Lantronix 900-510 manual Hardware Signal Triggers, Modem Settings

8: Device Ports

Show Lines on Connecting

If enabled, when the user either does a connect direct from the CLI or connects directly to the port using Telnet or SSH, the SLB outputs up to 24 lines of buffered data as soon as the serial port is connected.

For example, an SLB branch office manager issues a connect direct device 1 command to connect port 1 to a Linux server.

Then the SLB device user gets a directory with the ls command exits the connection. When the SLB user issues another direct connect device 1”, the output of the ls command (or some portion of it) is output again, so the user can know what state the server was left in.

Hardware Signal Triggers

Check DSR on	If this setting is enabled, the device port only establishes a
Connect	connection if DSR (Data Set Ready) is in an asserted state.
	DSR should already be in an asserted state, not
	transitioning to, when a connection attempt is made.
	Disabled by default unless dial-in, dial-out, or dial-back is
	enabled for the device port.
Disconnect on	If a connection to a device port is currently in session, and
DSR	the DSR signal transitions to a de-asserted state, the
	connection disconnects immediately. Disabled is the
	default unless dial-in, dial-out, or dial-back is enabled for
	the device port.

Modem Settings

Note: Depending on the State and Mode you select, different fields are available.

State

Mode

Indicates whether an external modem is attached to the device port. If enabling, set the modem to dial-out, dial-in, dial-back, dial-on-demand, dial-in/host list, or dial in & dial- on-demand. Disabled by default.

The format in which the data flows back and forth:

Text: In this mode, the SLB branch office manager assumes that the modem will be used for remotely logging into the command line. Text mode can only be used for dialing in or dialing back. Text is the default.

PPP:This mode establishes an IP-based link over the modem. PPP connections can be used in dial-out mode (e.g., the SLB device connects to an external network), dial-in mode (e.g., the external computer connects to the network that the SLB branch office manager is part of), or dial-on-demand.
