Greetings! I am writing an application with a touch pad connected to a com port (Serial Port RS232) in C++. The thing is, I would like an endless loop (inerrupted by kbhit), but I would like to know when signals come through start reading, not like now, I am constantly reading buffer from Com prot and if there are non zero values, we have transfer. Souch function works, but i can believe there isn't any function out there which would tell me i got transfer? I tried WaitCommEnvet and nothing happnes... Current stage: <code> while(1) { memset(Read_Buffer, 0, 4096); ReadFile(hCom, Read_Buffer, 1, &dwBytesRead, NULL); if (Read_Buffer[0] != 0) printf("Com event!\n"); if (kbhit()) break; } </code> I would like something like this: <code> while (1) { If (WaitCommEvent(hCom, 0, 0)) { printf("Com event!\n"); memset(Read_Buffer, 0, 4096); ReadFile(hCom, Read_Buffer, 4096, &dwBytesRead, NULL); } if (kbhit()) break; } </code> Thank you in advance!
