The VT100 right-margin behavior is NOT correctly described by "xn"; there is NO correct way to completely characterize the VT100's right-margin behavior, which is much weirder than most people realize, solely by means of combinations of termcap capabilities. Here is the VT100 termcap entry we use at BRL; note that it specifies neither "am" nor "xn": # # DEC VT100 # The "vt100" entry supports the Advanced Video Option if present; # however, AVO is not required for correct operation of the "vt100" entry. # The following SET-UP modes are assumed for normal operation: # ANSI_MODE AUTO_XON/XOFF_ON NEWLINE_OFF 80_COLUMNS # Other SET-UP modes may be set for operator convenience or communication # requirements; I recommend # SMOOTH_SCROLL AUTOREPEAT_ON BLOCK_CURSOR MARGIN_BELL_OFF # SHIFTED_3_# WRAP_AROUND_ON # Unless you have a graphics add-on such as Digital Engineering's VT640 # (and even then, whenever it can be arranged!) you should set # INTERLACE_OFF # Hardware tabs are assumed to be set every 8 columns; they can be set up # by the "reset" or "tabs" utility (use vt100-x, 132 columns, for this). # I have included some compatible code in "rs" for the VT640 if you have one. # No delays are specified; use "stty ixon -ixany" to enable DC3/DC1 flow control! d0|vt100|DEC VT100:\ :ae=^O:as=^N:bl=^G:cd=\E[J:ce=\E[K:cm=\E[%i%d;%dH:co#80:cr=^M:\ :cs=\E[%i%d;%dr:ct=\E[3g:DO=\E[%dB:do=^J:ho=\E[H:is=\E<\E)0:it#8:\ :k0=\EOP:k1=\EOQ:k2=\EOR:k3=\EOS:kb=^H:kd=\EOB:ke=\E[?1l\E>:kl=\EOD:\ :kr=\EOC:ks=\E[?1h\E=:ku=\EOA:l0=PF1:l1=PF2:l2=PF3:l3=PF4:LE=\E[%dD:\ :le=^H:li#24:ll=\E[24H:mb=\E[5m:md=\E[1m:me=\E[m:mr=\E[7m:ms:nd=\E[C:\ :nw=\EE:rc=\E8:RI=\E[%dC:\ :rs=^X\E<\E2\E[?9h^]\E^L^X\E[20l\E[?3;9;6l\E[r\E[m\E[q\E(B^O\E)0\E>:\ :sc=\E7:se=\E[m:sf=^J:so=\E[7m:sr=\EM:st=\EH:ta=^I:ue=\E[m:UP=\E[%dA:\ :up=\EM:us=\E[4m:vt#3:xo:\ :cl=\E[H\E[J:\ :bs:kn#4:pt: d8|vt100-w|DEC VT100 with AVO in 132-column mode:\ :co#132:\ :rs=^X\E<\E2\E[?9h^]\E^L^X\E[20l\E[?9;6l\E[?3h\ \E[r\E[m\E[q\E(B^O\E)0\E>:\ :tc=vt100: d9|vt100-x|DEC VT100 without AVO in 132-column mode:\ :li#14:ll=\E[14H:\ :tc=vt100-w:
