Configuring Ports
Dedicated Ports
The Model 5390 server allows four forms of dedicated ports for use with terminals and modems.
To set a dedicated port:
•
Set the serial line port parameter mode to telnet, tn3270, rlogin, or connect for ports using
the telnet, tn3270, rlogin, or LAT protocols, respectively.
•
Set the speed, data_bits, stop_bits, and parity parameters to match the terminal or modem
used.
•
If the dedicated port is connected directly to a terminal, set the type parameter to hardwired.
The user is registered with the who database according to the input_is_activity and
output_is_activity parameter settings. If neither parameter is set, any user on this port is
invisible to who. If input_is_activity is set, when the user enters data, the line is registered
with the who database (generally used for hardwired CLI terminals). If output_is_activity is
set, the line is registered when the Model 5390 server first sends data (generally used for
hardwired printers or other slave devices). This entry is removed on a hang-up or when the
slave line is released, regardless of the input_is_activity and output_is_activity parameter
settings. If the connection session times out without receiving input from the user, the
Model 5390 server prompts Press return to restart login and then waits for input, or a
hang-up, before retrying the connection.
If the dedicated port is connected to a modem, set type to dial_in. The user is registered with
the who database as soon as a process (CLI or slave) attaches to the line, regardless of the
NOTE:
In earlier software releases, setting the mode parameter to ded-
icated enabled access to a single host. Connection to the host was made
using either the rlogin or telnet protocol. Using telnet, you could con-
figure a TCP port to allow the automatic startup of an application on
the host. (Valid TCP port numbers range from 1 to 65535.) A dedicated
port had two mechanisms for originating the connection, depending on
the setting of the control_lines parameter. If control_lines was set to
modem_control or both, a connection was made automatically when
DCD and DSR were asserted. If control_lines was not set to
modem_control or both, pressing the Return key initiated the connec-
tion. Ports defined as dedicated do not support either host-based secu-
rity or local password protection. For backward compatibility, the
Model 5390 server continues to support the dedicated option for the
mode parameter, but Bay Networks recommends using the newer
options.
