通过visual basic6调制解调器自动检测 [英] Modem auto detection through visual basic6

问题描述

此代码也连接调制解调器并发送消息。但我想得到正确的端口名称onmich Modem attatch，如com5。我怎么能这样做？

This code connect the Modem and send message also.But i want to get Correct port name onwhich Modem attatch such as com5.How can i do this ?

Private Sub Timer1_Timer()
   Dim FromModem$
   On Error Resume Next
   For i% = 1 To 6
      MSComm1.CommPort = i%
      If MSComm1.PortOpen = False Then
         MSComm1.PortOpen = True
         MSComm1.InBufferCount = 0
         Label8.Caption = " PORT " & i%
         pb1.Value = pb1.Value + 10
         List2.AddItem i%
         Text1.Text = "Searching Modem Port" & i%
         MSComm1.Output = "AT" + Chr$(13)
         Sleep 4000
         If MSComm1.InBufferCount Then
            FromModem$ = FromModem$ + MSComm1.Input
            If InStr(FromModem$, "OK") Then
               MsgBox "Modem has Found" & i%
               Beep 400, 300
               Timer1.Enabled = False
               Exit For
            End If
         Else
            MSComm1.PortOpen = False
         End If
      End If
   DoEvents
   Next i%
   If i% > 6 Then
      Timer1.Enabled = False
   End If
End Sub

推荐答案

On 错误 恢复 下一步
对于 i％= 1 至 6
MSComm1.CommPort = i％
如果 MSComm1.PortOpen = False 然后
MSComm1.PortOpen = True
MSComm1.InBufferCount = 0
Label8.Caption = PORT& i％
pb1.Value = pb1.Value + 10
List2.AddItem i％
Text1.Text = 搜索调制解调器端口& i％
MSComm1.Output = AT + Chr

On Error Resume Next For i% = 1 To 6 MSComm1.CommPort = i% If MSComm1.PortOpen = False Then MSComm1.PortOpen = True MSComm1.InBufferCount = 0 Label8.Caption = " PORT " & i% pb1.Value = pb1.Value + 10 List2.AddItem i% Text1.Text = "Searching Modem Port" & i% MSComm1.Output = "AT" + Chr

（ 13 ）
睡眠 4000
如果 MSComm1.InBufferCount 那么
FromModem

(13) Sleep 4000 If MSComm1.InBufferCount Then FromModem

= FromModem

= FromModem
