利用GSM模塊SIM100開發(fā)短信收發(fā)系統(tǒng)

1、無利用 GSM 模塊 SIM100 開發(fā)短信收發(fā)系統(tǒng)利用 GSM 模塊 SIM100 開發(fā)短信收發(fā)系統(tǒng)一.引言在開發(fā)遠程通訊控制系統(tǒng)時，利用現有的 GSM 網絡是一個很不錯的選擇。這里利用 PC 串口控制 GSM SIM100 模塊進行收發(fā)短消息來實現遠程通訊。二.SIM100 通訊協議1.COM1 或 COM2 以 9600,N,8,1 格式通訊2.DTR 和 RTS 須置有效。3.打開監(jiān)控軟件后，須對 TE(terminal equipment)初始化。AT CR(0 x0d),LF(0 x0a) 反饋：xxOKxxATE0 CR(0 x0d),LF(0 x0a) 反饋：xxOKxxATS
