DECSCL—Select Conformance Level

You select the terminal's operating level by using the following select conformance level (DECSCL) control sequences. The factory default is level 4 (VT Level 4 mode, 7-bit controls).

Note

When you change the conformance level, the terminal performs a hard reset (RIS).
