telent auto-login feature request

Hi, thank you for creating such a great product!
Sometimes, the telnet login device may be some non-standard shell, such as some communication routers and switches. At this time, user login is done through interactive operations.
In linux, we generally use the expect script to simulate interactive behavior to log in.
Some software (such as secureCRT) has a similar automatic login function. The principle is that when the corresponding keyword (such as "Login: ", "Password: ") is displayed on the screen, enter the preset user name and password.

This function is very useful for telnet login in the communication field.Are you considering adding similar features?

No repository file or test is named in the issue. Start by locating the Telnet login flow and the existing handling of interactive prompts, then compare the desired behavior with the expect-script and SecureCRT examples. Done should mean preset responses are sent for prompts such as "Login:" and "Password:" during non-standard shell logins.
