If I read your post correctly, I think you slightly missunderstood what I'm trying to do. I need to use the RX TX pins associated with HSERIN/HSEROUT for another use BEFORE I use them as a serial port. I need to send out a simple series of long pulses through the TX pin to handshake with the host before I switch to 14400 baud serial communications.

I understand about reading the datasheet, however I havent choosen a PIC yet as this is in the early stages of quoting the project and seeing if the customers project is even possible with their budget and pcb size requirements. chances are though, I'll try and get this thing working on a 18F1320 as I have THOUSANDS of them left over from a non paying customer.
