I'm new to MSCOMM32. I took some example by doing some searches. I simply what to dial a phone number. I have this code presently:

oPhone=CREATEOBJECT('Form')
oPhone.AddObject('Phone','Olecontrol','MSCOMMLib.MSComm')
oPhone.Phone.CommPort=1
oPhone.Phone.PortOpen=.T.
oPhone.Phone.Output='ATDT123-4567'+CHR(13)
oPhone.Phone.PortOpen=.F.

When I run the program, I see the light changing on my modem but nothing happens. What am I missing?
