Serial(RS232) programming under WinNT 4.0
Posted on 2003-11-10
I need a simple self-loop test Visual 6.0 C++ program on a 9-pin D connector where pin 2 & 3 are shorted together. I have done similar thing before under Win 95/98 where outport()/inport() functions are used. But to what I understand I can't do so in WInNT where I cannot access the hardware directly. Pls help to provide some sample codes/web links so that I can jump start my project. I 'm not familiar with MFC thus need some help here ... Thanks.
