Sending Control F+Control G via Winsock

[vikoy]

Hi to all!

I'm trying to establish connection in a cisco router which is connected to a switching equipment using reverse telnet. The problem lies upon connection, for me to be prompted by <PLEASE ENTER USER ID by the system I must send Control F and Control G at the same time without an enter key. I'm getting no response from the switch equipment but doing it using the command prompt and telnet it manually it is successful.
Am i sending the correct codes for control F and control G?

Here is the code:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Connect("10.4.16.193 4001") '======IP, Port
Thread.Sleep(3000) '====wait
'SendData(Chr(94) & Chr(70)) 'sendata
SendData("^F")
End Sub

any help will be very much appreciated.

perhaps it would be ^F+^G ? or ^F+G ?

i'd say try a few different things and you're likely to get the right combination

You should be able to use members of the Keys enumeration and a bit-wise Or:

SendData(New String(New Char() {Convert.ToChar(Keys.Control Or Keys.F), Convert.ToChar(Keys.Control Or Keys.G)}))

This will actually create Ctrl+F as a single character, and like wise for Ctrl+G.

Control-G is Chr$(6) [ACK] and Control-G is Chr$(7) [BEL]

I used VB6 and played around with it. Control-G and Control-g are the same code.

Option Explicit
 
Private Sub Form_Load()
  Text1.Text = ""
End Sub
 
Private Sub Text1_KeyPress(KeyAscii As Integer)
  MsgBox KeyAscii
End Sub

EDIT: Took too long to test and look it up

Thanks you Guys,

herewith are the solutions after series of code modification.

SendData(Convert.ToChar(Chr(6))) '==ACK
Thread.Sleep(3000)
SendData(Convert.ToChar(Chr(7))) '==BELL

or ===================================

SendData(Chr(6))
Thread.Sleep(3000)
SendData(Chr(7))
