# Long time I had this in my private screenrc file. But many people
# seem to want it (jw):
# we do not want the width to change to 80 characters on startup:
# on suns, /etc/termcap has :is=\E[r\E[m\E[2J\E[H\E[?7h\E[?1;3;4;6l:
#termcap xterm ‘is=\E[r\E[m\E[2J\E[H\E[?7h\E[?1;4;6l’
#terminfo xterm ‘is=\E[r\E[m\E[2J\E[H\E[?7h\E[?1;4;6l’
