Configuring Ports
terminated and the port is reset. Allowable values for this parameter are 0 to 255. The default
is 0 (displays as off).
Activity can be set to either input (data received from the terminal), output (data sent to the
terminal), or both. Set the input_is_activity parameter to Y and/or the output_is_activity
parameter to Y.
For a terminal connected to a CLI port, only the input_is_activity parameter needs to be set.
This resets the inactivity timer each time the user types at the terminal. Setting the
output_is_activity parameter resets the inactivity timer when the user receives messages at
the terminal; for example, messages announcing mail has arrived or a batch job has completed.
The cli_inactivity timer specifies the amount of time in minutes that a CLI port with no active
sessions can remain inactive before the Model 5390 server resets the port. Allowable values
for this parameter are 0 to 255, and immediate. The immediate setting directs the Model 5390
server to reset the port immediately after the last session closes. The default is 0.
• To use EIA/hardware flow control (RTS/CTS), set the control_lines parameter to
flow_control, and the input_flow_control and output_flow_control parameters to eia. The
Model 5390 server asserts RTS when it is ready to receive data, and checks the CTS input
before transmitting data.
• To use software flow control (XON/XOFF), set control_lines to none, and set both
input_flow_control and output_flow_control to start/stop. The Model 5390 server sends
XOFF when it does not want to receive any more data; it sends XON when it is again ready to
receive data. When the Model 5390 server receives XOFF, it stops sending data to the port;
when it receives XON, it resumes sending data to the port.
• An attention key, when pressed, notifies the Model 5390 server that the user wants to suspend
an ongoing session with a host and return to the CLI. The Model 5390 server provides three
parameters for defining attention keys: short_break enables the Break key on many terminals;
long_break enables a key that generates a long break; and attn_string defines an attention
character, or string, that produces a break.
• Typically, parameters that display with the show port editing command define characters that
provide CLI line editing functions. Some of these characters are passed as Telnet special
characters with CLI-connected terminals. The CLI-connected terminal is the only terminal that
uses these parameters.
