bool "Using espressif VFS"
default y
help
Enable this option, espressif VFS can be used. Users can use APIs like "open", "read", "write"
and so on to operate I/O device which is registered.
config SUPPRESS_SELECT_DEBUG_OUTPUT
bool "Suppress select() related debug outputs"
default y
depends on USING_ESP_VFS
help
Select() related functions might produce an unconveniently lot of
debug outputs when one sets the default log level to DEBUG or higher.

help
Disabling this option can save memory when the support for termios.h is not required.
