OK, thanks for the response.

I tried it without the RTS / CTS lines but it still didn't work.

Sorry about the HSER defines, I used them before and I forgot to get rid of them. Even without them and switching the baud rates, though, it still doesn't work.

"You're also not using a MAX232. It should work with a PC using the inverted serial modes, but the voltage levels might not be high enough. You might end up using one. It's always worked for me, but you never know."
Yeah, I may end up with a MAX232. I just want to avoid it if at all possible.

I really don't know where to go from here. Any help or suggestions?

Thanks.
