Xshell connection to the CentOS VI Editor cannot use the keypad

Inexplicably I xshell, in the Vim editing script, the right keypad can not output numbers, the output is some letters, but also a letter for a line, too 艹 eggs!

Later on in accordance with the normal operation of the procedure, and rebuilt the connection, incredibly found normal!

Think of a worry, only to find that the problem is the character set, the original is not adjusted Xshell character set!

Workaround:

Go in Xshell----Session window----Click the virtual machine you want to open, right-----Select Properties----terminal type is set to "Linux".

There is a problem with the default "xterm" keyboard mapping.
