SecureCRT突然卡死的问题

SecureCRT作为著名的SSHclient，经经常使用于登陆远程server。

在上面编辑文本，特别是用vi打开两个文本，而且须要切换时。非常easy出现卡死的现象，不能接受不论什么的键盘输入。

非常是郁闷。曾经每次遇到这个问题。我仅仅有关掉那个session又一次打开一个。这次又遇上，是在不能忍，试着解决一下。

细致观察会发现，在vi下切换文本“ctrl+w+w”时，非常easy输入成”ctrl+s”。随便拿一个session试试就发现，果然是ctrl+s在作怪。仅仅要输入这个，就会卡死。搜索了一下，发现果然是有原因的:

”

CTRL-S and CTRL-Q are called flow-control characters. They represent an antiquated way of stopping and restarting the flow of output from one device to another (e.g., from the computer to your terminal) that was useful when the speed of such output was low. They are rather obsolete in these days of high-speed networks. In fact, under the latter conditions, CTRL-S and CTRL-Q are basically a nuisance. The only thing you really need to know about them is that if your screen output becomes “stuck,” then you may have hit CTRL-S by accident. Type CTRL-Q to restart the output; any keys you may have hit in between will then take effect.

”

ctrl+s是一个古老的shell控制键，在输入ctrl+q就能够恢复了。呵呵，下次遇到就轻松搞定了。

这个也告诉我们，发现问题要去尽快解决。而不是搁置无论，总有一天令人无法忍受或者愈发严重。
