BackSpace() action

From The x3270 Wiki

In 3270 mode, the BackSpace() action moves the cursor one column to the left. If the cursor is already in the leftmost column, it will wrap to the end of the previous row, or if in the first row, to the bottom row.

In NVT line mode, BackSpace() performs an erase operation, removing the last typed character from the input buffer. In NVT character mode, it sends the Erase character to the host.
