如何用gprs段信貓發短信

項目需求：由於上週機房溫度過高造成機房失火，要求實現溫度預警程式。

設備：感溫器（串口通訊，每四秒將當前溫度發送到串口）

          GRPS modem （usb模擬串口通訊，通過at指令實現短信發送）

          SERVER一臺

            at command 流程大致如下 :

                     1. atz                       (reset modem)

                     2. at+cpms=”MT” (select message storage)

                     3. at+cscs=”ASCII” (select TE character set

                     4. at+cmgw=0939112781 <cr> Your SMS Message here (0939112781 is my phone number, write to storage and get an index, ie 5)

                     5. at+cmss=5 (5 is the index you got at step 4, send message)

                     6. at+cmgd=5 (5 is the index you got at step 4, delete message to prevent the storage full).

核心代碼:

            MsgBox("Sorry,ERROR", vbOKOnly + vbCritical, "ERROR")
        End If

        AxMSComm1.PortOpen = False

-----------------------------------------------------------------------------------------------------------------------------

        Dim Ctn As Integer
        Dim Buffer$
        Ctn = 0
        Do
            Application.DoEvents()

        Loop Until (InStr(Buffer$, "OK" & vbCrLf)) Or (InStr(Buffer$, "ERROR" & vbCrLf))

        If InStr(Buffer$, "+CMGW:") Then
            Ctn = InStr(Buffer$, "+CMGW:")
            Out_STR = Trim(Mid(Buffer$, Ctn + 6, 4))
