win32 disassociates you from it.
You can either obtain something like ioport whihc punches through
OR
use the win api, search for async / comm (I cant remember the names now)

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
