你用串口调试助手把监听到的指令，一条一条发给plc，然后慢慢研究吧

哈哈，太轮廓了，能不能详细点，不如说用VB去怎么写个枚举的例子

vb枚举就简单了，
串口把
COM1 Write(asc): 4(Bytes)ATZ
COM1 Write(asc): 9(Bytes):0111EE



COM1 Write(asc): 17(Bytes):01010C2D0001C4



COM1 Write(asc): 17(Bytes):01670010000583



这些数据发出去

然后不停的替换下面一句中的密码
COM1 Write(asc): 23(Bytes):0164010D0431323334BF  //输入正确密码（1234）

读返回的值和

COM1 Read(asc): 8(Bytes) :0164010
COM1 Read(asc): 8(Bytes) D04CFCEC

比较，如果通过就把密码记下来就行了
