Here's some background that might help: The backspace key on a keyboard can be configured (in most terminal emulators) to send either ctrl-H (hex-08) or DEL (hex-7F).
On the Linux system, the 'stty' command displays and configures how certain keys are recognized. For instance, on my Linux system, at the shell, if I enter stty -a (where the "-a" is for "all"), I get: ======================================================== speed 38400 baud; rows 32; columns 100; line = 0; intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>; eol2 = <undef>; swtch = <undef>; start = ^Q; stop = ^S; susp = ^Z; rprnt = ^R; werase = ^W; lnext = ^V; flush = ^O; min = 1; time = 0; -parenb -parodd cs8 -hupcl -cstopb cread -clocal -crtscts -ignbrk -brkint ignpar -parmrk -inpck -istrip -inlcr -igncr icrnl ixon -ixoff -iuclc -ixany -imaxbel -iutf8 opost -olcuc -ocrnl onlcr -onocr -onlret -ofill -ofdel nl0 cr0 tab0 bs0 vt0 ff0 isig icanon iexten echo -echoe echok -echonl -noflsh -xcase -tostop -echoprt echoctl echoke ===================================================== The "intr = ^C" indicates that control-C is to be recognized as the interrupt key, and "erase = ^?" indicates that DEL is to be recognized as the erase (backspace) key. (While it is pretty obvious that "^C" represents control-C, the "^?" is a special case.) You can also use the 'stty' command to change these settings. See the output of man stty for more information. Finally, note that "break" is not really a character. It's a special condition known as a signal. Usually in a network connection these days, it is not even in play. Hope that helps.
