data transparency
During a session, the access server normally intercepts and interprets switch
characters and flow control characters. Users can enable data transparency,
causing these characters to become transparent to the access server. The access
server will not intercept them while they are being exchanged in the user’s
current session, such as during a file transfer or during a block-mode transfer
(where the terminal sends a screen of data to the host application).
