Note: Depending on the State and Mode you select, different fields are available.
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 console manager 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.
Then the SLC user ls command to display a directory on the Linux server, then
exits the connection. When the SLC user 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.
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.
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.
State Indicates whether an external modem is attached to the device port. If enabling,
set the modem to dial-out, dial-in, dial-back, CBCP server, CBCP client, dial-on-
demand, dial-in & dial-on-demand, dial-back & dial-on-demand, or dial-in/host list.
For more information on the different dialing types, see
Modem Dialing States (on
page 136) . Disabled by default.
Mode The format in which the data flows back and forth:

Text: In this mode, the SLC unit 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 SLC console manager
connects to an external network), dial-in mode (e.g., the external computer
connects to the network that the SLC device is part of), or dial-on-demand.
Use Sites Enables the use of site-oriented modem parameters which can be activated by
various modem-related events (authentication, outbound network traffic for dial-
on-demand connections, etc.). Sites can be used with the following modem
states: dial-in, dial-back, dial-on-demand, dial-in & dial-on-demand, dial-back &
dial-on-demand, and CBCP server.
Initialization Script Commands sent to configure the modem may have up to 100 characters. Consult
your modem’s documentation for recommended initialization options. If you do
not specify an initialization script, the SLC device uses a default initialization
string of
AT S7=45 SO=0 L1 V1 X4 &D2 &c1 E1 Q0 .
Note: We recommend that the modem initialization script always be preceded
with
AT
and include
E1 V1 x4 Q0
so that the SLC console manager may
properly control the modem. For information on AT commands, refer to the
modem user guide, or do a web search for
at command set
