Does anyone know how to send control codes like ctl+z through a remote shell in metasploit? Just pressing the buttons doesn't work. I know I can generate the same thing by holding alt and typing 26 on my num pad, but that doesn't work either. To give you an example of what I'm trying to do.
Code:
Microsoft Windows XP [Version 5.1.2600]

C:\Documents and Settings\user>copy con readme.txt
Hello :)
^Z
        1 file(s) copied.

C:\Documents and Settings\user>
Note: the ^Z you see in the code above is what is generated by ctrl+z when in a real command prompt. In this case it's used, follwed by <enter>, to exit the copy con command.
