Examples	Serial port configuration settings
	The following “set ia” commands show the default serial-port configuration
	settings for the Digi Connect WAN IA:
	set ia serial=1 active=on type=slave protocol=modbusrtu table=1
	set ia serial=1 messagetimeout=2500 slavetimeout=1000 chartimeout=20
	set ia serial=1 priority=medium idletimeout=0
	set ia serial=1 errorresponse=off broadcast=replace fixedaddress=0
	set ia table=1 route=1 active=on type=serial protaddr=0-32 port=1
	Note that future Digi Connect WAN IA firmware releases will expose these
	configuration settings in the Web user interface.
	Enable a Modbus/RTU serial master
	To enable a Modbus/RTU serial master instead, change the configuration
	settings by entering the following “set ia” commands via Telnet. These
	“set ia” commands change the serial device type from slave to master. In
	addition, to handle cellular latency, a timeout value of 31 seconds or longer
	is needed. In addition, the first route, which forwards requests to the serial
	port, can be turned off.
	set ia serial=1 type=master messagetimeout=31000
	set ia table=1 route=1 active=off
