The getty will then configure the port and wait for a connection to be made. An active connection on a
serial device is usually indicated by the Data Carrier Detect (DCD) pin on the serial device being raised.
When a connection is detected, the getty program issues a login: prompt, and then invokes the login
program to handle the actual system login.
Note Selecting Terminal Server mode will disable Port Manager for that serial port, so data is no longer
logged for alerts etc.
4.1.6 Serial Bridging Mode
With serial bridging, the serial data on a nominated serial port on one Console Server is encapsulated
into network packets and then transported over a network to a second Console Server, where it is then
represented as serial data. So the two Console Servers effectively act as a virtual serial cable over an IP
network.
One Console Server is configured to be the Server. The Server serial port to be bridged is set in Console
Server mode with either RFC2217 or RAW enabled (as described in Chapter 4.1.2 – Console Server
Mode).
For the Client Console Server, the serial port to be bridged must be set in Bridging Mode:
Select Serial Bridging Mode and specify the IP address of the Server Console Server and the TCP
port address of the remote serial port (for RFC2217 bridging this will be 5001-5048)
By default, the bridging client will use RAW TCP so you must select RFC2217 if this is the Console
Server mode you have specified on the server Console Server
