端口专家是一个优秀的端口（串口、并口）监视、调试程序，有以下基本功能： 1.能动态设置各种通讯速率、奇偶校验、数据位、停止位和流控； 2.可以16进制形式自动显示接收到的数据，并能同时发送ASCII码（包括中文）和16进制字符串，可以任意设定自动发送周期,定时发送数据； 3.能将接收数据保存成文本文件,便于比较观察；并能发送任意大小的数据文件（以二进制形式发送）； 4.能自动保存设置参数，无需每次重新设置。-port experts is a good ports (serial, parallel) monitoring, debugging procedures, the following basic functions : 1. Dynamically created various communications rate, parity, data bits, stop-and flow control; 2. May 16-band automatic form of data received and at the same time sending ASCII (including Chinese) and 16 string band can be set to automatically send arbitrary cycle, regularly send data; 3. preservation can receive data into text files, facilitate comparison of observation; and the ability to send any size of paper (in binary form Send); 4. Save the settings automatically parameters, each without re-instated.
