+                           Using rtty
+
+Rtty is a line-based remote shell interface (see rtty(1) for general
+information). This file gives a short introduction to using rtty.
+
+Because rtty is line-based, it is not feasible to use interactive
+programs such as vi(1) on the remote server. For this reason, rtty
+sets TERM to tty43 by default. Neither is it generally feasible to
+take advantage of interactive features of the remote shell, such
+as interactive command history.
+
+Instead, one has to make due with the old line-based tools, which
+are fortunately still included with modern UNIX systems. Here is
+a brief overview:
+
+ Editor: 	ed(1)
+ Pager: 	cat(1), pr(1)
+ History: 	fc (see sh(1))
