config SYSTEM_ZMODEM
	bool "Zmodem commands"
	default n
	---help---
		This selection enables the 'sz' and 'rz' NSH commands.

if SYSTEM_ZMODEM

config SYSTEM_ZMODEM_DEVNAME
	string "Default Zmodem device"
	default "/dev/console"
	---help--
		The default device used by the Zmodem commands if the -d option is
		not provided on the sz or rz command line.  Default:  "/dev/console".

config SYSTEM_ZMODEM_RCVBUFSIZE
	int "Receive buffer size"
	default 512
	---help---
		The size of one buffer used to read data from the remote peer.

config SYSTEM_ZMODEM_PKTBUFSIZE
	int "Maximum packet size"
	default 512
	---help---
		Data may be received in gulps of varying size and alignment.
		Received packets data is properly packed into a packet buffer of
		this size.

config SYSTEM_ZMODEM_SNDBUFSIZE
	int "Send buffer size"
	default 512
	---help---
		The size of one transmit buffer used for composing messages sent to
		the remote peer.

config SYSTEM_ZMODEM_MOUNTPOINT
	string "Zmodem sandbox"
	default "/tmp"
	---help---
		Absolute pathes in received file names are not accepted.  This
		configuration value must be set to provide the path to the file
		storage directory (such as a mountpoint directory).

		Names of file send by the sz commond, on the other hand, must be
		absolute paths beginning with '/'.

config SYSTEM_ZMODEM_RCVSAMPLE
	bool "Reverse channel"
	default n
	---help---
		Local sender can sample reverse channel while sending.  This means
		in particular, that Zmodem can detect if data is received from the
		remote receiver while streaming a file to the remote receiver.
		Support for such asychronous incoming data notification is needed to
		support interruption of the file transfer by the remote receiver.

		This capapability is not yet supported.  There are only incomplete
		hooks in the code now!  Enable only if you want to see the warning.

config SYSTEM_ZMODEM_SENDATTN
	bool "Attn interrupt"
	default n
	---help---
		Local sender retains an attention string that will be sent to the remote receiver

		This capapability is not yet supported.  There are only incomplete
		hooks in the code now!  Enable only if you want to see the warning.

config SYSTEM_ZMODEM_ALWAYSSINT
	bool "Send ZSINIT"
	default y
	---help---
		Always send ZSINIT header

config SYSTEM_ZMODEM_TIMESTAMPS
	bool "File timestamps"
	default y
	depends on RTC
	---help---
		File timestamps may be supported

config SYSTEM_ZMODEM_SENDATTN
	bool "Send Attn string"
	default n
	---help---
		Send attention string not yet supported

config SYSTEM_ZMODEM_FULLSTREAMING
	bool "Full streaming"
	default n
	---help---
		Full streaming is not yet supported

config SYSTEM_ZMODEM_SENDBRAK
	bool "Can break"
	default n
	---help---
		Can not yet send BREAK

config SYSTEM_ZMODEM_RESPTIME
	bool "Response time"
	default 10
	---help---
		Response time for sender to respond to requests.

config SYSTEM_ZMODEM_SERIALNO
	int "Serial number"
	default 0
	---help---
		Receiver serial number

config SYSTEM_ZMODEM_MAXERRORS
	int "Max error"
	default 20
	---help---
		Max receive errors before canceling the transfer.

config DEBUG_ZMODEM
	bool "Zmodem debug"
	default n
	---help---
		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
		option will likely cause you all kinds of problems if you intend to
		use /dev/console to transfer files!

config SYSTEM_ZMODEM_DUMPBUFFER
	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.
