The new Telnet feature sounds interesting. Can you give an example of how can this can be used. Maybe a sample script that shows the proper way to be implemented.

Thanks!

Sure. There's a sample actually, though it's only shown when the default config is loaded.

Here's the sample code:

'Retrieve system info via Telnet
'This example code can be adapted to work
'with any device that supports the protocol

'Create internal Telnet object
set objTelnet = Internal.CreateObject("Telnet")

'Set host name and port
objTelnet.Host = Input.Current
objTelnet.Port = 23

'Make connection
objTelnet.Connect

'Wait for login prompt
objTelnet.WaitFor("login:")
'Then send login name
objTelnet.Send("YourUserName" & vbCrLf)

'Wait for password prompt
objTelnet.WaitFor("password:")
'Then send password
objTelnet.Send("YourPassword" & vbCrLf)

'Wait for shell prompt
objTelnet.WaitFor("xsh>")
'Then send command
objTelnet.Send("show sys versions" & vbCrLf)

'Wait for shell prompt (when command finishes)
data = objTelnet.Recv("xsh>")

'Return data and disconnect
Output.Write data
objTelnet.Disconnect
