I recently upgraded my trusty old 4.x system to 8.1 and the one little bit
I can't get working is the internal ISA modem in the system. On 4.x it was
detected automatically by the sio driver:
/kernel: sio4: <U.S. Robotics Sportster 33600 FAX/Voice Int> at port
0x3e8-0x3ef irq 5 on isa0
/kernel: sio4: type 16550A
But it doesn't show up with the new uart driver. I tried adding the bits
for it to device.hints and it shows up, but doesn't appear to be correctly
detected and fails to function. I've tried having the modem set to full
PnP and to fixed specification with no change in results.
dmesg contains a few lines like this which may be related:
PnP device failed to report resource data
and pnpinfo spews this:

I checked in the uart driver code and that pnp identifier is included, but
doesn't appear to be detected or attached or something.
I continued on trying to get a modem working, so I went through my big box
of hardware and found several other ISA modems, gave them all a try with
similar results. One I was able to get the uart driver to recognize as a
16550 port as opposed to the 8250 when I hardcoded the hints and the
resources after disabling PNP. But it still doesn't appear to function
correctly.
And finally I gathered up collection of friends old PCI modems, tried each
one in turn and no drivers would attach. (PUC was compiled in). I
discovered that one is supported by the comms/ltmdm port and one by
comms/hcfmdm port, neither of which work on 8.x. The other modems I
couldn't determine which driver, if any would support them.
Can anyone offer suggestions on how to get this going?
