Here's what I have so far...it works up to the point where it needs to include the IP address but nothing shows up. Obviously, this code was taken from the help, but I may have butchered it.
#include <GUIConstantsEx.au3>
Opt('MustDeclareVars', 1)
Example()
Func Example()
Local $IP, $n2, $msg
GUICreate("My GUICtrlRead")
$IP = GUICtrlCreateInput("", 10, 10, -1, 20)
$n2 = GUICtrlCreateButton("OK", 10, 30, 50)
GUICtrlSetState(-1, $GUI_FOCUS)
GUISetState()
Do
$msg = GUIGetMsg()
If $msg = $n2 Then
Run("cmd.exe")
WinWaitActive("C:\WINDOWS\system32\cmd.exe")
Send("telnet ", GUICtrlRead($IP))
EndIf
Until $msg = $GUI_EVENT_CLOSE
EndFunc
