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
(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
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
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
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.
