.SH NAME
iiod \- IIO Daemon
.SH SYNOPSIS
.B iiod
[
.I options
]

.SH DESCRIPTION
.B iiod
is a server built on top of Libiio which can share a Libiio context across the
network, USB, or a UART link.

.SH COMMANDS
.TP
.B \-V, \-\-version
Display the version of this program.
.TP
.B \-d, \-\-debug
Use alternative (incompatible) debug interface.
.TP
.B \-D, \-\-demux
Demux channels directly on the server.
.TP
.B \-i, \-\-interactive
Run iiod in the controlling terminal.
.TP
.B \-a, \-\-aio
Use asynchronous I/O.
.TP
.B \-F, \-\-ffs <arg>
Use the given FunctionFS mountpoint to serve over USB.
.TP
.B \-n, \-\-nb\-pipes <arg>
Specify the number of USB pipes (ep couples) to use.
.TP
.B \-s, \-\-serial <arg>
Run iiod on the specified UART.
.TP
.B \-p, \-\-port <arg>
Port to listen on (default = 30431).
Using --port 0 will pick an ephemeral port (dynamic / unused in the range between 32768–60999).
.TP
.B \-u, \-\-uri
The Uniform Resource Identifier
.I (uri)
for connecting to devices, can be one of:
.RS
.IP ip:[address]
network address, either numeric (192.168.0.1) or network hostname
.IP ip:
blank, if compiled with zeroconf support, will find an IIO device on network
.IP usb:[device:port:instance]
normally returned from
.B iio_info -S
.IP serial:[port],[baud],[settings]
which are controlled, and need to match the iiod (or tinyiiod) on the other end of the serial port.
.RS
.IP [port]
is something like '/dev/ttyUSB0' on Linux, and 'COM4' on Windows.
.IP [baud]
is is normally one of 110, 300, 600, 1200, 2400, 4800, 9600, 14400, 19200, 38400, 57600, 115200 [default], 128000 or 256000, but can vary system to system.
.IP [settings]
would normally be configured as '8n1' this is controlled by:
.RS
.IP data_bits:
(5, 6, 7, 8 [default], or 9)
.IP parity_bits:
('n' none [default], 'o' odd, 'e' even, 'm' mark, or 's' space)
.IP stop_bits:
(1 [default, or 2)
.IP flow_control:
('0' none [default], 'x' Xon Xoff, 'r' RTSCTS, or 'd' DTRDSR)
.RE
.RE
.IP local:
with no address part. This is the default.

.SH RETURN VALUE
If the specified device is not found, a non-zero exit code is returned.
