    Lightbulb RS232 serial port library for Linux and Windows

    If you intend to write a GPL-licensed, opensource and multiplatform program in C or C++ and you want to use the serial port, look here:

    RS-232 for Linux and WIN32

    With this library, you can use GCC on Linux and MinGW on windows to access the serial
    port without the need to make any changes in your sourcecode.

    Regards.

    Put the two files in the directory where your other C files are.
    Put the following define in the headerfile of the module from
    where you want to use the RS-232 functions:

    #include "rs232.h"

    Don't forget to tell your compiler that it has to compile and link
    the rs232.c file. For example:

    gcc main.c rs232.c -o myprogramname

    You can use this library for USB-devices as well in case your USB-device uses a FTDI-chip
    for USB-connection in combination with a VCP-driver (Virtual ComPort).
    Linux has this USB-VCP-driver already built-in. For windows you need to download
    a free driver from the FTDI website.

    For more info about VCP-drivers for USB-devices, visit:

    Virtual COM Port Drivers

    Virtual COM port (VCP) drivers cause the USB device to appear as an additional COM port available to the PC. Application software can access the USB device in the same way as it would access a standard COM port.

    There is no difference with a serial port because the VCP-drivers emulates a serial port.
    Except for that you have to open /dev/ttyUSB0 instead of /dev/ttyS0.

    Virtual COM port (VCP) drivers cause the USB device to appear as an additional COM port available to the PC.
    Application software can access the USB device in the same way as it would access a standard COM port.
