-EIO. Except for traditional RTOS skins like VxWorks, VRTX and so on
which have their own error list, we tend to normalize on POSIX error
codes in all other parts of the codebase.
Regarding the EIO issue, it looks like a transmission error has been
detected on the read-side by the 16650A driver. Jan will likely tell you
more when time allows.

Yes, the documentation link on our website is a good starting point. For
the particular EIO issue on the serial driver, I'm not sure there is a
lot more explanations than the one above, though.
