Thank you chofrock - I managed to connect my Galileo using the audio jack and seeing the boot process on my PC. The reason for the shield though is old RS-232 equipment is +/- 12 volts and could fry the board if connected without the shield.
I thought the shield was also a UART connection. I will test your idea though by writing a short sketch to open a serial connection and print "Hello World" and see if the old terminal gets it….
Thank you AlexT at Intel! I will also try your approach and modify the grub.conf file and change the device and see if I can get a Hello World emitted. Unless I have time later tonight, I will be traveling for the next few days but will follow up on this post with my findings on both approaches.
I appreciate the help very much!
thank you,
John
