Help sending hex to serial port as HEx

Question

I am trying to send a intel hex file to serial port as hex. When I send it the hex shows up in text window and the hex window shows the hex of what i am trying to send as if it were a text string.  For example when I try to send "FF" the text window shows "FF" and the hex window shows "46 46"  I need a way to Send FF so that the hex window actually shows "FF"  I am using VB2008

Thanks,
