利用GSM模块SIM100开发短信收发系统

1、无利用 GSM 模块 SIM100 开发短信收发系统利用 GSM 模块 SIM100 开发短信收发系统一.引言在开发远程通讯控制系统时，利用现有的 GSM 网络是一个很不错的选择。这里利用 PC 串口控制 GSM SIM100 模块进行收发短消息来实现远程通讯。二.SIM100 通讯协议1.COM1 或 COM2 以 9600,N,8,1 格式通讯2.DTR 和 RTS 须置有效。3.打开监控软件后，须对 TE(terminal equipment)初始化。AT CR(0 x0d),LF(0 x0a) 反馈：xxOKxxATE0 CR(0 x0d),LF(0 x0a) 反馈：xxOKxxATS
