Windows Console write or flush may fail (throwing WindowsError, a subclass of OSError) if the data written can't be displayed. This may be the case if the serial port is producing garbage bytes. Ignore the error, in the hope that the serial port may "come good" and write non-garbage later.

# esp-idf serial output monitor tool. Does some helpful things:
|
|
# - Looks up hex addresses in ELF file with addr2line
|
|
# - Reset ESP32 via serial RTS line (Ctrl-T Ctrl-R)
|
|
# - Run flash build target to rebuild and flash entire project (Ctrl-T Ctrl-F)
|
|
# - Run app-flash build target to rebuild and flash app only (Ctrl-T Ctrl-A)
|
|
# - If gdbstub output is detected, gdb is automatically loaded
