Hi,

        I recently had this problem:  while booting, and probing for sio2 on
the isa bus, I get a "not found at
0x3e8", but I checked with MSD under DOS and this is the correct port
address.  Also, it is set to probe
at irq4, port 0x3e8, which is the setting I use under Windows, which works
OK there.  I think these
settings worked OK under 2.1.5-RELEASE.  Maybe there is a bug, or maybe I
need to set the flags.
If the flags need set, what would be a good set of guidelines to go by?  I'm
still confused after reading
the docs.

        It is a Wang 14.4 Data Fax Modem (Hayes Compatible).  One good thing
to have is a way to probe
some devices without recompiling the kernel entirely.  This might be
accomplished by writing some
test code (with main() fuction) and linking with the sio device driver, or
something like that.

        Any suggestions would be appreciated.

        Thanks

                Donn
