George,
I downloaded your Extended Foxtools Help file and found it very informative,
In the Dialer.prg, there are some dll commands e.g.
opencomm = RegFn("OpenComm", "CII", "I")
writecomm = RegFn("WriteComm", "ICI", "I")
closecomm = RegFn("CloseComm", "I", "I")

I presume the commands in 'quotes' are DLL commands, rather than Foxtools commands,as I cannot see them anywhere in the Foxtools library.
Where would I get information on DLL commands and their parameters ?

Thanks

Gerard
