how to do a TAPI call

Hi
I want to make a call with my mda without using the RAS dialer. Direct access to the COM-ports does not work, as described in the document "Serial Communications". But that documents mentions that TAPI calls are possible with an xda.
It says:
"If you´ve establised a call, TAPI returns a handle for further data-i/o..."
Is there an example how to make a call using TAPI especially how to get that data-handle. And furthermore can I use that handle with WriteFile / ReadFile as I would use a handle to a COM-Port?

I did this for a terminal emulator I wrote. I pass a string to these functions which is COM1: for serial, TAPI for modem or RAS for TCPIP RAS.
I have simply copied some of my code here, work through it as if lpszPortName = "TAPI" and you should make sense of it. Once you have the port handle hPort which is returned by the Connected response of the TAPI call back function, then you can read and write as if that were a serial/file handle.
Cheers

Thanks for code posted. It is very helpful.
But I don't quite understand the logic how the "hPort" is created when receiveing a "CONNECTED" message callback.
Can you explain a little bit more?
- David

The handle to the port (hPort) is contained at the end of a variable length string (VARSTRING) that is returned from the call to LineGetID.
The fiddly thing about it is you give LineGetID a pointer to a VARSTRING called pvs and you have to fill in one of the member variables of pvs with the size allocated ( pvs->dwTotalSize ) to the variable length string.
Since I don't know how much to allocate to the VARSTRING, initially I just allocate enough memory from a sizeof(VARSTRING) result. Maybe you could just allocate a set size and not bother with the looping back, I think it is better to ask the system how much memory it wants as LineGetID may need more memory in later versions of the operating system.
Then you pass the VARSTRING with it's size stored in dwTotalSize to the function LineGetID.
The LineGetID function then fills in dwNeededSize with the size of the VARSTRING it needed to complete. That is why I loop back and re-allocate the VARSTRING to a new (bigger) size if NeededSize is greater than TotalSize.
Once the LineGetID function succeeds with a big enough VARSTRING then the Port Handle is at the end of the VARSTRING, as it is a variable length string you have to do maths to say the Port Handle is at the Address of the string PLUS the offset to the actural data wanted i.e. pvs + pvs->dwStringOffset The maths must be done with char* byte sizes and the final result is a handle, hence the casting HANDLE* on the final result.
Once the Port Handle is stored in hPort, the memory allocated to pvs is freed.
One other thing I noticed is that you can get multiple CONNECTED events, that is why I just exit the CONNECTED event if there is already a valid handle
I hope that makes sense.
Cheers
Paul

Do you have sample for the answering part?
thanks,
- David

No, sorry I have only ever written programs to dial out.

Hi,
I tried the sample code posted in this thread. It works only if I used
LineCallParams.dwBearerMode = LINEBEARERMODE_VOICE;
LineCallParams.dwMediaMode = LINEMEDIAMODE_INTERACTIVEVOICE;
combination. I got the RING message. However, the original:
LineCallParams.dwBearerMode = LINEBEARERMODE_VOICE;
LineCallParams.dwMediaMode = LINEMEDIAMODE_DATAMODEM;
didn't seem to work.
Do I miss something? (I think I have successfully killed the cprog.exe already)
Thanks,
- David

That means you are making a voice call.
So is the problem that you can not make a data(modem) type call ?
Check that you have data enabled on your SIM and also that under Settings -> Connections -> CSD Line Type it is set correctly. In the UK it is 9600 bps(v.32) and Non-tranparent, but I was told it is v110 is the states.
Let me know how you get on.

Is there any chance that somebody could compile this TAPI code as an object I could consume in C#? I have tried, but I am not even able to compile the example in C++... it's just not my world!
I would be eternally gratefull - and I bet a whole bunch of other guys who just want to quickly establish a data connection over GSM from C# (or VB?) would be also! It should have been in the phone.dll if you ask me!

compiled sample
Hey could somebody compile the tapi code for me in eVc++ or MFC ?? because i am really struggling. Plus what is toolbox.h i dont seem to have it ?? can somebody please help ??
thanks guys

This is an old post of mine, don't worry about Toolbox.h that was for the program I was writing and it has nothing to do with Tapi.
This sample code was not meant to compile, after you you won't have function VTPrint but I hope you can guess that just shows text. It was just posted to demonstate the order of functions needed to get a modem connection.
I built all this Tapi code into a DLL and I have it all presented with the eVC 3.0 build files in this post, this code will compile as presented and is just a zip of all the project files of a single sample application.

Have a look there.

during a data call when using TAPI can u make some kind of AT command request ??? and retrieve the data from that answer ??? And do i need some TAPI app on the remote unit to send the data back ?
i am trying to access a remote unit ( GPS RX and GSM TX )

I don't really understand your question that well.
But AT commands have nothing to do with TAPI, so any question saying can TAPI send an AT command for etc -- The answer must be no.
All TAPI does is gives a Handle that can be used with ReadFile and WriteFile for receiving and sending data over the modem.
So TAPI will dial a number and establish a DataModem connection, then on Connect it can provide the handle for you to direct read/write requests to. Once the link is established you just treat the handle as if it was a file handle returned from a CreateFile command.
As said earlier all this has nothing to do with AT commands.

During a data call should ic onnect via COM 1 or COM 9 if i'm using TAPI ?? Would you have any sample code i could have a look at ? I'm a bit lost at the moment .... with LineGetID too ...

you can't use COM2 or COM9 via TAPI cause COM2 and COM9 masked by RIL
about lineGetID look http://forum.xda-developers.com/viewtopic.php?t=9761

ok thanks - so if i cant use COM1 or COM9 in this case then i'm guessing that i shall pass a string (lpszPortName) just like the example on this post.
Code:
// Open the serial port.
hPort = CreateFile (lpszPortName, // Pointer to the name of the port
GENERIC_READ | GENERIC_WRITE,
// Access (read-write) mode
0, // Share mode
NULL, // Pointer to the security attribute
OPEN_EXISTING,// How to open the serial port
0, // Port attributes
NULL); // Handle to port with attribute
// to copy
But what should the string lpszPortName be initialized to ? Or am i totally wrong ?[/quote]

L"COM9:" for COM9
but not with TAPI
with TAPI you have not open any COM-ports
you must use lineGetID

Code:

{

return FALSE;
}
Are the COM and Timeout settings necessary when using TAPI ? because i am getting an error message at the !setCommState function.
I use lineGetID to retrieve the Handle to the Comm then i try to use readFile but the operation is unsuccesful.
Anyhelp from out there ? thanks.

Are you sure that you call lineGetID only after connection?

Maybe you are right. I just do lineMakeCall then do lineGetId without waiting for a LINECALLSTATE_CONNECTED message.
I think its because i have troubles implementing the lineCallBackFunc() i dont understand the parameters that need to be passed to it.
Code:
void CALLBACK lineCallbackFunc(
DWORD dwDevice, DWORD dwMsg, DWORD dwCallbackInstance,
DWORD dwParam1, DWORD dwParam2, DWORD dwParam3)
{
Anyhelp for this ?? Cheers.

Hi ft1860!
I don't think you can do it that way, although I never tried it. You should check out power management API:
http://msdn.microsoft.com/library/d...pplicationsToTurnSmartphoneBacklightOffOn.asp
This example is for smartphones but should work on a PPC just as well.
P.S.:
Error 161 is "The specified path is invalid" so you should check the device name (no idea what that might be).

hi levenum
Thanks your comment,but according to this document
http://windowssdk.msdn.microsoft.co...r/base/ioctl_video_set_display_brightness.asp
It say we can set the current AC and DC backlight levels by invoke DeviceIoControl with IOCTL_VIDEO_SET_DISPLAY_BRIGHTNESS parameter.
So first I must create a handle of LCD,but I cann't open it successfully,
why?

oh,I make a mistake
IOCTL_VIDEO_SET_DISPLAY_BRIGHTNESS is Win32 function.
On smart device,I should use SetPowerRequirement to set the backlight.
But when I invoke SetPowerRequirement on my Universal with D0 or D4,it say success ,but nothing happened.

maybe you have to access backlight by BKL1: device.
CreateFile(L"BKL1:", ....
or write the brightness value into registry.. that works for sure.

I'll try it.

It seem that SetPowerRequirement D0-D4 just Open or close backlight,
but what I want is adjust the backlight's brightness.

It almost work.
It works fine on my Universal,but it doesn't work on my x50v with WM5.
I should not debug it on my x50v,there is so many bugs in Dell's WM5 update.

WM6 - how to Query WLAN "connection" status

I am desperately trying to work around some unknown problem caused by our NDIS IM driver on WM6 and HTC TyTn ( TyTn at least, but most likely other devices as well ). I started some other threads regarding different facets of this problem, and no help is coming. Now I am just trying to work around it.
in short the problem is when power events happen the WLAN will never connect.
The work around is programmatically open the control panel with STControlPanel class and press the down button 1 time then the f1 key ( right dash ). This "presses connect" on the last configured access point. This works around my problem, however, I need to detect when the access point has connected. There is a "connecting" and "connected" message for the access point in this control panel dialog ( control panel # 17 ).
My Question: Is there some way to get this text "connecting" or "connected" from the control panel #17?
I have tried wzc, ndisuio, winsock, and other "non control panel" ways to detect connected state, but the IM problem fools all these methods. The only thing I have ever seen that successfully shows when the problem has occurred is the "connecting"/"connected" status in the control panel 17.
Please Help Someone.
p.s. If I can get this worked around, we sell a commercial grade ndis intermediate driver toolkit letting you easily write plugins without any of the hard driver details. We have redirectors, transparent proxy, tunnelers, virtual adapters, lots of good stuff. Also the same plugin will work on all windows desktop platforms vista - 98, WM5/6 and CE and also linux and solaris...

[IDEA] Xbox360 Controller for Android

Possible to make the Xbox360 controller connect to your Android phone ?
there's alot of software for both Mac and Windows letting you connect it to your computer, so without too much research i wondered if there is a possibility to port one of those apps over to android and use the controller for emulators and games.
there must be some open-source apps for win/osx out there i think so if any dev would have a look at it, for me to read those codes would be the same as to try to teach me greek..
just an idea, but if there's anyone that could make something out of this i think there will be alot of people wanting to use it
kinda like the SNES controller the streak's got, only wireless instead.. haha

Xbox 360 controllers aren't bluetooth
Sent from my HTC Droid Incredible. This Droid Does More.

its not just software to allow an Xbox controller to be connected to a PC, unless you're talking about the wired version, you need the reciever.
Like generamerica says, Xbox controllers aren't BT. PS3 ones are, but the bluetooth it uses is slightly different than normal and if i recall there have been issues in the past trying to get it to connect, no idea where that project has gone since then.
The only controller that can work with android from the big 3 atm is the wiimote, and even then you have to be running the stack from AOSP instead of the sense stack.

You got a lot of Bluetooth receivers !
It's possible !

!!!!!!! lo voglioooo contropper per android...cosi gioco a game psx gba

why not ps3 controller?

Yeah 360 would be impracticle if not impossible as you would have to either use a wired controller or have a wireless adapter for it to work. All of which means more stuff to lug around with an already large controller.
It would be cool to get the ps3 controller working on android but the controllerr is fairly big to carry with your phone.
Btw, the ps3 controller works great on windows. I use it with my netbook to play games in between classes. It connects to my normal Bluetooth receiver without any issues using a custom driver and software to pair the devices.
The only problem I can see coming from getting a ps3 controller working on android would be that once you pair the controller to the receiver you can no longer use it with any other devices unless you unpaid and uninstall driver to original. This is how it is with the controller on windows and most people use 2 Bluetooth receivers to deal with the problem.
Regardless of how practicle it would be to carry a ps3 or Xbox controller around with your phone it would be sweet to have working especially to get some of the other bluetooth controllers that are out there working. I have seen Asus controllers that are Bluetooth and have all the same buttons as ps3 controllers but they fold up and are a lot smaller and easy to carry around.
And a Bluetooth controller would be great for us who do not have enough hardware keys to play games with - no hardware keyboard.
Sent from my HTC Hero CDMA using XDA App

Its hardly impractical, if you was chilling at work on a break and you and a friend wanted a game of street fighter on Tiger mame or something then i think linking two xbox pads to your phone and having a few round would be superb, I would avoid even bothering with wireless with the xbox pad because it's not bluetooth and the ps3 is problematic for most devices using sense (which means half of them) so it's just the wired xbox pad, a port or a fresh app which can link the onscreen buttons to games or emulators to the digital buttons would be fantastic.
Dev's would pick up on this and would probably develop around them if it became successful enough, I think it's a good idea, the reason i say that is because the onscreen keyboards for the devices out now have some achillies heel's on them, first one is the fact that it's touchscreen and it's just not the same as a pad, the second is there is only ever going to be one player per device the likes of street fighter 2 turbo and king of fighters were ment to be played with two players, not to mention the amount of other game types which would be played better on a pad other than touchscreen.
In an ideal world it would be a cable to your tv and a cable to your pad, run a game on your phone and play it on your tv with your xbox pad wired.
I know it can be done, might look into doing it myself, usb can be split too, analogue could come later, hmmmmm.

There is an actual implementation of Xbox360 controler for the Elocity A7 tablet,

But idk if it could be adapted to other android devices since it seems to need an usb port support.

Yeah, in order to use the wired controller, you would need USB Host mode drivers, which at the moment not a lot of Android phones have (yet). At least, not to my knowledge anyway. Then you would need some sort of adapter to go from Mini/Micro USB (depending on which phone you have) to regular USB.

well I've seen some articles where people have some sort of adapter that turnes mini/micro usb into a dual input for (mouse / keyboard) so I guess two controllers shouldn't be that much further off... it's a matter of who has the knowledge and can implement it... unfortunately, it isn't me =( heh

But for the devices with usb ports how would one go about getting the required support in their rom?
When you plug the 360 controller in nothing happens.. I would like to know what files I may need to push to my android device that HAS full usb ports.

Get a micro usb to female usb cable, plug in the wireless adapter. Your device has to be running Android 4.0 to work, but it does work flawlessly. You then have to go to market and download a free app that allows you to configure the buttons on the controller....then you're all set. There are also a few games that are already set in options to run third party controllers as well. I'm planning on doing this as soon as we get some type on ICS love from any direction for the SGS2 SGH-T989, so. I hooked this setting up on a customers Galaxy Tab, so. Awesome...

This doesn't have to do with the xbox controller, but On my old itouch, I could use a wii controller to play games on a nes emulator. If it's possible with ios, then it has to be with android.

Well, maybe it's possible to make Android using pads already connected to PC? I have Xbox 360 pad with PC receiver and I am wondering if it's actually possible to connect that controller to Android device (mine is HTC Desire Z).
I'm afraid that there can be some input lag but maybe that can be done?

Plausible and an achievable concept... is it worth it? Lol?
This got me thinking.
I dont know why anyone would want to do this now a days but it is very possible.
Back in 2007 remotejoy came out on the psp-1001 Phat.
Basically the concept is simple you would put a couple of .prx files on the memory stick pro duo in the root directory in a folder named plugins. And set up a windows drivers and a small application I think. I'm not 100% about that but seems logical.
Then interface the psp with the pc via USB but before interfacing, you would have to go into the vsh menu which you would hit a button combo and a text overlay would appear over the xmb in the top left hand corner. You could then select what plugin you wanted to load. Then you would load up the prx's and plug in your controller and USB type B from the psp to the pc. It would detect it though libusb and then you simply execute remotejoy.exe "I think" don't quote me on any of this. It was a long time ago....
Then you would literally be able to play your game on your monitor or on a flat screen like me. Via dvi output from an ant 1600xt graphics card in crossfire. And my 10000 pound Sony professional 42 inch $4000 plasma..... and then thru remotejoy gui you could go to controllers and basically use any analog controller that there were drivers for...... Man things have really changed in 13 years!!!!.... Jeez.
These plugins could add all kinds of extra features. Fps counter, background music player, an ir yeah infrared.... lol irmanager a badass file explorer with every feature you could ever imagine, well there was an irshell .prx, and a psx one called pops before Sony ever even released it.....
Sound familiar? Should, first there was xposed framework, now we have magisk plugins with support for xposed modules....
With that being said this is very possible and a feasible feat. (Not that anyone should take it on).....
It was coded under unix. So same kernel we use on androids..... It could be forked/updated/shimed/referenced/converted/reverse engineer to remotejoy magisk plugin but it's old code.
I think the last time it was updated was in 09 when I graduated high school.... so someone way more talented then me could possibly modify and retrofit or port to android using adb and USB debugging on a rooted android.
But this is not my area of expertise ports aren't my bag, man.
It would be a huge undertaking.
For controller support it would use socks. TCP specifically.
I didn't dig into it too much because well everyone now a days has smart share or screen mirroring and bluetooth xbox one s controllers and 4k TV's......
Just wanted to say it it a very plausible and achievable project.
Sorry to dig up an old thread. I have the original source code somewhere.
Here's an excerpt for controller support and mapping via universal serial ports it's in raw.
