, to ensure more robust communication)

说明：  STC15W4K48S4串口打印程序,利用硬件串口..(use; utilize; make use of; take advantage of)

串口通信高级编程，为Visual C++.NET网络与通信高级编程范例第八章配套源代码 (serial communication programming, for Visual C.NET network and communications senior programming paradigm Chapter VIII supporting source code)

介绍了一种点位运动控制器的设计，该控制器可以控制步进和伺服电机。该运动控制器以 STM32F103 为主控微处理器，实现了电机起停的加减速控制，扩展了 RS485 串行通信接口，设计了限位保护电 路，移植了嵌入式实时操作系统μC /OS-Ⅱ，通过μC /OS-Ⅱ来调度运动控制器的多个任务，设计了串口通信协议， 可以方便组成多轴控制系统.(Describes the design of a point of the motion controller, the controller can control a stepper and servo motors. The motion controller controlling microprocessor STM32F103, acceleration and deceleration control the motor starts and stops, extended RS485 serial communication interface, designed to limit protection circuits, transplantation of embedded real-time operating system μC/OS-Ⅱ μC/OS-Ⅱ scheduling multiple tasks of the motion controller, designed a serial communication protocol, can easily form a multi-axis control system.)

一只菜鸟的串口程序，建议初学者可以看看 希望可以对你们有点用(a serial newcomers procedures, the proposed beginners can hope to see you with a bit)

用 C++ 编写的 发送 接收串口工其软件，好用，可以参考一下(C++ prepared by the transmission and receiving serial software, good use, you can refer to)

modbus协议,中文文档,讲解十分详细,方便参看查询()
