Hello, I am developing a PAM module that is called from OpenSSH server when a ssh-client wants to login in the machine. I want my module PAM to send a message to the ssh-client as soon as the PAM module is called by using the pam_info function, but I have checked that the message is not instantly shown in the client unless I send a prompt. I would like to find a way to send the message instantly
