Description: 鉴于传统波形发生器的不足，采用数字合成技术构成任意波形发生器，此波形发生器可以产生任意波形的周期信号，能灵活控制信号的频率幅值，相位，并在很宽的范围内快速切换频率，具有高分辨输出，运用DDS技术构建频率信号源，可获得连续精确调整的信号频率，幅值相位控制方便，存储容量大；AWG占微机系统资源少，通用性好，具有较强的移植性和很高的性能价格比。
研究的内容是利用数字频率合成技术构成任意波形发生器，且通过RS232串行接口传到PC，供PC机管理。
-in traditional waveform generator insufficient use digital synthesis techniques constitute arbitrary waveform generator, This waveform generator can produce arbitrary waveform cycle signal, the control signal flexibility in the frequency of the amplitude, phase, and the very broad scope of the rapid switching frequency, with high-resolution output, using DDS Construction frequency signal source, available for precise adjustment of the signal frequency, amplitude-phase convenient control, storage capacity; AWG for computer systems, fewer resources, common good, with a strong transplantation and high cost performance. The research project is the use of digital frequency synthesis technology constitute arbitrary waveform generator, and through the RS232 serial interface reached the PC for PC

Description: USB作为一种新的PC机互连协议，使外设到计算机的连接更加高效、便利。这种接口适合于多种设备，不仅具有快速、即插即用、支持热插拔的特点，还能同时连接多达127个设备，解决了如资源冲突、中断请求（IRQs）和直接数据通道（DMAs）等问题。因此,越来越多的开发者欲在自己的产品中使用这种标准接口。而RS232是单个设备接入计算机时，常采用的一种接入方式，其硬件实现简单， 因此在传统的设备中有很多采用了这种通信方式。 一般的IC卡门禁考勤系统也使用RS232接口与PC机通信。如果将USB技术应用于IC卡门禁考勤系统与PC机之间的数据通信，这样，不仅能使IC卡门禁考勤设备具备USB通信的诸多优点，而且对PC机而言还可以节余1个RS232串口为其它通信所用。-err

Description:
RS232.C was written to provide all of the basic functionality needed
to employ serial I/O in any application written with Borland C
language compilers. Some features are:
1. Ease of use. No assembly language or library files are used and a simple "#include" statement is all that is required to access all of the functions provided.
2. Both input and output are buffered and interrupt driven for efficiency.
3. Serial ports 1 - 4 are supported on PC, AT and PS/2 compatibles.Chained interrupts used on port 3 and 4 are allowed for so as not to interfere with devices such as a mouse or printer. Transmission speeds of 110 to 115200 baud are available.
4. Detection and utilization of hardware buffered UARTs (NS16550AF
etc.) found in some machines is automatic.
5. Interrupt driven hardware and XON/XOFF flow control is provided for.
6. All source code is included. RS232.C can be used with all memory
models.
