【Purpose】

       Learning linux command stty for get/set serial uart speed 

【Eevironment】

       Ubuntu 16.04 terminal

【Procdeure】

       example get uart speed:

root@IoTP:~# stty -F /dev/ttyUSB2 -a
speed 9600 baud; rows 0; columns 0; line = 0;
intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^A; eol = <undef>;
eol2 = <undef>; swtch = <undef>; start = ^Q; stop = ^S; susp = ^Z; rprnt = ^R;
werase = ^W; lnext = ^V; discard = ^O; min = 1; time = 0;

example set uart speed:

stty -F /dev/ttyS0 speed 115200 cs8 -parenb -cstopb  -echo
解释：通过stty设置/dev/ttyS0串口， 波特率为115200 ，数据位cs8，奇偶校验位-parenb，停止位-cstopb,同时-echo禁止终端回显。
