		Sender can sample reverse channel

config SYSTEM_ZMODEM_SENDATTN

config SYSTEM_ZMODEM_TIMESTAMPS

		Enable Zmodem debug output.  This debug is unrelated to the internal
		NuttX debug option; it does not use the SYSLOG channel but, instead,
		outputs debug information on stderr.  Obviously, enabling this

		use /dev/console to transfer files!

	bool "Dump buffers"
	default n
	depends on DEBUG_ZMODEM
	---help---
		Dump the contents of all incoming and outgoing buffers that are
		exchanged with the remote peer.
