Description: 用c语言编写串口程序
在当今,流行的编程软件种类繁多，它们编程方便、易于维护，但是在与硬
件直接打交道和编制系统软件时却束手无策，于是C语言就有了用武之地。C语言
作为汇编语言与高级语言之间的一种过渡语言，兼有汇编语言的高效和高级语言
的方便。
在通讯中，为了保证行运安全可靠，标准的串行口必须具有许多握手信号和
状态信息。这是因为通讯的各个计算机CPU速度不一样（这会导致“错帧”）以
及发送机发送数据速度比接收机接收速度快（这会导致“过冲”）。为解决这个
问题，我们采用一个简单的握手信号，即发送机每次仅发送半个字节（低4位）
的数据，而另外半个字节（高4位）则用来传送信息。我们可以对信息位（高4位）
进行如下简单的编码：
0H：发送的是新的半个字节数据
1H：重新发送上次传送错误的数据
2H：文件名结束
3H：文件结束
这样，每当发送机发送一个字节以后，就等待接受机发回送信号，这回送信号就
是发送机发送过来的那个字节。发送机接收到回送信号后，把它与刚发送的字节
相比较，如果相同，就发送新的半个字节，否则就重新发送。新数据与旧数据通
过信息位来区分。下面就是用C语言编写控制串行口的程序。

Description: 由一台 PC （线程）向另一台 PC （线程）发送数据包，界面应显示出双方帧个数变化，帧序号，发送和接受速度，暂停或重传提示等，界面中必须动态显示数据帧的发送情况和接受情况，包括 在相应窗口详细 显示相应的 ACK 和 其他收发数据帧后发出的消息 ，以表明模拟协议的正确运作过程。
• 接收方及发送方应具有按序收发帧的能力；
• 接受方应有固定大小的滑动窗口，并对收到信息缓存。当发送方速度过快或帧丢失（超时），接受方应发送消息，要求暂停或重传（停 -- 等协议）；
• 发送方发送速度应可以调节，并可以暂停或重发；
• 发送方重传时可仅重传需要的（丢失的）幀；
• 以上几个功能应可视，要求简单界面。

Description: This application allows any 2 persons on the LAN/Intranet (possibly Internet too) to have video conference. There are several video conference applications existing today. Each has its own performance enhancement techniques. The major problem in video conference is that the size of video frames is too big for transmission. Hence the performance is based on the codec used for encoding and decoding the frame. I am using Fast h263 Encoder library which gives better compression rate at high speed. This application can also be used on the Internet with little modification.
