Hi,
GoodDay. I am using O2 XDAII, I am want to send some data through GSM. For that I want to know, GSM is situated in Which Port ?.......
So that i can Open the port(COM1 or Com2) and send the some AT commands into it.
or is there any there way to Open the GSM and send data
Kindly Let me know..
Thanks
regards,
Rajesh. S
Over GSM, you have two options; dial-up and GPRS..
None of these uses COM ports in the way that you are thinking..
GSM is located at COM2. But to enable communication with it on XDA2 you'll need to send IOCTL to RIL. Here is a code from one of my test applications.
Code:
#include "stdafx.h"
int HexToInt(char R)
{
if(R>='0' && R<='9')
return R-'0';
if(R>='a' && R<='f')
return R-'a'+10;
if(R>='A' && R<='F')
return R-'A'+10;
return 15;
}
int Hex2ToInt(char *R)
{
return ((HexToInt(R[0])<<4)|HexToInt(R[1]))&255;
}
bool IsHex(char C)

if(C>='0' && C<='9')
return true;

Hi,
Good Day.. I got your code..... First of all i convey my thanks to you.
I need some more clarification from your side.
Kindly let me know in details
I am not able understand
Why we need to use RIL & IOCTL Funct?
how your sending "AT" Commands in your Code?( explain to me in details) If i want to add some more AT commands like( AT+CSQ or AT^SCKS?) means how do i add these command and where?...
if you have sample code kindly send to [email protected]
anticipating your reply,
Thanks & regards,
Rajesh. S

Using COM port GSM access to change outgoing line
Is it possible to alter the outgoing number (read from the SIM card) on the GSM by accessing the COM port?
Is there a utility that already does this? Is there a way of altering settings/phone to be able to change the outgoing number? Or a ROM image that allows you to do this?
I have no understanding whatsoever of the radio stack, so I wouldn't know where to start if I were to write a utility to do so.
Cheers,
Jason

@jman,
No that is not possible. The reason is that the phone does not send its caller ID over the air. What happens is that a pseudo random number (called TMSI) is assigned to the mobile phone. The mobile phone sends its TMSI for identification and the MSC (Mobile Switching Centre) does the mapping for the TMSI to calling MSISDN (techno term for mobile phone number).
However, if you are a really good programmer and know your phone internal GSM functioning very well. Then you can spoof the TMSI. Meaning, you should listen to the Paging Messages that are being received on the PCH and get the TMSI from them and then generate a CHAN_REQ based on one of those TMSI. If you want to know more about it, then I suggest that you read a document called GSM04.08 from www.3gpp.org .
Please note that whatever I have written above is valid for a GSM/GPRS/EDGE network only.
Regards,
I have a background service DLL running on Windows Mobile 2003 in Services.exe.
I now wish to port it to run in Devices.exe. I have so far been unable to get it to run. Instead when I run the ActivateDevice or ActivateDeviceEx it returns with error 1,2 or 120.
What is required by my DLL to be compatable with Devices.exe?
I have added what I assume are the correct registry settings under HKLM\\Devices\\Name so i can only assume it is something wrong with the DLL itself.
If anyone can assist me with this problem it would be greatly appreciated.
Cheers Gerard
Do I need to use the Developer Platform to create the driver or is Embedded fine?
You can use eVC to create drivers.
To make your driver recognized by OS you should add registry keys:
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\_name_]
"Prefix"="BLA" - 3 CAPS letters, it is your driver prefix
"Index"=dword:00000001
"Dll"="yourdriver.Dll"
And your driver should export functions:
BLA_Close
BLA_Deinit
BLA_IOControl
BLA_Init
BLA_Open
BLA_PowerDown
BLA_PowerUp
BLA_Read
BLA_Seek
BLA_Write
Later you can use CreateFile(L"BLA1:",...) to communicate with your driver. Read MSDN for more.
I have those entries in the registry and my DLL exports those functions.
However, I can not get the DLL to start through ActivateDeviceEx or ActivateDevice. If I reset the device the device freezes and requires a hard reset.
My DLL works fine in Services.exe but must need some changes to operate in Device.exe. The problem being that I can't find any examples where a Device Driver was written in C++ (all .c) and also can't find any examples of a Service being converted to a Device driver.
Any suggestions greatly appreciated
You don't need to call ActivateDexice[Ex] if you have manually added these keys to registry. The reason that your device hangs is in your DLL's entry point or in one of the exported functions. Probably BLA_Init or one of the power functions. You should add diagnostics code that outputs a trace log to SD-card or built-in storage so that you can read this file after hard reset. Or the reason may be that your driver is loaded before the one of the needed drivers, for example SD-card. In this case you should play with the "order" key.
I've wrote several drivers in C++. But none of them used C++ exceptions, I don't know how devices.exe would behave if exception is thrown. And you should remember not to allocate huge arrays/variables on stack.
I've found a small tutorial on MSDN - http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnembedded/html/spotwincerambl.asp
Posted: Wed Mar 09, 2005 18:19
--------------------------------------------------------------------------------
So if I already have the registry entries in do I start the DLL with CreateFile or something similar? I assumed that the DLL was hanging on device startup due to attempting to include an unloaded module but this still occurs when setting Order to 99.
At the moment for testing purposes I am just getting all my exported functions to write to a log file... however none are ever entered. What is the DLL's entry point? Init? PowerUp? An additional method? Have you an example that I could possibly have a look at?
Thanks for your help.
Gerard
The first entry point is DllMain. Then init function is called. Then open when your device is opened. If you have global classes with constructors - constructors are called before DllMain (I have not tested that), one of them may be the reason of crash.
The sample is in the link I gave in the prev. post. or here is a sample driver that is a wrapper around Serial_BTUR.dll
Code:
// Serial.cpp : Defines the entry point for the DLL application.

Thanks for your help. The reason I am porting my Dll from Services.exe to Device.exe is because I need it to run continuosly and when running in Services.exe when the device suspends of course no CPU time. That is, I was hoping to implement the Dll as a driver and catch the PowerDown message and prevent it from happening.
I noticed that in the MSDN example the PowerDown method is void but in yours it returns Bool. To prevent the power down do I convert the method to return a false bool value? Can this functionality be done?
Regards Gerard

Don't always trust MSDN regarding Windows CE. I've taken these prototypes from some of MS own drivers.
You can prevent device from sleeping from your program using this method:
http://msdn.microsoft.com/library/d.../html/ppc_programming_pocket_pc_2002_lfyy.asp
That was the method I used originally to tackle this problem but it consumed too much power leaving the screen in that dimmed state.
I had the understanding that if I implemented my Dll in a device driver the screen could go blank but the device would only go into "sleep" mode where drivers would still receive CPU time as long as they responded to the PowerDown function.
Do you know if this is possible or am I wasting my time?
I don't know. I never worked with power levels. But probably this is possible in driver with functions SetPowerRequirement and DevicePowerNotify. But this would work only if device supports D1 (low on) power mode. Otherwise I think you would not notice any difference with keeping the device always on and shutting down LCD+backlight.
Thanks again for your help.
I have managed to port my service into a device driver but am having trouble handling Power Management issues. It seems as though it is in my Dll attempting to prevent a device suspension which is crashing the device. If I dont attempt to prevent suspend mode or set power requirements the Dll is quite stable. If anyone has any experience with Device driver power management or can point me in the right direction it would be much appreciated.

We have developped an application on WM2002 and WM2003 that use PDA modem to communicate with a remote device.
We worked with QTEK 2020 and QTEK 9090.
Last month we must porting the application on WM2005 (JAMin PDA), but we founded problems with the AT commands sent on the modem.
The code that open the modem is:
// initialize RIL COM
if (!RIL_Initialize(1, NULL, NULL, 0x00040000L, NULL, &m_hRil))
{
error("RIL_Initialize");
ResTMP= 1;
}
// open COM2 (to send AT command to the modem)
m_hCom=CreateFile(CommandPort,GENERIC_READ|GENERIC_WRITE,0,0,OPEN_EXISTING,0,0);
if (m_hCom==NULL || m_hCom==INVALID_HANDLE_VALUE)
{
error("CreateFile()");
m_hCom= NULL;
return 2;
}
// set COM setting
DCB dcb;
if (!GetCommState(m_hCom, &dcb))
{
error("GetCommState");
ResTMP= 3;
}
dcb.BaudRate= CBR_115200;
dcb.ByteSize= 8;
dcb.fParity= false;
dcb.StopBits= ONESTOPBIT;
if (!SetCommState(m_hCom, &dcb))
{
error("SetCommState");
ResTMP= 4;
}
if (!EscapeCommFunction(m_hCom, SETDTR))
{
error("SETDTR");
ResTMP= 5;
}
COMMTIMEOUTS to;
if (!GetCommTimeouts(m_hCom, &to))
{
error("GetCommTimeouts");
ResTMP= 7;
}
to.ReadIntervalTimeout= 0;
to.ReadTotalTimeoutConstant= 200;
to.ReadTotalTimeoutMultiplier= 0;
to.WriteTotalTimeoutConstant= 20000;
to.WriteTotalTimeoutMultiplier= 0;
if (!SetCommTimeouts(m_hCom, &to))
{
error("SetCommTimeouts");
ResTMP= 8;
}
if (!SetCommMask(m_hCom, EV_RXCHAR))
{
error("SetCommMask");
ResTMP= 9;
}
// open RIL2 (radio)
m_hRil= CreateFile(RadioPort,GENERIC_READ|GENERIC_WRITE, FILE_SHARE_READ|FILE_SHARE_WRITE,0,OPEN_EXISTING,FILE_ATTRIBUTE_SYSTEM,0);
if (m_hRil==NULL || m_hRil==INVALID_HANDLE_VALUE)
{
error("CreateFile()");
return 10;
}
// send command to radio handle to turn off the phone and release the modem
DWORD rildevresult;
if (!DeviceIoControl(m_hRil, 0x03000314L,0,0, &rildevresult, sizeof(DWORD), &nReturned,0))
{
error("DeviceIoControl ril 0x03000314L");
ResTMP= 11;
}
// send command to modem to enable it
BYTE comdevcmd[2]= {0x84, 0x00};
if (!DeviceIoControl(m_hCom,0xAAAA5679L, comdevcmd, sizeof(comdevcmd),0,0,0,0))
{
error("DeviceIoControl com 0xAAAA5679L");
ResTMP= 12;
}
The red code not works on WM2005, therefore the radio is not released and the AT commands sent on COM2 not produce.
Sorry...
the red code is:
if (!DeviceIoControl(m_hRil, 0x03000314L,0,0, &rildevresult, sizeof(DWORD), &nReturned,0))
{
error("DeviceIoControl ril 0x03000314L");
ResTMP= 11;
}
It's great!

Some people seem to have solved this. The Universal unlocker on buzzdev.net contains the correct calls. You might want to take a peek at that binary... (IDA required).
bigmac
Hi bigmac, I have not found nothing on buzzdev.net that can help me to solve this problem.
You have any idea how I can found the information in the site buzzdev.net that can help me?
Tank's!
Hi mmarco_hes!
I have the same problem with the "red code" on my WM5 device.
Do you found the reason or a solution for this problem ?
Thank´s in advance.
Regards Jogi
I see COM7 on MDAPro Universal ist GSM/GPRS port. I can open it via createfile, but i can't send DeviceIoControl code:
BYTE comdevcmd[2]= {0x84, 0x00};
if (!DeviceIoControl (m_hCom,0xAAAA5679L, comdevcmd, sizeof(comdevcmd),0,0,0,0))
{
error("DeviceIoControl com 0xAAAA5679L");
return false;
}
What is the real code on MDAPro ?
Hello everyone,
This topic is not new however i never see any thread that has the solution for WM6. In my case, i want to create an smartphone app send AT Command to the gsm modem of my HTC HD.
Apparently there's no port COM2 or COM9 open in the device (everytime i tried CreateFile there's error 55, i also checked in the active device registry, no COM2 or COM9), so i use RIL_Initialize and RIL_GetSerialPortHandle to get the port. The openning and writing steps works very well, however there's no data in return, seems that the modem doesn't respond.
Below is the code:
Code:
RIL_Initialize(1,
ResultCallback,
NotifyCallback,
dwNotifications,
dwParam,
&RilHandle);
HANDLE hCom = NULL;
char * xpos;
char rsltstr[5];
DWORD returnValue;
DWORD LAC;
DWORD CellId;
int bufpos;
DCB dcb;
COMMTIMEOUTS to;
DWORD nWritten;
DWORD event1;
DWORD nRead;
char outbuf[20], buf[256];
BYTE comdevcmd[2]= {0x84, 0x00};
GetSerialPortHandleResult = RIL_GetSerialPortHandle(RilHandle,&hCom);
if (FAILED(GetSerialPortHandleResult))
{
TCHAR szString[256];
wsprintf(szString, L"Error GetSerialPortHandle, result= %d",GetSerialPortHandleResult);
MessageBox(NULL, szString, L"Error", MB_OK | MB_ICONERROR);
return 0;
}
if (hCom==NULL || hCom==INVALID_HANDLE_VALUE)
{
TCHAR szBuf[80];
DWORD dw = GetLastError();
// get the most uptodate cells
_stprintf(szBuf, TEXT("CreateFile failed with error %d."), dw);
MessageBox(0, szBuf, TEXT("Error"), MB_OK);
hCom= NULL;
return -1;
}
if (!GetCommState(hCom, &dcb))
{
return -2;
}
dcb.BaudRate= CBR_115200;
dcb.ByteSize= 8;
dcb.fParity= false;
dcb.StopBits= ONESTOPBIT;
if (!SetCommState(hCom, &dcb))
{
return -3;
}
if (!EscapeCommFunction(hCom, SETDTR))
{
return -4;
}
if (!GetCommTimeouts(hCom, &to))
{
return -6;
}
to.ReadIntervalTimeout= 0;
to.ReadTotalTimeoutConstant= 200;
to.ReadTotalTimeoutMultiplier= 0;
to.WriteTotalTimeoutConstant= 20000;
to.WriteTotalTimeoutMultiplier= 0;
if (!SetCommTimeouts(hCom, &to))
{
return -7;
}
if (!SetCommMask(hCom, EV_RXCHAR))
{
return -8;
}
if (!DeviceIoControl (hCom,0xAAAA5679L, comdevcmd,sizeof(comdevcmd),0,0,0,0))
{
TCHAR szBuf[80];
DWORD dw = GetLastError();
// get the most uptodate cells
_stprintf(szBuf, TEXT("DeviceIoControl failed with error %d."), dw);
MessageBox(NULL,szBuf, TEXT("Error"), MB_OK);
return -9;
}
bufpos = 0;
strcpy(outbuf,"AT+creg=2\r");
if (!WriteFile(hCom, outbuf, strlen(outbuf), &nWritten, NULL))
{
return -10;
}
if (nWritten != strlen(outbuf))
{
return -11;
}
/*if (!WaitCommEvent(hCom, &event1, NULL)) // ALWAYS BLOCKED !!!
{
return -12;
}*/Sleep(500);
while(1)
{
if (!ReadFile(hCom, buf+bufpos, 256 - bufpos, &nRead, NULL))
{
return -13;
}
if (nRead == 0) // ALWAYS BREAKS !!!
break;
bufpos += nRead;
if (bufpos >= 256)
break;
}
strcpy(outbuf,"AT+creg?\r");
... // Continue to write and read
As i said above, there's no return error, just that the buffer read is empty...
Any ideas ?
Thanks!
I don't know why it always gets nRead = 0, all the other steps work very well, no error return ...
I saw several discussions about this, so i do believe that someone have tried once this dev in WM5 or 6...
Therefore could anyone please share some point ?
no one has an idea ?
There's something a little bit interesting that i found out directly in the memory.
There's a sequence of responses to AT Command writing in ASCII:
@HTCCSQ:3
@HTCCSQ:4
@HTCCSQ:2
+CREG: 1,"000C","9F60" (here we has current LAC + Cell ID)
+CREG: 1,"000C","9BC7" (another LAC + Cell ID, i think it's the previous one)
+COPS: 0,2,"20820",3 (inside the "" are MCC MNC)
@HTCCSQ:3 .... (there's plenty of @HTCCSQ: coming next )
Look like some kind of log of the querries of RIL driver to the modem (i'm not sure)
So i think the gsm modem is available for answering to the commands, just haven't figured out how to make a stream connection to it (in WM6).
Any ideas ?
Thanks.
TAPI
I heard somewhere that we can use TAPI to send some AT Command, my question is to know if we can send a custom command (for example AT+CCED) by using TAPI ?
hi,I met the same problem.Do you find the answer?
Thanks.
