Delphi 3 "communications port interface"

Simple question.

Does delphi3 have an improved interface to the com ports over delphi2?

Delphi2 currently forces you to jump into assembly to access the com port or to use a third party package.

If it does have an improved interface is it easy to use and where can I find more info on it short of upgrading?  I've looked on Borland's web site and found nothing pertaining to this and I don't want to upgrade without knowing.

I don't know What have Delphi3, but you don't need jump to assembly to access the com ports. If You need i can mail to You  example of using com ports in Delphi2.

wrong. delphi2 uses the win32 api. delphi3 uses the win32 api.
so nothing has changed :)

the only thing that changed is the pascal language (a bit), and the VCL. but the VCL is only built upon the win32 API.

now, to answer your question:
mickeysoft has gone the way unix went a long time ago: Both files and comm-ports are handled as a stream of data.

The api-call createFile is used to open a file for reading/writing. Look in the help to see how to use it, but I would recommend buying a 3rd-party component right now. If you didn't know about this api-call, you probably haven't done this before. comm-port stuff is a drag to debug. Buy yourself a good component. www.activex.com is a good point to start.

Thanks.

I was confused by an article in "Nuts & Volts" May 1997 page 10.

"Delphi 2.0, for creating 32-bit programs, has no port functions builtin, but you can access ports using in-line assembly code in your programs."

I am sure there right also, but I am trained more in computer interfacing then programming and it seems alittle confusing to me.

I just wanted to add this and I'll give you a grade of excellent in a couple days.

I would really appreciate it.

My email address is:

I am trying to put together a software package that will interface with a radio transmitter.  I need to output a digital data stream.

I have a degree Electronics/Computer Technology and have had extensive training in assembly language and some qbasic.  Trying to get anywhere with Windows 95 has been a bit trying.

Any info you have would be appreciated.

thanks
