See also the comments regarding vt100 wrapping in GNU termcap documentation, e.g., http://www.gnu.org/software/termutils/manual/termcap-1.3/html_chapter/termcap_4.html which says `xn' Flag whose presence means that the cursor wraps in a strange way. At least two distinct kinds of strange behavior are known; the termcap data base does not contain anything to distinguish the two. On Concept-100 terminals, output in the last column wraps the cursor almost like an ordinary `am' terminal. But if the next thing output is a newline, it is ignored. DEC VT-100 terminals (when the wrap switch is on) do a different strange thing: the cursor wraps only if the next thing output is another graphic character. In fact, the wrap occurs when the following graphic character is received by the terminal, before the character is placed on the screen. On both of these terminals, after writing in the last column a following graphic character will be displayed in the first column of the following line. -- Thomas E.
