Virtual Serial Port Driver

[Sargon]

I try to use Eltima - Virtual Serial Port Driver, VB 2008 and Proteus Isis to simulate a serial communication between PC and 16f877.

VB code:

Public Class Form1
    'Dim WithEvents Comm1 As New IO.Ports.SerialPort
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Comm1.PortName = "COM3"
        Comm1.Parity = IO.Ports.Parity.None
        Comm1.BaudRate = 2400
        Comm1.DataBits = 8
        Comm1.StopBits = 1
        Comm1.Open()
        If Comm1.IsOpen = True Then TextBox1.Text = " serial port COM3 is open"

    End Sub


    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        Dim I As Integer
        For I = 1 To 10000
            Comm1.Write("A", "A")
        Next I
    End Sub
End Class

Picbasic code:

Include "PROTON_4.INC"

Dim X As Byte

DelayMS 200
Cls 

Again:  
SerIn PORTC.7, 17197, [ Wait ("A"), X]
Print At 1,1 ,"X= ",  X
GoTo Again

In ISIS Compim port is set to COM3

It does not seem to work...

Hi, its great to see you visiting our forum. Why not try Proton Compiler for FREE? Download the FREE version of Proton Compiler, Its called Amicus18 and its available from HERE Already using proton Compiler??? Get rid of these pesky messages... get LICENSED USER STATUS

Hi,
I have used it between RealBasic and ISIS and it works fine for me, I always use the USART but that should not matter.
Have you checked your VSPE configuration?

Baudmode = 17197 is 1200 baud, your PC application is set up for 2400 baud!

[Sargon]

Wastrix , you are right. I changed the Baudmode to 16780 (Baud = 2400) and still no change.
I attached a zipped folder that contain VB 2008 project, ISIS and Proton files, and also a Printscreen jpg picture.files.zip

Hi,
I have just had time to look at some of the files, am I missing something but the VB form shows port 3 is open, Compim in ISIS is set for port 3 but VSPE is showing port 1 directed to port 2?
I can not do anything about VB2008.

Why not try with hyperterminal first?

Regards,
Bob

[Sargon]

No! The virual port are COM3 and COM4 . I changed the Compim to COM4 and.... IT WORKS! :-)

So, in VB the port is COM3 and in ISIS (Compim) is COM4.

Thanks RGV250. Reading your message I understood that VSPD need two diferent ports ( a pair).

[RGV250]

Hi,
I am not sure how that works unless you have changed the com pair in VSPE to 3 and 4 as well?.

Regards,
Bob

[Sargon]

No, I didn't change them. The Virtual ports was all the time COM3 and COM4 (in the left sidfe of the picture). COM1 and COM2 is on the right side of the picture, near the button "Add Pair" (If I want to add a new pair of vritual ports).

I attached a new picture whit explanations.

Hi,
OK, I see now, I must have a very old version of VSPE.
Anyway, glad it is sorted.
