I'm using C++ Builder and need a way to recieve 512 bytes of data through a RS232 connection without using ZComm.  I'm using 8 data, 1 stop, 1 start, no parity, com2, 9600 baud.  The data is from a DSP chip and is 8 bit hex.  I need a way to save the data to a char array.  I thought about using "inportb", but I'm not familiar with it.

you can't use inportb because you are programming with windows and you have to go through a virtual device driver

look at the delphi super page "http://sunsite.icm.edu.pl/delphi/" in the c++builder freeware section for a component called "comthred"
The zip file contain instruction on installing a component and the component works very well

You can also use the win32 api functions to do the serial comms if you want to write it yourself.

look at the question "serial port in windows" in the "windows programming" section of experts-exchange for source code on using the win32 api's for serial comms
