Description: 第一步：了解串口通信原理
串口通信的概念非常简单，串口按位（bit）发送和接收字节。尽管比按字节（byte）的并行通信慢，但是串口可以在使用一根线发送数据的同时用另一根线接收数据。它很简单并且能够实现远距离通信。比如IEEE488定义并行通行状态时，规定设备线总常不得超过20米，并且任意两个设备间的长度不得超过2米；而对于串口而言，长度可达1200米。
典型地，串口用于ASCII码字符的传输。通信使用3根线完成：（1）地线，（2）发送，（3）接收。由于串口通信是异步的，端口能够在一根线上发送数据同时在另一根线上接收数据。其他线用于握手，但是不是必须的。串口通信最重要的参数是波特率、数据位、停止位和奇偶校验。对于两个进行通行的端口，波特率, 数据位, 停止位, 奇偶校验位等这些参数必须匹配.

Description: QuickReport 是用于BCB和Delphi的一款报表组件，可以简单快速的输出数据库报表。QuickReport 支持创建打印预览以免浪费纸张，支持导出数据为其他文件格式如ASCII文本、逗号分割值的文件和HTML。QuickReport 本身由 Delphi 编写，支持Delphi 所有操作数据库的模式。因此您可以将它用于旧式的基于BDE 的数据库如Paradox 和 dBase，用于多层应用环境的客户端数据表，新的Delphi 5 ADO 和 Interbase Express 组件及第三方可选数据库如Apollo。如果您需要，甚至可以用QuickReport 格式化部件打印非不是存储在数据库里的数据。-QuickReport for BCB and Delphi, a reporting component that can output simple and fast database reports. QuickReport support the creation of print preview to avoid wasting paper, to support export data to other file formats such as ASCII text, comma-separated value files and HTML. QuickReport itself is prepared by Delphi to support all operations Delphi database model. So you can use it for the old BDE-based databases such as Paradox and dBase, multi-application environment for the client-side data table, the new Delphi 5 ADO, and Interbase Express components and an optional third-party databases such as Apollo. If you need to, even the non-printing parts with the QuickReport format is not stored in the database data.
