It's not the terminal emulator that's the problem (at least I don't 
think it is, since you mentioned $TERM, which means that you're probably 
on a Unix, and Unix terminal emulators generally emulate a VT100). By 
default, SIMH 3.7 discards all non-printing characters output on the 
console by the guest system (I'm not sure why this is the default; 3.6 
and earlier didn't do this). The escape sequences are being treated as 
printable since the escape character at the beginning isn't being sent 
to the terminal.
