RTS Signal Acts as

RI

DCD Signal Always On

DCD Signal On when host connection established

Specify this option to make the RTS signal always act as a DCD signal.

Default: Disabled

Specify this option to make the RTS signal always act as a RI signal.

Default: Disabled

When you configure the DTR or RTS signal pin to act as a DCD signal, enable this option to make the DCD signal always stay on.

Default: Enabled

When you configure the DTR or RTS signal pin to act as a DCD signal, enable this option to make the DCD signal active only during active communication.

Default: Disabled

Additional modem You can specify additional virtual modem commands that will affect how

initialization virtual modem starts. The following commands are supported: ATQn, ATVn, ATEn, +++ATH, ATA, ATI0, ATI3, ATS0, AT&Z1, AT&Sn, AT&Rn, AT&Cn, AT&F, ATS2, ATS12, ATO (ATD with no phone number), and ATDS1.

See Virtual Modem AT Commands for a more detailed explanation of the support initialization commands.

Enable Message of When enabled, displays the Message of the Day (MOTD) when a successful the Day (MOTD) virtual modem connection is made.

	Default: Disabled
Enable TCP	Enables a per-connection TCP keepalive feature. After the configured number
Keepalive	of seconds, the connection will send a gratuitous ACK to the network peer, thus
	either ensuring the connection stays active OR causing a dropped connection
	condition to be recognized.
	This parameter needs to be used in conjunction with Monitor Connection
	Status Interval parameter found in the Serial, Advanced, Advanced Settings
	tab. The interval determines how long the IOLAN will wait during inactivity
	before "testing" the connection. It should be noted that if a network connection
	is accidentally dropped, it can take as long as the specified interval before
	anyone can reconnect to the serial port.
	Default: Disabled
AT Command	The amount of time, in milliseconds, before an AT response is sent to the
Response Delay	requesting device.
	Default: 250 ms
Session Strings	Controls the sending of ASCII strings to serial devices at session start as
	follows;
	z Send at Start—If configured, this string will be sent to the serial device
	on power-up of the IOLAN or when a kill line command is issued on the
	serial port. If the "monitor DSR" or "monitor DCD" options are set, the
	string will also be sent when the monitored signal is raised.
	Range: 0-127 alpha-numeric characters
	Range: Hexadecimal 0-FF
	z Delay after Send—If configured, will inset a delay after the string is sent
	to the device. This delay can be used to provide the serial device with time
	to process the string before the session is initiated or terminated.
	Default: 10 ms
