COM port programming in delphi 5

Asked By 60 points N/A Posted on -

I have just started learning Delphi 5. My boss wants me to connect and communicate with a device he gave me, through COM port.

The device didn't come with specifications and I have no idea how to start communicating with it! Where can I read about doing this and what is considered best-practice method to go about this?
