simh PDP-11 with xterm Tektronix 4014 emulation

I was given some DEC BASIC source code that was once used on a PDP-11/40 at Auburn University. It was coupled with either a 4010 or 4014 and played a graphical game of golf. That is, it would draw the shape of the green. I've set up simh booting RSTS/E from here ( http://www.eecis.udel.edu/~mader/delta/downloadrsts.html) and am currently running xterm in Tektronix emulation mode. However, all I see when executing the program is garbage, as if the terminal emulator is never escaping to graphics mode. I've tested it separately with the escape character and the garbage seen by means of "cat"-ing a hex-edited file to the screen, with the first character being ctrl-GS. Here are some pictures of the progress: http://imgur.com/a/thaHr I understand there are apparently some limitations to xterm's Tektronix emulation. I read somewhere that the point-plot mode was not implemented, if I recall. Are there other limitations that I should be aware of? If anyone has a 401X and can try this program out on "the real deal," I can supply you with the source code. Bonus points for having four RK05s and an 11/40 to tie it to!
