Is there a way to use a login on the serial CLI

I would like to protect the serial CLI just like a telnet CLI where it requires a user login and password. Is there an option to enable that or has it been done? Right now if you connect a computer to the serial port (closing port after boot then calling the api to start the cli) it goes right to the command prompt and is not secure at all. Net_OS 7.5

Hello

 The capability you are looking for is not shipped with NET+OS. The CLI code is shipped in source form and as such you could make any changes necessary to make the component do what you need it to do.
