Reads a line from the server connection, and echoes the data.
function InputLn(const AMask: string): string;
Description
InputLn reads a line from the server and echoes it back honoring the backspace character. If AMask is specified, the AMask string is sent to the peer for each character received, instead of the actual characters which are read.
InputLn is useful when obtaining data from a user such as username, passwords, and commands.
