The command parsing in elm.c seems to presuppose that arrow key commands
always start with ESC (\033).  This is not true.  A vt220 in 8 bit mode
uses as the CSI (Command Seqeunce Introducer) the octal \233 to mean
the same thing as ESC[ in 7 bit mode.  A quick and dirty hack to fix
this is to add, in the file elm.c, 
        case '\233':
before line 646
        case ESCAPE: ...

I hope someone in the development team will look at this bug more thoroughly
than I am able to.  There may be other problems of a similar nature elsewhere
in the code.
