Hello Does Anybody Get the Embedded programing magizine. The Oct 97 issue has a acticle in it entiled Software-Based Full-Duplex Asynchronous Serial I/O By NICK G. INT VELDT. Here's a software implementation of full-duplex asynchronous serial I/O for the PIC microcontroller. I found the listings on the web site( www.embbeded.com ) but they seem incomplete, some of the interface details were missing from the text file and it did not have the full text of the artilce. I have now ask for a subscription and will be checking for a reprint of the article but I thought maybe someone or the author might have more info on the setup of the code. All the other serial code i have seen is half duplex and using time delays. I would appreciate any help . Thanks Mike Keers
