BTDT.
You'll be far better off to use a low end AVR with hardware, or software uart, and have THAT act as your uart chip. 

More Brains, More Buffer, Less Bucks!

I agree. You can get a really low end avr for less
than $2.00 USD. Program it to do the task (Whatever
that is...) and then hand the result back to the
parent mcu.

Thanks for all of the replies and help. 
I am reading a serial data stream from a particle counter. They are 
always outputting. So I can read them whenever I want. It starts with 
an "=" and ends with a "CRLF", no handshaking. I massage the data and 
then stream it to a PC for data logging. The data from the counters 
changes slowly, so if I miss a few streams it's ok.
I am opening 6 ports (3in 3out) at the begining of the program and 
read from them when I ready. It seems to be working good so far.

PS
I will look into the hardware solutions if it becomes a problem.
