Easy to use professional serial communication C++ class library for Windows. COMM-DRV++ allows you to accomplish your serial communication task literally in minutes after installation. We have encapsulated general communication functions into easy to understand methods that are applicable to real world applications. The following example is a complete working Windows application that calls another computer and transfers a file to it. Could it be any simpler? #include "CCdrvPPPort.h" main() { CCdrvPPPort Port; if (!Port.OpenPort(1)) if (!ModemDial("2815551212") if (!Port.SendFileZmodem(FileXferDialogFlagOn ,"Myfile.txt") cout << "File transferred successfully"; Port.ClosePort(); } Major Features: *COMM-DRV++ is compatible with Windows XP, Windows ME, Windows 2000, Windows 98, and Windows 95. *COMM-DRV++ supports the Microsoft Visual C++ and Borland C++ compilers. *COMM-DRV++ supports all serial ports that have a Windows driver.
