Serial communication component C/C++ (and .NET) library (DLL) for serial port (RS-232.

RS-422, RS-485) communications.

Features of the Windows Serial Communications Library (WSC4C) include: Uses the standard Windows API to communicate with any device connected to a serial port (scale, modem, fingerprint scanner, printer servers, routers, etc).

Includes 34 functions plus modem control, ANSI emulation, ASCII/XMODEM/YMODEM protocols, hardware and software flow control (XON/XOFF, RTS/CTS, DTR/DSR).

State driven Xmodem and Ymodem on multiple ports simulatneously (up to 256 connections).

Is port re-entrant.

Is fully thread safe.

Can send Windows messages on completion of events (incoming character, etc.).

Supports virtual serial ports (usb to serial converter, bluetooth serial); multi-tasking, Supports any baudrate; can set baudrate, parity, stopbits; full buffered data transfer.

Includes multiple C/C++ and .NET example programs.

Can be used from GUI mode or console mode programs.

Includes 16-bit (WSC16.DLL) and 32-bit (WSC32.DLL) versions.

Supports most Windows C/C++ compilers (Microsoft (all versions Visual C++, C#, and .NET), Borland, Watcom, LCC-WIN32, etc.).

Can be used with Microsoft Foundation Class and Borland C++ Builder programs.

Does not depend on support libraries.

Makes calls to Windows API functions only.

Can be ordered with or without source code for the DLL.

Free technical support and updates for one year.

Online and print documentation.

Requires a Windows C/C++ compiler.

Supports Windows 95/98/Me/NT/2000/2003/XP.
