Introduction to commonly used terminal emulation programs
Time: 2025-01-14
In the article Switch Console interface type introduction, it is introduced to you that switch console interface needs to use terminal emulation program to log in and manage the switch, and then several commonly used terminal emulation programs are introduced to you.
Regardless of which terminal emulation program you use, as long as you connect to the switch through the serial port, you need to use the serial cable to connect the console port of the switch to the serial port of the computer and check the COM port number in the device manager on the PC, and if you connect to more than one COM port, you need to select the port number according to the actual connection.

1. Hyper Terminal
Hyper Terminal is a tool used in the early windows operating system to interact with the computer command line, allowing users to communicate through a serial port, modem or TCP/IP network, newer versions of the operating system (e.g., windows 7, windows 10, etc.) are no longer pre-installed Hyper Terminal, which is slowly being replaced by third-party software. software. If you want to use it, you can download and install it by yourself.

Table 1 Hyper Terminal Connection Procedure
|
Operation
|
1. Run HyperTerminal application, pop up the input box to input the name, which can be the name of the device or any characters that are easy for the user to distinguish, so that you can quickly locate the device terminal window when running multiple terminals;
|
2. After the connection description is entered, select the port number for connection (selected according to the actual connection);
|
3. select the corresponding port attributes, i.e. the pre-configured communication parameters of the connected device, usually only the baud rate varies among different switches;

3. Tera Term
Tera Term is a simple interface, functional and practical serial debugging tools, mainly used for windows operating system on the serial communication, Telnet and SSH communication, etc., support for logging in to the device through the serial port, but also support through the network to connect to the remote host.

Operation
|
1. Run the Tera Term application, a configuration box pops up, select the connection type and interface number;
|
2. Program configuration default baud rate is 9600, if you need to modify, in the interface menu Setup -> Serial port, configure the port attributes, click Setup -> Save setup, you can save the default configuration for startup;
