Com komunikace v C – C / C++ – Fórum – Programujte.com

Zdravim,
delam na jednom programu v C, ve kterem potrebuji posilat AT prikazy pres com port na mobil. hledal jsem cely den ale nic nenasel. Je na to nejaka knihovna, nebo pres nejaky terminal ale jak do nej dostat prikazy z programu? Prosim vas o pomoc.
Diky moc

jaky system?


ve win je treba tady jeden prospevek ... http://www.control.com/1026187785/index_html

To KIIV : jj je to windows... zalibil se mi tam tenhle kod

#include <bios.h>

#include <conio.h>



#define COM1       0

#define DATA_READY 0x100

#define SETTINGS ( 0x80 | 0x02 | 0x00 | 0x00)



int main(void)

{



   int in, out, status;

   bioscom(0, SETTINGS, COM1); /*initialize the port*/

   cprintf("Data sent to you:  ");



   while (1)

   {



      status = bioscom(3, 0, COM1); /*wait until get a data*/

      if (status & DATA_READY)

           if ((out = bioscom(2, 0, COM1) & 0x7F) != 0)  /*input a data*/

              putch(out);



           if (kbhit())

           {

              if ((in = getch()) == 27)   /* ASCII of Esc*/

                 break;



              bioscom(1, in, COM1);   /*output a data*/

           }



   }



   return 0;



}

To Bedla : Jednoduchu a to tak ze ho explicitne prevedies na cislo:

char c = 'A';

int asciiNum = (int)c; 

To Bedla : to ze se ti zalibil neznamena ze bude fachat :)
spis sem mel na mysli tento

        HANDLE   hCom;

 COMMTIMEOUTS  lpTo;

 COMMCONFIG  lpCC;



        char str_com[10];

 unsigned short  no_com = 0;





 sprintf( str_com, "\\\\.\\COM%d\0", no_com+1);

 hCom = CreateFile(str_com,GENERIC_READ|GENERIC_WRITE,0,NULL,

        OPEN_EXISTING,FILE_FLAG_OVERLAPPED,NULL);

 GetCommState( hCom, &lpCC.dcb);



 /* Initialisation des parametres par defaut */

 lpCC.dcb.BaudRate = CBR_9600;

 lpCC.dcb.ByteSize = 8;

 lpCC.dcb.StopBits = ONESTOPBIT;

 lpCC.dcb.Parity = NOPARITY;



 lpCC.dcb.fDtrControl = DTR_CONTROL_DISABLE;

 lpCC.dcb.fRtsControl = RTS_CONTROL_DISABLE;

 SetCommState( hCom, &lpCC.dcb );



 GetCommTimeouts(hCom,&lpTo);

 lpTo.ReadIntervalTimeout = 0;

 lpTo.ReadTotalTimeoutMultiplier = 10;

 lpTo.ReadTotalTimeoutConstant = 10;

 lpTo.WriteTotalTimeoutMultiplier = 10;

 lpTo.WriteTotalTimeoutConstant = 100;

 SetCommTimeouts(hCom,&lpTo);



 SetupComm(hCom,2048,2048);



To close the port :



        CloseHandle(hCom);



To monitor communications events :





       SetCommMask(hCom, dwEvtMask );



dwEvtMask is logical or with : 

EV_BREAK, EV_CTS, EV_DSR, EV_ERR, EV_RING, EV_RLSD , EV_RXCHAR, EV_RXFLAG, EV_TXEMPTY values



 and used WaitCommEvent function



  BOOL WaitCommEvent(

     HANDLE hFile,

     LPDWORD lpEvtMask,

     LPOVERLAPPED lpOverlapped

   );

diky vsem za odpovedi
To KIIV : no ten jsem zkousel ale hazelo to chyby,, ale kdyz na to koukam tak jsem tam nemel include. co vsechno musim naincludovat aby to jelo? takhle slozity program delam poprve, tak narazim na spoustu problemu

To Bedla : mam pocit ze hlavni bude asi neco jako <windows.h> primo to CreateFile je v <winbase.h> ale to je tak jak tak includovano z windows.h ...

asi vypadam jako uplna lama, ale v Turbo C windows.h nemam, a kdyz si tam nakopiruju *.h soubory z Microsoft SDKs tak nefunguji a vypisuje strasne moc chyb

no to v turbo urcite nepude... turbo je snad jeste pro dos... kazdopadne v jakymkoliv systemu jako NT, XP, a novejsi se dosem na porty primo nedostanes...
to chce testnout aspon devcpp nebo tak
