Description Gary Thomas 2013-05-18 13:20:23 UTC 
Before I run 'runqemu' script, I have these settings:
$ stty -a | tee /tmp/stty.before
speed 38400 baud; rows 64; columns 121; line = 0;
intr = ^C; quit = ^\; erase = ^H; kill = ^X; 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;

isig icanon iexten echo echoe echok -echonl -noflsh -xcase -tostop -echoprt echoctl echoke

After running, I have these:
$ stty -a | tee /tmp/stty.after
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;

Note that the erase and kill have been changed :-(  Not a show stopper, but aggravating nonetheless.

Verified on both Fedora 17 and Ubuntu 12.04
