void PikeAero::CTaskTerminal::cursorMoveAbsolute ( CMachine::ubit32  x,
CMachine::ubit32  y 
) [virtual]

Moves the cursor to the specified position (coordinates). If you do not specify a position, the cursor moves to the home position at the upper-left corner of the screen (line 0, column 0). This escape sequence works the same way as the following Cursor Position escape sequence.

void PikeAero::CTaskTerminal::cursorMoveBackward ( CMachine::ubit32  n  )  [virtual]
