serial (RS232) question

[pharma]

byte xfr[3];
xfr[0]= AA;
WriteFile( h_Com, &xfr, 1, &BytesWrtn, NULL);

If this sends only one element to rs232 port, how to send
a whole binary file to serial port using same function?.

If you have no protocol-library, you have to open your file for reading and send each Byte, close the file, etc...
