hi all i have problem with backspace in serial communication. this is my scenario: i have three box. box number 1 is windows system, number 2 is freeBSD8.2 and number 3 is cisco router. from box number 1 i connect to the box number 2 by putty and run a serial program on box number 2 that connects to box number 3 via a serial card. this serial program uses termios structure and manage opening, reading, writing and closing serial ports.
my problem is: when i connect to box number 2 via putty, everything is okand backspace works correctly but when i run serial program and connect to the box number 3 via it, backspace do not work correctly and print ^? on screen. i searched a lot and check stty erase and erase2 options. moreover i set VERASE in termios too but nothing happened. what is the correct setting for termios to identify backspace as it should be? how can i understand what key mappings is done when i press backspace in box number 1 to erase character in the terminal of box number 3? i think some thing is wrong in termios options that causes mismatch in backspace translation. this problem has kept me busy for more than a month and i really don't know what should i do to solve it. any comments or hints are really appreciated. motlagh _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
