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
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.
