I spent some time this past weekend attempting to get this
Megahertz XJ4288 card to work with FreeBSD 2.2.1 and failed.
Searching the archives on FreeBSD.org pointed me to the PAO
system which I downloaded and installed on this NEC 2635 notebook.
Looks like a lot of work was done in this area. Thank you!
After some fiddling around, I managed to get the thing to at
least be recognized, and maybe even work,
but there are some strange things to report.
1. The first time the card is probed after booting BSD, the
following message appears.
No card in database for ""("")
Previous to installing PAO this message was
No card in database for ""
2. So, I now extract and reinsert card (config line ends in "any")
Card inserted, slot 1
Code 128 not found
code Unknown ignored
Card "Megahertz"("XJ-CC4288") matched "Megahertz"("XJ-CC4288")
crd: IRQ allocation failed.
driver allocation failed for Megahertz(Invalid argument).
This is sort of what was happening pre PAO.
3. So, now change "any" to "5" in config (no quotes of course).
Card inserted, slot 1
Code 128 not found
code Unknown ignored
Card "Megahertz"("XJ-CC4288") matched "Megahertz"("XJ-CC4288")
sio2: Warning: irq_pending error.
sio2: type 16550A
<<< note no "inserted" msg.
And now going into seyon, I find I can type AT commands to the
modem but there is some problem. The "a" of AT echos back
right away but any subsequent character echos are delayed by
one character.
4. Change "5" to "pio"
Card inserted, slot 1
Code 128 not found
code Unknown ignored
Card "Megahertz"("XJ-CC4288") matched "Megahertz"("XJ-CC4288")
sio2: type 16550A
Megahertz XJ-CC4288 inserted. <<< note completion message
Now, in seyon, all seems ok. All typed characters echo correctly
and life is swell.
So, is this normal for PAO? What is happening with the irqs?
FYI here is the config data used (after disabling most things in bios)
