It is not possible to move the cursor outside the active buffer using ANSI commands #5041

Closed DevTester425 closed 2 months ago

DevTester425 commented 2 months ago

Please describe the solution how to move the cursor to position 1;1 if term.buffer.active.baseY > 0. If this cannot be done by ANSI commands, describe any method.
