Hardware Signal Triggers
Note: When the DSR signal drops on a device port, indicating that the attached cable has been
disconnected or the attached device has been powered off, the SLC will log the event in the Device
Ports system log and send a slcEventDevicePortAction SNMP trap. The log message and SNMP
trap only occur if there is an active (connect direct or network connection) to the device port.
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 SLC outputs up to 24 lines of
buffered data as soon as the serial port is connected.
For example, an SLC user issues a
connect direct device 1 command
to connect port 1 to a Linux server.
For example, if the SLC user issues the
ls command to display a directory on a
Linux server, then exits the connection, the results of the
ls will be stored in the
buffer. When the SLC user then issues another
direct connect device
1
, the last 24 lines of the ls command is displayed so the user can see what state
the server was left in.
USB Channel Applies to USB device ports only. When a dual channel USB device is connected
to the device port, this allows the user to select which of the channels is the active
channel used for all connections. Only one channel can be active at any time.
Enter the number 1 or 2. The default is 1.
Check DSR on
Connect
If this setting is enabled, the device port only establishes a 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.
Note: Applies to serial RJ45 device ports only.
Disconnect on DSR If a connection to a device port is currently in session, and 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.
Note: Applies to serial RJ45 device ports only.
Assert DTR By default, DTR (Data Terminal Ready) is asserted on a device port nearly all of
the time (except momentarily when a port is opened for operations). Unchecking
this option will deassert DTR, simulating a cable disconnection for the device that
is connected to a device port.
Note: Applies to serial RJ45 device ports only.
