' CopyOutputToClipboard.vbs
'
' Description:
'   This script example is designed to run while connected to a Cisco Pix
'   firewall or other router device.
'   
'   When launched, the following commands are sent to the device:
'      enable
'      configure terminal
'      pager 0
'      show config
'      show serial
'      show sysopt
'      exit
'      exit
'  
'  The results of the 'show config', 'show serial', and 'show sysopt' commands
'  are captured and stored within the Windows clipboard.  A messagebox then
'  displays the contents of the Windows clipboard.
'   
' Demonstrates:
'   - Use of crt.Screen.ReadString to capture output from a command as echoed
'     from the remote system.
'   - How to copy data from a script variable into the Windows clipboard
'     using the crt.Clipboard object (available in SecureCRT 6.1.0 and later;
'     otherwise, the InternetExplorer automation object is used to manipulate
'     the clipboard).
'   - Use of the ReadString method to either look for a shell
'     prompt (so it can be determined when a remote command has
'     completed) or some other entire line of data.
'   - Use of the crt.Version() method to branch based on the version of
'     SecureCRT running the script.
'   - How to use the VBScript Replace() method to substitute text within
'     an existing string.

' Extract SecureCRT's version components to determine how to go about
' getting the current selection (version 6.1 has an ActiveX scripting object
' for accessing the selection, but earlier versions do not)
szVersionPart = Split(crt.Version, " ")(0)
vVersionElements = Split(szVersionPart, ".")
nMajor = vVersionElements(0)
nMinor = vVersionElements(1)
nMaintenance = vVersionElements(2)
