hi all

i have a problem with backspace in serial communications. i have a
freebsd8.2 box with a serial card on it. when i connect to other freebsd
box via serial port backspace does not act as i expected. backspace shows
^? on screen. i searched alot and find out that stty has two parameters
-erase and erase2- to identify erase characters in terminal and they should
be set correctly. i set erase and erase2 to ^? by "stty erase \^?" and
"stty erase2 \^?" commands but nothing happened.
please let me know how i can fix it. i know it is simple issue but i really
do not know how to do that.
