I take that back. Having looked closer, it turns out the Zaurus was
suspending the card soon after identifying it. That's why dump_cis
didn't produce anything and the "cardctl config" output looked strange.

After a "cardctl resume" the card was much more responsive:

  Socket 0:
    dev_info
      NULL 0ns, 512b
    vers_1 6.1, "Novatel Wireless", "Merlin Ricochet Modem", "NRM6842", ""
    manfid 0x00a4, 0x1aba
    funcid serial_port
    serial_interface
      uart 16550 [space/mark/odd/even] [5/6/7/8] [1/1.5/2]
    config base 0x0200 mask 0x0003 last_index 0x24
    parse error: Invalid argument
    cftable_entry 0x21
      io 0x02f8-0x02ff [lines=3] [8bit] [range]
      irq 3 [level]
    cftable_entry 0x22
      io 0x03e8-0x03ef [lines=3] [8bit] [range]
      irq 4 [level]
    cftable_entry 0x23
      io 0x02e8-0x02ef [lines=3] [8bit] [range]
      irq 3 [level]
    cftable_entry 0x24
      io 0x0000-0x0007 [lines=3] [8bit]
      irq mask 0xffff [level]

cardctl config says:

  Socket 0:
    Vcc 5.0V  Vpp1 0.0V  Vpp2 0.0V
    interface type is "memory and I/O"
    irq 39 [exclusive] [level]
    Speaker output is enabled
    function 0:
      config base 0x0200
        option 0x61 status 0x08
      io 0xf60002f8-0xf60002ff [8bit]


So I guess I should go looking for why the system doesn't want to
recognize it as a modem.

Are the "parse error: Invalid argument" and the "Bad CIS tuple" messages
something to worry about, then?

I hope to get this working. Ricochet is just too good to pass up, and
I'd like to use it with the Zaurus, not just my laptop.

many thanks,
