How to access your comport

How can I access my comport? How can I send bytes to the datatransfer pin? I'm using Delphi 1.0

I've tried writecomm and transmitcommchar (and I've opened the port with opencomm) but I don't think it sends anything. Is there an easier way? I saw something about writefile/ex but couldn't find it in my help.

Look up the Ports array in the online help. Ports gives you direct access to the comm port, but it will only work in a 16-bit Windows environment.
