Hi, I'm working on a project using a 16c84-10 for serial (rs-232) interface. I'm trying to use AN-555 as a shell but am not having much luck. The main problem I'm running into is that the code was written for a 16c71 using rtcc, which the 84 apparently doesn't have. Does anybody know a good method for using the 84 for this or a similar application? Or has anybody converted this application note for use on a 84? I'm shooting for 96, n, 1, with handshake. At this point I can use any four I\O pins. Any help will be appreciated as I am somewhat pressed for time. Thanks in advance, Dave
