I changed VAX's databits to 8 through "set". I did logged in to kids with -8 -l kids but still hangul crashed. more info. I am not using modem, means I am login from dummy terminal. I am connected directly, not using PC at this point. I believe IYAGI has to call, or through modem, to access Korean BBS. In this case, I am directly connecting from dummy terminal. thanks.
