用VB6 mscomm写的短信收发，无法收短信
各位大虾：
因为最近看了很多短信收发的编写，从网上下载了一下短个收发源代码，问题是可以发送，但无法收短信！请各位检查检查，指导下！谢谢！
具体代码如下：
Dim SendSuccessCount As Integer
Dim SendFailedCount As Integer
Dim ReceiveCount As Integer
Dim WorkFlag As Boolean
Dim ReceiveData As String
Dim SendSuccess As Integer '-1等待；0失败；1成功
Dim ReceiveSuccess As Integer '-1等待；0失败；1成功
Private Sub Command1_Click()
RequestRecMsg MsgIndex.Text
End Sub
Private Sub Form_Load()
SmsInit 6, "9600,n,8,1"
End Sub
Private Function SmsInit(Port As Integer, setstr As String) As Boolean
SmsInit = False
If SmsOpen(Port, setstr) = False Then Exit Function
WorkFlag = True
SendSuccessCount = 0
SendFailedCount = 0
ReceiveCount = 0
ReceiveData = ""
SendSuccess = 0
ReceiveSuccess = 0
SmsInit = True
End Function
Private Function SmsSend(MoblieID As String, TxtMessage As String) As Boolean '被timer1_timer调用
Dim TxtMsg As String
SmsSend = False
If WorkFlag = False Or SendSuccess = -1 Then Exit Function
'编码
TxtMsg = Encode(TxtMessage)
If MSComm1.PortOpen Then
MSComm1.Output = "AT+CMGS=" + Chr(34) + MoblieID + Chr(34) + Chr(13) '送出短信目的号码
MSComm1.Output = TxtMsg + Chr(26) '送出已编码后的短信内容
SendSuccess = -1
SmsSend = True
End If
End Function
Function SmsOpen(Port As Integer, Setings As String) As Integer '被opensms_click 调用
'打开端口号码
On Error GoTo ErrHandle
SmsOpen = False
If MSComm1.PortOpen Then MSComm1.PortOpen = False
MSComm1.CommPort = Port
MSComm1.Settings = Setings
MSComm1.PortOpen = True
If MSComm1.PortOpen Then
SmsOpen = True
MSComm1.Output = "ATE0" + Chr(13) + Chr(10)
MSComm1.RThreshold = 1
MSComm1.Output = "AT+CMGF=1" + Chr(13) + Chr(10)
MSComm1.Output = "AT+CSMP=4,167,0,8" + Chr(13) + Chr(10)
'上边两行语句作为联机是初始化用的命令
End If
Exit Function
ErrHandle:
MsgBox "错误： " + Str(Err.Number) + Chr(13) + Chr(10) + Err.Description, _
vbOKOnly + vbCritical, App.Title
End Function
[解决办法]
你的代码可以接收数据的。你应该检查AT指令是否正确。
