urxvt arrow keys do not work in ncurse?

[张韡武]

Hello. I am running urxvt and I have this problem:
     I. run sysinstall;
    II. press down arrow key on my keyboard;
   III. sysinstall quits;

urxvt send escape sequence to applications run inside it, is it true
that some application like sysinstall in freebsd are configured to
ignore escape sequence?

sysinstall probably think it received an ESC and decide to quit, for
normal ncurse application they usually quit after received ESC for one
second but no other keystroke are following. Can I configure FreeBSD to
act this way too?
