 hello all,

 i have problem with backspace in freebsd 8.2. when i run a serial
 program to communicate via a serial port to the other system,
 backspace shows ^? in opened terminal.  i use termios and fcntl to
 open, read, write and close serial port. i set erase and erase2 for
 ttyu2(my serial port) but backspace shows ^? yet.

 any body knows what i'm doing wrong? just erase and erase2 should be
 set to backspace works correctly or any other options should be set?

Just run:

stty erase '^?'

in your serial console terminal.  The backspace key sends ^? so you are
seeing it because it's not mapped to 'erase'.
