本文介绍了一种适用于无线信道Modem的软件方案。使用该软件可以灵活方便地利用无线信道实现计算机间点对点通信，也可以应用于其他数据移动通信系统。该软件采用C语言进行编制。Modem数据速率为1200／2400bit/s，可选用同步／异步方式进行传输。具有握手、文件收发、请求重传等功能。
This article describes a software solution for wireless channel Modem. Using the software can be flexible and convenient to use wireless channels to achieve point-to-point communication between computers, but also can be applied to other data-mobile communication systems. The software is written in C language. Modem data rate of 1200 / 2400bit / s, optional synchronous / asynchronous transmission. Has a handshake, send and receive files, request retransmission and other functions.
