SSH connection issue (wodSSH / wodSSH.NET)

When I try to use SSH to connect to a switch which doesn't support SSH my application close with a message

The requested action with this object has failed.:
$Telnet1.Connect

here is a part of my code:
- creating the object and setting some general properties
[code]$Telnet1 = ObjCreate( WeOnlyDo.wodTelnetDLX.1 )
ObjEvent($Telnet1, Telnet1_ )
$Telnet1.Prompt = #
$Telnet1.BackColor = 0x000000
$Telnet1.ForeColor = 0x00FF00
$Telnet1.Rows = 30
$Telnet1.BackLog = 60
$Telnet1.Columns = 200[/code]

- create the GUI
[code]$Telnet1_ctrl = GUICtrlCreateObj($Telnet1, 11, 72, 505, 313)
$Telnet1.HostName = 192.168.0.20 [/code]

- here I start the SSH mode
[code]$Telnet1.Protocol = 4
$Telnet1.Authentication =1
$Telnet1.Login = username
$Telnet1.Password = password
$Telnet1.Enabled = True
$Telnet1.Connect
Sleep(1000)
If $errc <> 0 Then
stat_setdata( Connection Error: &$errc, 0)
Return
Else
stat_setdata( Connected to 192.168.0.20 using SSH , 0)
EndIf[/code]

$errc is the error code returned by this event function:
[code]Func Telnet1_Connected($ErrorCode, $ErrorText)
$errt = $ErrorText
$errc = $ErrorCode
EndFunc[/code]
The point is - the Connect event is not fired and I don't have any idea about what happens ... sure thing my application exits. I would like to get something like an error or an event to be fired (which one?) in this case (remote host not supporting SSH) - so I can detect it and take some action.
I would be grateful if someone could tell me what to do in this case.
Thank you,
