It's not a bug in xterm on itself. If you cat a binary file you
might end up in the same situation.

This shows that it outputs some high-ascii data, which causes the
xterm to stop output. If you do "echo hi > /tmp/aaa" while in this
state (be alert for typos), you see that it still accepts commands,
but doesn't show them anymore.
In other words, don't worry too much about it but make sure you
redirect binary output to files or pipes and not the console.
