利用Java实现串口全双工通讯
DL : 1
一个嵌入式系统通常需要通过串口与其主控系统进行全双工通讯,譬如一个流水线控制系统需要不断的接受从主控系统发送来的查询和控制信息,并将执行结果或查询结果发送回主控系统。本文介绍了一个简单的通过串口实现全双工通讯的Java类库,该类库大大的简化了对串口进行操作的过程-an embedded system usually through its serial port control system for full-duplex communications, For example, a pipeline control system to accept the need to constantly sent from the main control system to control the inquiries and information, implementation will be the outcome or results of inquiries sent to the control system. This paper presents a simple realization through full-duplex serial communications Java class libraries, the library greatly simplifies the operation of the serial port for the process

udptransport
DL : 0
基于UDP实现简单的可靠数据传输 由于数据是在不可靠的信道上传输的,因此数据在信道上传输时可能会发生比特错误,数据丢失。Rdt3.0及之前的版本都是停止—等待协议,它限制了网络底层硬件的能力。为克服这个问题引入了流水线技术,两个能恢复流水线中的错误的基本方法:第N个分组重发和选择性重复。综上,要实现差错编码,顺序号,计时器,分组确认,滑动窗口,拥塞控制。-simple UDP based on the reliable data transmission of data is not reliable transmission of the channel, therefore the data transmission channel may occur bit error, data loss. Rdt3.0 and earlier versions are stop-wait for the agreement, which limits the underlying network hardware capabilities. To overcome this problem the introduction of pipeline technology, both of which can restore pipeline error in the basic methods : section N to a re-issued and selective repeat. In sum, to achieve error coding, sequencing, the timer, a confirmation, sliding window, congestion control.

这是一个很简单的 shell 程序。是我在winshell中把shell功能的代码提取出来的。里面有较好的管道编程方法-This is a very simple shell. I put in winshell were shell functions from the code. There are better ways pipeline Programming
