@kennethlimcp, yes, I am doing both the begin and the print.
The problem is that at the OS level the serial ports are not being initialized. When you go into the Device manager in Windows it says there are no serial ports available. If you go into CoolTerm it says there are no devices available. If you go into PuTTY it says there are no devices available. This problem didn’t start until the phantom .26 code started showing up sometime after lunch.
In fact, I had hooked up a uBlox M6 to my Argon and it was spitting out GPS data with no problem, and I was serial monitoring it with no problem. After lunch I wanted to move the uBlox to the Xenon and mesh it over to the Argon, which would then upload it to the Internet. That’s when I started seeing the .26 code become an option and things started breaking. Same exact code that worked before lunch broke horribly since the serial ports would not initialize. This happened with Argons, Xenons, and multiple laptops.
