What kind of serial device are you talking through?
If you want an old-fashioned serial port, you'll need one of these:

If you're talking with something lower voltage (say, 5V) then you'll need a TTL serial adaptor.

Once you have that figured out, the actual talking out the serial port is relatively straightforward. All serial devices will appear in the /dev directory, and a USB serial device like one of the ones above will most likely be /dev/ttyUSB0, or /dev/ttyACM0.
Once you have that figured out, you want to use the functions in <termios.h> (man termios) to set the options such as baudrate, parity, stop bits, flow control, etc.

Dear Lord. Let me find my Tomato post and get you what you need to order to open this up…

Send the original firmware when you'll repair the firmware. Once you confirm it works, you can just repeat the same process and send a different firmware of your choice.
So, according to my self past, you'll need those :
Driver is somewhere in the post, and I was using Windows 10 at the time. Take your time to read the story, don't panic, and calmly order those two items.
No key, no SSH access. That’s the great (and terrible in this case) design of Secure Shell.
I assume this is on a Pi? Go on Amazon or any online store and buy a serial cable like this and connect only the Rx/Tx wires to the Pi.
I usually buy them for $10 or less so you can look around and show me the link if you want me to verify it will work with a Pi.
The pocket chip worked fine or at least got to the boot messages before? Which image did you flash? Guessing you have no way to connect to the serial pins on the device? You'd need something like this to do that: https://smile.amazon.com/ADAFRUIT-INDUSTRIES-954-SERIAL-RASPBERRY/dp/B00DJUHGHI/ref=sr_1_13?keywords=usb+serial+cable&qid=1551373844&s=electronics&sr=1-13. That's the easiest way by far to tell what's going on at the start. If you have or can borrow an RPi or similar, I think you should be able to rig something board to board too.
If it's not showing anything but not in FEL mode, I'm guessing it can't read the u-boot bootloader from the on board flash memory for some reason. If that's the case it might be able to boot from a USB stick properly set up since it should scan for one having failed to boot from NAND. I'll see if I can whip something up if you have a USB stick to use.
How are you flashing? Linux VM from Windows? I'm not sure what the Thrug script is, I've always just used the scripts from the CHIP flash archive (https://archive.org/details/C.h.i.p.FlashCollection). Do you have a link to the Thrug script?
I am in NorCal. Thanks for the offer. Do you know if this will work for flashing? https://www.amazon.com/ADAFRUIT-INDUSTRIES-954-SERIAL-RASPBERRY/dp/B00DJUHGHI
