Something is wrong with the way aterm uses the termios interface,
at least on OpenBSD.
Start aterm and watch the output of "stty -a".
The "status" special character is set randomly, more often it is not
even a control character, making it impossible to use certain letters
as program input.
The diff below applies to ${PORTSDIR}/x11/aterm.
Please test and comment, or try to come up with a better fix. :-)
At a glance, get_ttymode() could be returning a termios structure
where the c_cc array is only partially initialized. I'm tempted to
blame it on the macro definitions in rxvt.h, but I don't have the
time to take a closer look now.
(By the way: aterm 1.0.0 would likely have the same problem.)
