[Wirelessdriver-support] Slightly-OT: Sierra Wireless AC550

[Iain M. <Ds...@Ds...>]

Apologies for the slight abuse of this list, but I don't think I'm *too*
far off-topic, and figure that if I'll find an answer anywhere, it'll
be here.

I have a Sierra Wireless AirCard 550 1xRTT PC Card:

	http://www.sierrawireless.com/ProductsOrdering/AC5501xRTT.asp

which I'd like to get working on my TiBook. It's only officially supported
on Windows, but I found some instructions (which since seem to have
disappeared!) on Sierra's website for getting it to work under Linux. This
involved use of the standard serial_cs kernel module and a CIS file (of which
I have a copy). The following was added to the PCMCIA configuration to have it
recognise the card:

card "Sierra Wireless AirCard 550 A550 Rev 1"
manfid 0x0192, 0xa550
cis "cis/SW_550_SER.dat"
bind "serial_cs" 


How might I go about telling MacOS X.2 to recognise the card as a standard
PC Card serial modem, and maybe to use the CIS file? I figure that if I
get that in place, getting modem scripts to run PPP over it should be
easy...

TIA for any pointers!
