Thierry Nouspikel has both the RS232 source code and his patch on his website (the itself patch can be a bit difficult to find). The patch is basically in two sections - one part with the interrupt handling code and the other with the clock/baudrate code. I divided the patch, assembled the clock/baud rate portion and separately the entire patch together (I now had three files - RS232, clock/baudrate, and complete patch). I used the RAG Linker to create two files - one with just the clock/baudrate mod and RS232 code and the other with the whole patch and the RS232 code. Then, I removed the first 6 bytes of the both linked files with a hex editor (to remove information created by the Linker) so the file had the correct >AA01 recognition byte as the first byte. I then searched the file for the hex string containing the code for <DEL> and replaced it with the code for the true backspace and replaced it. The end result were the .bin files as I posted previously. Not difficult but just a bit tedious.
