Hello: I like to dial a phone number in C++, is it possible?? thanks Maurice Hi: I have two modems: one internal connected to com3, and one usb external connected to com4 (information from Device Manager) I tried the following: #include "stdio.h" #include "bios.h" void main() { int x; FILE* comport; if(!(comport=fopen("COM3:","w+"))) perror("COM3 not open."); else { fputs("ATDT01555444333\n",comport); } if(comport) fclose(comport); } I compiled and the response is: COM3 not open.: No such file or directory (I tried both "com3" and "com3:" ), the same thing happens to com4 any idea?? thanks Maurice Back to top Bob Gonder Guest Posted: Sun Sep 10, 2006 7:51 pm    Post subject: Re: dialing a phone number Morosh wrote: Quote: I have two modems: one internal connected to com3, and one usb external connected to com4 if(!(comport=fopen("COM3:","w+"))) perror("COM3 not open."); COM3 not open.: No such file or directory (I tried both "com3" and "com3:" ), the same thing happens to com4 "COM3" is correct You might try using HANDLE h; h = CreateFile( "COM3", GENERIC_WRITE, 0, 0, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, 0 ); if( h != INVALID_HANDLE_VALUE ) { DWORD byteswritten; WriteFile( h,"ATDT01555444333\r", sizeof("ATDT01555444333\r")-1, &byteswritten, 0 ) /* also notice the change to \r */ CloseHandle( h ); }else{ //handle the error }; Back to top Morosh Guest Posted: Tue Sep 12, 2006 8:10 am    Post subject: Re: dialing a phone number "Bob Gonder" <notbg (AT) notmindspring (DOT) invalid> wrote in message news:in88g21pd7ivvo44c2no7a54kl7ii2sic0 (AT) 4ax (DOT) com...

I tried "io.h", it didn't work. I use always the free command line compiler. that's what I've tried: ******************************************* #include "stdio.h" #include "io.h" void main() { HANDLE h; h = CreateFile( "COM3", GENERIC_WRITE, 0, 0, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, 0 ); if( h != INVALID_HANDLE_VALUE ) { DWORD byteswritten; WriteFile( h,"ATDT01555444333\r", sizeof("ATDT01555444333\r")-1, &byteswritten, 0 ) /* also notice the change to \r */ CloseHandle( h ); }else{ //handle the error }; } Thanks Maurice Back to top Bob Gonder Guest Posted: Tue Sep 12, 2006 10:36 pm    Post subject: Re: dialing a phone number Morosh wrote: Quote: But which header file should be included in the beginning? We are in the .nativeapi group. Those functions are native Windows API functions. The vast majority of Windows functions are available by including windows.h. #include <windows.h> The headers for those that are not included by windows.h may be found by looking at the documentation for the functions. MSDN is esspecially good at that. http://msdn.microsoft.com/library/ Back to top Maurice Guest Posted: Thu Sep 14, 2006 3:12 pm    Post subject: Re: dialing a phone number "Bob Gonder" <notbg (AT) notmindspring (DOT) invalid> wrote in message news:5hrdg2djn4a8onsagqjb7nr2mnjuqqkneq (AT) 4ax (DOT) com...

Any idea??? Thanks again Maurice Back to top Bob Gonder Guest Posted: Thu Sep 14, 2006 10:02 pm    Post subject: Re: dialing a phone number Maurice wrote: Quote: Now, if you had time, I like to read the modem status to know if the ligne is busy or not. Any idea??? After WriteFile() do a ReadFile() to read the response. You would probably want to read single chars and build up a response out of them because you don't know the size of the response ahead of time.
