Have you got any experience with programming the serial comport of a PC using Delphi3 (and the component TApdComPort from Async Professional !!) If you do can I ask you a question ?!?!? Could you also send your reply's to my email address goofy1@glo.be with the title APDCOMPORT reply ?? I'm asking you this because I get so much mail that I throw a lot of it away before looking at it !! So, I hope to hear from you soon ! Greetings from Belgium from Glenn Goovaerts CIAO
