Data Settings
Note:
Check the serial device’s equipment settings and documentation for the
proper settings. The device port and the attached serial device must have the
same settings.
Baud
The speed with which the device port exchanges data with
the attached serial device.
From the drop-down list, select the baud rate. Most devices
use 9600 for the administration port, so the device port
defaults to this value. Check the equipment settings and
documentation for the proper baud rate.
Data Bits
Number of data bits used to transmit a character. From the
drop-down list, select the number of data bits. The default
is
8
data bits.
Stop Bits
The number of stop bit(s) used to indicate that a byte of
data has been transmitted. From the drop-down list, select
the number of stop bits. The default is
1
.
Parity
Parity checking is a rudimentary method of detecting
simple, single-bit errors. From the drop-down list, select the
parity. The default is
none
.
Flow Control
A method of preventing buffer overflow and loss of data.
The available methods include none, xon/xoff (software),
and RTS/CTS (hardware). The default is
none
.
Enable Logins
For serial devices connected to the device port, displays a
login prompt and authenticates users. Successfully
authenticated users are logged into the command line
interface.
Disabled is the default and is the correct setting if the
device port is the endpoint for a connection.
Hardware Signal Triggers
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.
Modem Settings
Note:
Depending on the State and Mode you select, different fields are
available.
State
Indicates whether an external modem is attached to the
device port. If enabling, set the modem to dial-out, dial-in,
dial-back, or dial-on-demand. Disabled by default.
