From 93901ca4fee8a1ab71cb8b918f3d65404460f9ce Mon Sep 17 00:00:00 2001 From: "Roberto E. Vargas Caballero" Date: Wed, 29 Aug 2012 19:59:43 +0200 Subject: Add HTS sequence This sequence adds a new tab stop in the current horizontal position. This means that tputtab must be look for the next tab stop in the tabs array instead of using a hard coded value offset. Also, CHT sequence XXX message is removed because it is not a vt10x sequence (as far as I know it is a vt50x sequence), and it is not implemented by linux virtual terminal neither by xterm.
