A worker is needed to write a C++ class and a demo application. The class will handle transmitting and receiving packets of characters through the serial port. Since this is for a legacy application, you would required to use the DJGPP compiler to ensure code/library compatibility. Please see the attachment for details.
I have written serial port handling code several times with C++ and C# on different platforms and compiled them with different compilers even for embedded platforms. I can help you.
