SignatureThanks, but I forgot to mention that I need sub-millisecond accuracy
hence wanting to use the 'scope.
Probably rules out using a standard Coms driver too.
Cheers

The other thing to do is to log the timing (current time) to a log file

Hi,
I want to monitor some code to ensure that I have some timing correct. I
was hoping to hook my oscilloscope to a readily available electrical signal
(Such as Serial Port RTS) and to add instructions in my code to set and clear
the appropriate modem port.
Unfortunately the old Turbo Pascal instructions that allowed this, eg
Port[$2FC] := 2) // Set b2 of Modem Register
and
Port[$2FC] := NOT 2) // Clear b2 of Modem Register
but these don't appear to be available in Delphi (not in D5 anyway).
Any solutions please?
Thanks
Colin
