help with timeout in a loop when telneting

hi, i use script to backup config files automatically, but there is a problem occured when i running my scripts.

my code is like this
#$language = "VBScript"
#$interface = "1.0"

Sub Main
On Error Resume Next
' Open the hosts file
Dim fso, f
Set fso = CreateObject("Scripting.FileSystemObject")
Set fileHosts = fso.OpenTextFile("d:\ip.txt", 1)
szHost = fileHosts.ReadLine
Do While len(szHost) > 4
crt.session.connect("/telnet " & szHost)
crt.Screen.Synchronous = True
crt.Screen.Send VbCr
' Commands
crt.Screen.WaitForString "Password:"
crt.Screen.Send "password1234" & chr(13)
crt.Screen.WaitForString "router> "

Set objFSO = CreateObject("Scripting.FileSystemObject")
Const ForAppending = 8
' Create a new file (or overwrite an existing one)
Set objStream = objFSO.OpenTextFile( _
"D:\MyDataFile.txt", _
ForAppending, _
objStream.WriteLine crt.Session.RemoteAddress
' Commands
crt.Screen.Send "exit" & chr(13)
szHost = fileHosts.ReadLine
End Sub
my problem is that when there is an ip in the ip.txt file is cannot be connected, the crt will not timeout, so the script cannot ignore this ip and go to the next. how can i modify the code to let te script ignore the ips that cannot be connected and move on? thank you very much!

Hello keejo.

The solution to the problem you are experiencing with your
script is described in chapter 3.6 or our scripting manual,
which you can find on the following web page:
Does this help you to get past the connections that don't

Thank you
