The format of the bit-wise transmission of data is determined by the stop bits,
parity, and data bits parameters. The default settings are 1 stop bit, no parity,
and 8 data bits. Check the equipment documentation for the proper settings.
Each device port may be separately configured as either DCE or DTE.
The DCE setting is used when connecting to a DTE device such as a computer.
The DTE setting is used when connecting to a DCE device such as a managed
switch. The device ports (1-16) are configured as DCE by default. The Power
Manager port (port 17) is configured as a DTE.
The device port flow control setting determines the method of flow control.
The two most common settings are XON/XOFF (a.k.a. software) and RTS/CTS
(a.k.a. hardware). The default setting for the device ports is XON/XOFF. Check
the equipment documentation for the correct flow control setting.
The
INHIBIT DIRECT MODE
setting allows the administrator to turn off port
buffering while a user is connected to the device and is in direct mode. The
device port buffer still collects data while not in direct mode when this setting is
active. It may be desirable to disable direct mode buffering so sensitive data is
not viewable by other users, but alert and panic messages from the attached
device are still stored when nobody is connected. This setting is disabled by
default, so buffer data is collected both in and out of direct mode.
cat
Use
cat <port name or number>
cat <port name or number>
cat <port name or number>

to display the buffer information for that
port.

to clear the buffer for that port.
less
Use
less <port name or number>
less <port name or number>
less <port name or number>
less <port name or number>
to browse the buffer for that port. When
the buffer reaches the capacity of the screen, it pauses; the user can press the
