HS Win32COM C Source Library 1.0

HS Win32COM is a useful and reliable software library in C which allows a calling user application to access serial communication ports (COM devices) user 32 bit MS Windows operating system. It allow to transmit data, asynchronously receive data and control and process line signals (RTS. DTR). At lower level the OS may map COM devices to RS232, USB, Infra-red (IRDA) or other hardware.
HS COM library provides a convenient "packaging" to standard Win32 API by exposing only a few simple API services to a calling application.
Main features:
- Configures serial communications COM device
- (Baud rate, data length, parity, stop bits, flow control)
- Transmits and Receives data to and from COM port with a non-blocking calls
- Performs extended functions on COM device: DTR and RTS line control
