说明：
1).msend "12345" "xxxxx:"
向串口输入12345，然后等串口回显“xxxxx:”后，再进行下面的指令，否则一直等待“xxxxx:”.

lesson9 :for循环的学习
for {puts "Start"; set i 0} {$i < 2} {incr i; puts "I after incr: $i"; } {
puts "I inside first loop: $i"
}
//和c一样 有三个条件
;# Because the test is evaluated before the body,
;# this loop won't execute the body of the code.
for {puts "Start"; set i 3} {$i < 2} {incr i; puts "I after incr: $i"; } {
puts "I inside second loop: $i"
}
//不符合条件 直接结束For循环
;# A while loop equivalent to the first for loop:
puts "Start"; set i 0;
while {$i < 2} {
puts "I inside first loop: $i"
incr i;
puts "I after incr: $i";
}
//while 中的 incr用法
==两种for循环的写法
for {set i 0} {$i<=10} {incr i} {#i默认增量是1，即等价incr i 1。注意这个反括号一定要写在这行行末：args: should be "for start test next command"

Q：能不能改为i为我指定的几个数就好。比如我指定i为 3 5 6 7 9这几个数？ 谢谢。
foreach i { 1 3 5 7 9 } {
puts "$i"
}
