serial port lines RTS, DTR * Full range of COM port baud rates: 110 to 256000 * Setting number of data bits, stop bits and parity * Hardware (RTS/CTS) , software XON/XOFF or NONE flow control Internally, HS COM implements receive and transmit buffer queues, serial communication receive and transmit threads and uses asynchronous overlapped IO. This makes it easy for applications to add serial communication support by using HS COM C Source Library
