功能、参数解释
切换到"协议通信状态"命令：
1） 可以用于PC寻找NETDOG硬件；
2） 切换到"协议通信状态"，NETDOG收到该命令，无论出于何种工作状态，都必须切换到"协议通信状态"
切换到"透明传输状态"命令：
该命令使NETDOG切换到透明传输状态
查询硬件版本号命令：
用于查询NETDOG的硬件版本
设置紧急报警电话号码1（必须设置）
设置紧急报警电话号码2（必须设置）
读取紧急报警电话号码1
读取紧急报警电话号码2
设置通信中断报警时间门限（1到10分钟）
读取通信中断报警时间门限
设置报警短信发送次数（1到3次）
读取报警短信发送次数（1到3次）
打开NETDOG的监控和报警功能
将该工作状态记录到EEPROM，上电恢复相应状态
关闭NETDOG的监控和报警功能
