CAN tutorial

I believe I have figured out the issue here, and it is totally 100% human error if so. I believe that the issue arose from the fact that I forgot that DB9 female is reverse on its pin numbering from DB9 male... This would explain why it was a solid yellow LED (jag was receiving comms from the computer, because pin 3 is the same on both male and female, and is Tx), but was not appearing on BDC-comm (Rx was not wired in at all, rather, it was the DTR pin) it might also explain why it could not change its number, it must require some sort of handshaking to do so. Again, this is theory, and will not be tested until Thursday, but I'm willing to make a solid bet that that's the issue here. I'm sorry that I sort of wasted your time.
