COMM: Demonstrates the Communications APIs COMM demonstrates the basics of using the Microsoft(R) Win32(R) communications application programming interfaces (APIs) while maintaining a common code base with Microsoft Windows(R) 16-bit code. The COMM program performs communications using the Windows OpenFile, ReadFile, SetCommState, SetCommMask, WaitCommEvent, WriteFile, and CloseFile functions. It creates a background thread to watch for COMM receiver events, and posts a notification message to the main terminal window. Foreground character processing is written to the communications port. Simple TTY character translation is performed, and a screen buffer is implemented for use as the input/output (I/O) window. Overlapped file I/O techniques are also demonstrated. When using COMM, the baud rate, data bits, stop bits, parity, port, RTS/CTS (Request to Send/Clear to Send) handshaking, DTR/DSR (Data Terminal Ready/Data Set Ready) handshaking, and XON/XOFF handshaking can be changed under the Settings menu. Once the communications settings have been selected, you can use the Action menu to connect to or disconnect from the TTY program. COMM is a Microsoft Win32 Software Development Kit (SDK) sample. It was built with Microsoft Visual C++(TM) version 2.1, the 32-bit development system for Microsoft Windows, Windows 95, and Windows NT(TM), and was tested under Windows 95 and Windows NT version 3.51.

After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
