How to configure Multiport serial ISA card on linux

Hi all,
I am not presently subscribed in this group. But,i like to get some advise on how to proceed on my problem.
It is,currently i have a ISA card(Multiport with uarts PC16550,uPD71501) and its driver in LynxOS.

But now i want to build the driver for it on Redhat linux 9 kernel.
I like to know
1. Is it possible to add the support for this card by doing some modifications in serial.c?
2. If so,any documents/links on which all functions i should need modifications?
3. what about porting the LynxOS driver to Redhat linux?

Experts,kindly suggest an apt method.

Regards,
Manoj
