I have done serial port RS-232 connection in C++ using 16-bit compiler (I was using Turbo C++ IDE). It included header file bios.h which contain all the required functions for reading values from the port. Now I want to read value from serial port using C++ 32-bit Mingw compiler. I am using Dev CPP as my IDE. Here I could not find bios.h. Are there any special header files available for this purpose in Mingw? I am using 32-bit compiler now because in my college project I got to use Exception handling which I guess is not supported in Turbo C. Please help me out.

Half duplex serial communication needs at a minimum two wires, signal ground and the data line. Full duplex serial communication needs at a minimum three wires, signal ground, transmit data line, and receive data line. The RS232 specification governs the physical and electrical characteristics of serial communications.
