I have spent nearly 2 days on trying to figure out how to initialise
a TS-ISO485 board on a TS7800 board (debian standard TS installation).

I have tried to find documentation of how to get the board up but
havent found any useful. My best guess seems to be that module
ts7800_isa16550 should be loaded. However, when this module loads it
only installs one serial port. I tried with 2 parameters but
it seems only that the it takes one argument:
modprobe ts7800_isa16550 io=0x398 irq=6 io=0x298 irq=6
(the result is that only the first port loads...)

Now to the strange part, if I do as follow:
modprobe -r ts7800_isa16550
modprobe ts7800_isa16550 io=0x398 irq=6
modprobe -r ts7800_isa16550
modprobe ts7800_isa16550 io=0x298 irq=6

It works! Both ports /dev/ttyS2 and ttyS3 can be accessed!

Even if I now do modprobe -r ts7800_isa16550 the ports still work!
I.e it works even without the module installed!

I have also made a small program that initiate the PC104 bus as
described here in the forum but no change of behavior... I have also
testet both with and without IRQ sharing but no difference..

>From my point of view the above thing with load/unload modules to
initialise the ports looks strange and unlogic behavior!
