[讨论] 请各位高手指点关于AT命令的书写方法

[复制链接]
发表于 2006-10-27 20:07:50 | 显示全部楼层 |阅读模式
我现在在做的是让两台手机通过AT命令让A机控制、操作B机。
出现的问题是:从A机发给B机的AT命令只响应了两次,其他时间都不响应,因此,请问是否是我输出的AT命令的书写格式不正确?
前提:1、通过超级终端,手机响应AT命令都是正常的。(从电脑——》A机 ——》B机,B机响应AT命令也是正常的,说明硬件连接正确)。
          2、让A机发送字符串给B机,在B机上显示要传输的字符串,显示结果也是正确的,这说明串口参数配置没问题。
         3、我现在尝试了以下几种操作,都不行,请帮看下,并指点。谢谢!
