Well, I am the one who posted about useing 4 comports simultaneously.
It only required minor modification to the hardware in my case.

Here is what to do:
buy a secondary controller that has user selectable IRQ's, and configure it to 
NOT use IRQ 4 or IRQ 3(these are used by first two serial ports).  Write down 
the configuration.  NOTE TO ALL LINUXERS: good documentation is important!!
keep a log of all changes to your system, and you will eliminate later 
headaches!!!
Now, get .96pl2 or .97(when released RSN) and get a good setserial.c
run that program to configure your ports, and then use them!!
Good luck, and have fun.
if you already have a serial board that is not selectable, e-mail me, and I 
will try to help more.
