Sending text to MK158 with script

Hi All,

Want to send text to a MK158 Serial-display-kit.

Connected the MK158 with RS-232-wiring with 2 wires (Ground and Data) to the PC.
After sending a text with terminal emulator FOXTerm the text appears to the MK158 terminal.
That works (with WIN7 and 2400 b/s) great.

But sending text from an application (Homeseer) to the display only[color=#FF0040] B~[/color] is on the Velleman-display.

This is the script:

sub main() 
    Dim PortNumber 

    Portnumber = 8

    hs.OpenComPort PortNumber, "2400,N,8,1", 1, "", ""
    hs.SendToComPort PortNumber, "Biertje?"
    hs.Closecomport PortNumber
end sub

Perhaps the script is ok?
But is handshaking needed? Or VCC (+) wiring?
Anybody connected this Velleman-MK158 to a PC ?

Any help appeciated !

There is no handshaking as there are only two wires.
Most likely, the text is sent too fast.
In the original app. for the MK158, there is a small pause between each character.
Please experiment by sending the characters one by one.
Next, you can decrease the pause between each character just until it still grabs them all correctly.
