I'm trying to monitor the state of 4 single pole switches through the serial
port with VBA in an Access 2003 Database application.
1) In the MSComm control what property is used to see if the Ring Indicator
is hi or low? It would be the counterpart to DSRHolding, CDHolding and
CTSHolding - I can't seem to find RIHolding. I need a fourth input point.
Is there a property for the Recieve data? If someone can answer this one we
don't need to go to question 2.
2) Failing a ring indicator property I thought I would use the .CommEvent
and monitor for a change in the Ring indicator, but my .CommEvent is
returning a value of 58 all the time - which isn't in the list of expected
events so I have no idea what I need to do next.
