Thanks to both Cris72 and dsl for your answers. I believe that answers my questions nicely. On the two additional ports I definitely want TTL levels and not RS-232 levels. My error in terminology. The UART is what I am looking for. I will not need to add FIFO to the monodirectional ports, but will have it for the bidirectional port, so memory will nto be an issue. This is going to control a model railroad and use AI to do routing and prevent crashes.
