WINCE+6410 拨号上网

發布時間：2025/4/16 编程问答 23 豆豆

生活随笔收集整理的這篇文章主要介紹了 WINCE+6410 拨号上网小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

我們現在的模塊用的是USB接口，然后模擬成一個COM6進行通信，在CE的:?控制面板->網絡連接?里要新建一個連接，選擇“撥號連接”然后設置好區域代碼，還有附加解調器命令+CGDCON,"IP","CMNET"，modem選擇，與modem的串口通信速率等信息，然后連接，這上可以實現上網。

???添加的CE組件有：

CoreOS->Windwos CE devices->commuication services and newworking->networking-wide area network ->Dial up networking

????????->Autodail

????????->TAPI

????????->Virtual Private Networking(VPN)

???我們現在要實現的功能是，讓用戶只點擊一個ICON，就能實現上網，不用這么麻煩去設置。

???我寫了一個應用，通過RAS?接口調用可以實現撥號上網功能，但是，必須指定一個已建立并設好參數的連接，

???所以，還得在程序中創建一個網絡連接才行，因為我們需要的簡化的其實就是讓用戶輸入附加撥號命令（+CGDCONT=1，"IP"，"CMNET"那么一長串，其實只需要用戶輸入一個APN和一個電話號碼就OK了）。因為針對不同的運營商，這個APN是不同的，所以這個要能給用戶設置。

查MSDN得知，調用RasSetEntryProperties加上RasSetEntryDialParams可以實現，但是這種方法貌似設置不了modem的串口屬性、附加撥號命令等一些信息，

用RasSetEntryProperties設置一個Entry的屬性的時候，如果Entry的參數中指定的EntryName已經存在了，那么就更改已有的Entry的設置，如果不存在，則創建了一個新的Entry，這樣就實現了創建撥號連接的功能，

MSDN上關于RasSetEntryProperties函數中的倒數第二個參數的解釋說明是說它是一個指向包含設備配置信息的緩沖區的指針，是關于設modem的串口屬性、附加撥號命令等，

但是要查閱關于這個配置信息的更多詳細內容，就要看TAPI相關的lineGetDevConfig函數，但是TAPI相關知識是相當龐大的一個體系，因為項目時間很緊，

直接在WINCE系統里的控制面板下，進入“網絡和撥號連接”，手動新建一個能撥通上網的連接，我命名為“3GCONNECT”

?然后寫測試程序，調用RasGetEntryProperties（）函數，在倒數第二個參數傳一個數組，然后打印出正確設置時的lpb里面的值，結果如下：

-??????????????????lpb?????0x001aed00 "0"???????unsigned char[436]

[0x44]?????????0x00 ''??????????unsigned char后面的全為0

經過改不同的參數然后以上面的方法打出這個參數傳回來的值，總結出

所以總結出以下結構體：

typedef struct

{?????????????????????????????//offerset

?U16INT??Reserved1;???????????????//0???????????????一般為0x30

?U16INT??WaitForCreditcard;???????????//0x02?等待信用卡音頻信號時間,單位?；秒

?U16INT??WaitForConnect;???????//0x04??????這時間之內未建立連接，則取消撥號

?U16INT??Reserved2;??????????????//0x06????一般為0

?UINT8????Flowcontrol;???????????// 0x08??串口參數：流控制，0 --?無?0x20?軟件??0x10?硬件

?UINT8????Unknow1;??????????????// 0x09????一般為1，暫時還不知它是什么作用

?U16INT??Reserved3;??????????????// 0x0a???= 00

?U16INT??BaudRate;???????????????//0x0c?串口波特率例如?19200

?U16INT??Reserved4;??????????????// 0x0e???=0

?U16INT??Configbit2;?????// 0x10??//?對應“設備屬性”對話框中的“手動撥號（用戶提供撥號串）”，如果為0x04?表示選上此項

?UINT8????DataBit;?????????????// 0x12??串口數據位?例如:8位

?UINT8????StopBit;?????????????// 0x13??停止位00- 1位，??02 - 2位

?UINT8????ParityBit;???????????// 0x14??奇偶校驗位00-無，01奇數，02偶數，03標記，04空格

?UINT8????Reserved5;??????????// 0x15??i don't know it's function

?TCHAR????AttachedCmd[210];??// 0X16??從這開始是附加解調器命令，例如"+CGDCON=1,IP,COMNET"

?????????//注意:本人使用的是wince6.0,所以這個長度為436byte,其它平臺可能會不一樣，網上有牛人測出WM的是一百多的

}RASlpdInfo;

用這個結構在AttachedCmd中填入附加撥號命令，就可以了

??DWORD dwSize,

????dwError;

????TCHAR szError[100];

???RASlpdInfo lpb;

???unsigned?long?lpbSize =?sizeof(RASlpdInfo);

????memset(&lpb,0,lpbSize);

????RASENTRY RasEntry;

????dwSize =?sizeof?(RASENTRY);

????memset (&RasEntry, 0, dwSize);

????RasEntry.dwSize = dwSize;

wcscpy(RasEntry.szDeviceName,L"CDMAModem");

wcscpy(RasEntry.szDeviceType,L"modem");?????????????????//#define RASDT_Modem?????????TEXT("modem")?????// Ras.h

RasEntry.dwCountryCode = 86;?//國家代碼

wcscpy(RasEntry.szAreaCode,L"10");????

TCHAR szLocalPhoneNumber[RAS_MaxPhoneNumber + 1] = {0};

wsprintf(szLocalPhoneNumber,L"%s",LocNum);??//-------------------容易出問題的地方

wcscpy(RasEntry.szLocalPhoneNumber,szLocalPhoneNumber );

RasEntry.dwfOptions= 4194304;//RASEO_ProhibitEAP|RASEO_RemoteDefaultGateway;??;//4194304;0x00400208;//

RasEntry.dwfNetProtocols= RASNP_Ip;//4; Negotiate TCP/IP

RasEntry.dwFramingProtocol= RASFP_Ppp;//1; // Point-to-Point Protocol (PPP)

lpb.Reserved1 = 0x30;

??????lpb.WaitForCreditcard = 0;

??????lpb.WaitForConnect =120;

??????lpb.Reserved2 = 0;

??????lpb.Flowcontrol = 0;

??????lpb.Unknow1 = 1;

??????lpb.Reserved3 = 0;

??????lpb.BaudRate = 19200;

??????lpb.Reserved4 = 0;

??????lpb.Configbit2 = 0;

??????lpb.DataBit = 8;

??????lpb.StopBit = 0;

??????lpb.ParityBit = 0;

????TCHAR szATComd[420] = {0};

????wsprintf(szATComd,L"+CGDCONT=1,$IP$,$%s$",lpszAPN);

????szATComd[11] = 0x22;?//?雙引號"

????szATComd[14] = 0x22;

??????szATComd[16] = 0x22;

????szATComd[22] = 0x22;

????wcscpy(lpb.AttachedCmd,szATComd);

???if?(dwError = RasSetEntryProperties (NULL, lpszName,

????????????????????????&RasEntry,?sizeof?(RASENTRY),(LPBYTE)(&lpb), lpbSize))

????{

????????wsprintf (szError, TEXT("Unable to create the phonebook entry.")

????????TEXT(" Error %ld"), dwError);

????????return?FALSE;

????}

注意，WINCE6.0調用了RasSetEntryProperties()之后，就可以在控制面板的連接管理里看到這個連接圖標了，但是，如果是在WM系統，那就得再做下面的工作才能看得到圖標。

機器中控制面板的”管理現有連接“對應注冊表中

HKEY_LOCAL_MACHINE//Comm//ConnMgr//Providers//{7C4B7A38-5FF7-4bc1-80F6-5DA7870BB1AA}//Connections

[Connections]下的集合；

[Enabled]:??????是否為默認連接；

[RequirePW]??是否需要用戶名與密碼

[DestId]：??????表示屬于哪種類型的連接；

[ConnectionGUID]：表示連接的標識ID，

拔號時獲得當前狀態

如果想在拔號時獲得當前狀態，可以這樣：

攔截PreTranslateMessage這個消息事件，截獲WM_RASDIALEVENT消息即可達到目的

BOOL CMy3GControlerDlg::PreTranslateMessage(MSG* pMsg)

{

if(pMsg->message == WM_RASDIALEVENT)

??switch(pMsg->wParam)

??{

?case???RASCS_OpenPort:

??????pShowstate->SetWindowTextW(_T("打開端口…"));

????break;??

?case???RASCS_PortOpened:?

??pShowstate->SetWindowTextW(_T("端口已打開…"));

?????break;??

?case???RASCS_ConnectDevice:??

?????break;??

?case???RASCS_DeviceConnected:

??pShowstate->SetWindowTextW(_T("設備已連接…"));

?????break;??

????case???RASCS_Authenticate:?

??pShowstate->SetWindowTextW(_T("驗證用戶及密碼…"));

?????break;??

????case???RASCS_Authenticated:??

??pShowstate->SetWindowTextW(_T("用戶及密碼已通過驗證"));

?????break;??

?case???RASCS_Connected:

????????pShowstate->SetWindowTextW(_T("已連接"));

?????break;??

?case???RASCS_Disconnected:??

?????pShowstate->SetWindowTextW(_T("斷開連接"));

?????break;??

?default:??

?????return???(LRESULT)0;

??}

?return?CDialog::PreTranslateMessage(pMsg);

}??

RAS撥號的同步和異步問題

?dwRet = RasDial(NULL,NULL,&rdParams,0L,NULL,&m_hRasConn);//同步
?dwRet = RasDial(NULL,NULL,&rdParams,0L,RasDialFunc,&m_hRasConn);//異步回調?--只支持在PC
?dwRet = RasDial(NULL,NULL,&rdParams,0xFFFFFFFF,this->m_hWnd,&m_hRasConn); //異步消息--支持PC、CE

如果同步，可用線程監視同步過程，

異步：只在使用了PreTranslateMessage才成功

所以，在CE系統里，要實現連接狀態顯示，那就得使用

?dwRet = RasDial(NULL,NULL,&rdParams,0xFFFFFFFF,this->m_hWnd,&m_hRasConn);

撥號連接

void DialRAS(LPVOID Hahandle,LPWSTR ConnectionName,LPWSTR PhoneNumber)

{

????????RASDIALPARAMS RasDialParams;

?????????BOOL???????????????????fPassword;

?????memset (&RasDialParams, 0, sizeof (RASDIALPARAMS));

?????????RasDialParams.dwSize??= sizeof(RASDIALPARAMS);

??wcscpy(RasDialParams.szEntryName,ConnectionName);??//已建連接的名字

????TCHAR szLocalPhoneNumber[RAS_MaxPhoneNumber + 1] = {0};

????wsprintf(szLocalPhoneNumber,L"%s",PhoneNumber);

????wcscpy(RasDialParams.szPhoneNumber,szLocalPhoneNumber);

?????????wcscpy(RasDialParams.szCallbackNumber, _T(""));?

?????????wcscpy(RasDialParams.szUserName, _T(""));?

?????????wcscpy(RasDialParams.szPassword, _T(""));?

?????????wcscpy(RasDialParams.szDomain, _T(""));

CMy3GControlerDlg* hthisp =(CMy3GControlerDlg*)Hahandle;

DWORD hRasRet = 0;

?// Try to establish RAS connection.

hRasRet = RasDial (NULL,????????????// Extension not supported

??NULL,????????????// Phone book is in registry

??&RasDialParams,??// RAS configuration for connection

??0xFFFFFFFF,??????// Notifier type is a window handle

hthisp->m_hWnd,??// Window receives notification message

??&hRscon);

??printf("hRasRet == %d ", hRasRet);

????if ( hRasRet != 0) // Connection handle

????{

????????printf("Could not connect using RAS, error == %d ", GetLastError());

????}

}
