Sending Chr(13) is supposed to be equivalent to pressing 'Enter' on the keyboard. However, the program thinks that I am trying to send the string "Chr(13)". How can I go about this problem? Thanks.
Private Sub cmdLogin_Click()
    If Run.Value Then
        progctrfinal = TextBox1.Value
        For progctr = 1 To progctrfinal Step 1
            Call optionStatus(progctr)
        Next progctr
    End If
End Sub

Function CommandCode(PC As Long)
    Dim command As String
    Dim argPassedIn As String

    Debug.Print progctr
    command = Worksheets("GUI").Cells(PC + 1, 2).Value
    argPassedIn = Worksheets("GUI").Cells(PC + 1, 3).Value
    Debug.Print command & " " & (argPassedIn)
    If command = "MySend" Then Call MySend(argPassedIn)

End Function

Function MySend(ByVal data As String)
    DoEvents
    wsTCP.SendData data
End Function

Private Sub optionStatus(ByVal progctr As Long)
    Select Case progctr
        Case 1      
            Login
            Call WaitCurs(20, 51)
            If Not CurPos Then Exit Sub
            
        Case 2
            Call CommandCode(progctr)
          
        Case 3
            CommandCode progctr
'
        Case 4
            CommandCode progctr
            
        Case 5
            Debug.Print "Case 5"
            CommandCode progctr
        
        Case Else
            Debug.Print "No match"
            'Code for any nonmatch
    End Select
End Sub

Is data the string "Chr(13)"? If so, that will be why.

Try

Function MySend(ByVal data As String)
    DoEvents
    If LCase(data)="chr(13)" Then data = Chr(13)
    wsTCP.SendData data
End Function

or some sort of replace if the string can contain other chars + chr(13)

I am not sure whether it's sending the 'Enter' key because it's coming up with some error prompt in the excel sheet.

If I were to do this manually, pressing enter sends me straight to another menu.

Thanks.

Another related question, what if I'm trying to send the key F1, which is a combination of several characters, i.e. Chr(27) & "O" & "P"?
