  If you are still persuing this, as mentioned,, you need to use ioport.  check out this website

  I had to use it to write a threaded spooler for legacy, expensive serial printers.

    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
