Do you have information from the makers of the balance as to what gets sent or received via the serial (i.e. COM) port?<br />
<br />
If so, you just open the COM port using CreatFile(), read the data with ReadFile(), and write with WriteFile().<br />

I have done it like this.<br />
I have attached a CString member variable to the CEdit control<br />
by going to Class Wizard and selecting the member variables tab<br />
unsigned char * rx_buffer = new unsigned char[number_of_chars+1];<br />
Port.Read(number_of_chars+<wbr />1,rx_buffe<wbr />r); &nbsp;//read the port<br />
buffer[0]=__toascii(rx_buf<wbr />fer[0]);<br />
m_kelvin_temp = buffer[0];<br />
for(n=1;n&lt;8;n++)<br />
{<br />
&nbsp; &nbsp; buffer[n]=__toascii(rx_buf<wbr />fer[n]);<br />
&nbsp; &nbsp; m_kelvin_temp +=buffer[n];<br />
}
