Hi NG,

When a port number is specifed and if a device is not connected to the port,
function call Set bOpen = PropSetPortOpen( TRUE) crashes. Is there a way of
preventing this crash?

Hello Ravi

My first reaction was, yes there is a way to prevent a crash: connect a
device ;-)

Maybe your clients use w95/98?

Hi Kriss,

I'm testing this piece in Win2k.

We dont want our users to dictate the port (COM1 or COM2) that has to be
used. So I want my code to be in a loop and test the available ports. But
I cant get this to work as it crashes. Any thoughts?

Is there a DoEvents(in VB) equivalent in Centura/Gupta?

Best Regards,

Stefan Beltrame
