Very Computer

I can see the modem with pnpdump, but can't seem to get it setup properly in
the isapnp.conf file.  Here's the Errors-

/etc/isapnp.conf:140 -- Fatal - resource conflict allocating 8 bytes of IO
at 100 (see /etc/isapnp.conf)
/etc/isapnp.conf:140 -- Fatal - Error occurred executing request
'<IORESCHECK> ' --- further action aborted

In Windows NT the config looks like this for the resources -

Com3 -
IRQ 5, IO Port 2e8

Here's some info additional info from the linux system using pnpdump to
create the initial isapnp.conf - All are commented, but I have tried all
possible combinations and receive the errors listed above with each
combination.

make sure (ACT Y)   at the end  is  still uncommented and recomment the
selections at the end that refer to 0x0100 and irq 3.

This will set up the same resources as NT, and should be (I think)
/dev/ttyS2.

Then if you get a message about     Fatal - resource conflict allocating 8
bytes of IO      the problem may be with the new version of isapnptools.
My Mandrake dist. has it and it causes isapnptools to look for the address
twice. Its documented in the ISAPNPTOOLS HOME PAGE.

Hope this helps. I just went through this last weekend.
