Test suite should config ttyUSB0 on host properly.

stty -F /dev/ttyUSB0 -icrnl -ixon igncr -opost -onlcr -isig -icanon -iexten

-echo -echoe -echok -echoke -hupcl -echoctl

Look like following status on my host:

speed 57600 baud; rows 0; columns 0; 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

Yes, adding -echo -echoe to stty config can fix this problem. So close.
