Usually, pressing the Tab key sends a tab character to the host. Some HP 3000
applications, however, do not interpret the tab character correctly.
This setting specifies whether pressing the Tab key sends the number of spaces needed to move the cursor forward to the next tab stop, rather than sending the tab character. In character/remote mode, the spaces are transmitted to the host computer. If there are no tab stops to the right of the cursor position when you press Tab, the cursor does not move, and no spaces are generated.
This setting reflects the current terminal state, which can be changed
by the host. The associated default setting, saved with the model, is HP
Tab Equals Spaces Default.
