Hi

I am trying to use your control to communicate with scales via the serial port, but I am having problems where the OnComm event never seems to be fired.

I call the following code when the form loads:
With SComm3
.CommPort = "3"
.Settings = "9600,N,8,1"
.EofChar = 26
.EOFEnable = True
.InputLen = 0
.RTSEnable = True
.RThreshold = 1
.portopen = True
End With

Any help would be much appreciated.

Cheers

Matt

Do you have the control on a form?

How sure are you that data has arrived in the receive buffer.

Just for debuggong. Place a button on the form that reads the data from the serial port. When you think the oncomm event should have been triggered click the button to see if there really is some data.
