这几天在使用联通的掌中宽CDMA无线上网卡，但是只提供了Windows下面的驱动程序。Linux下面的驱动得自己生成。
网卡型号：Sierra Wireless AirCard 555R
我的系统，Debian Linux testing
Kernel，Linux debian 2.6.21-2-686 SMP
创建并编辑下面两个文件：
创建/etc/pcmcia/aircard555.conf:
debian:/etc/pcmcia# more aircard555.conf
card "Sierra Wireless AirCard 555"
manfid 0x0192, 0xa555
cis "cis/aircard555.dat"
bind "serial_cs"
创建/etc/pcmcia/cis/aircard555.cis
debian:/etc/pcmcia/cis# more aircard555.cis
dev_info
no_info
attr_dev_info
EEPROM 250ns, 512b
manfid 0x013f, 0x0710
funcid serial_port
vers_1 7.0, "Sierra Wireless", "AirCard 555", "A555", "Rev 1"
config base 0x0700 mask 0x0073 last_index 0x03
cftable_entry 0x20 [default]
io 0x03f8-0x03ff [lines=3] [8bit] [range]
irq mask 0x3fbc [level]
cftable_entry 0x21
io 0x02f8-0x02ff [lines=3] [8bit] [range]
cftable_entry 0x22
io 0x03e8-0x03ef [lines=3] [8bit] [range]
cftable_entry 0x23
io 0x02e8-0x02ef [lines=3] [8bit] [range]
cftable_entry 0x24
io 0x0000-0x0007 [lines=3] [8bit]
然后应该生成文件aircard555.dat，命令如下：
debian:/etc/pcmcia/cis# pack_cis -o aircard555.dat aircard555.cis
但是，我的系统里面的pack_cis程序有问题，所以我是直接从网上下载的，你可以直接从这里下载aircard555.dat文件，拷贝到相应目录即可。
debian:/etc/pcmcia/cis# dmesg -c
debian:/etc/pcmcia/cis#
这是插入网卡，听到两声beep，
debian:/etc/pcmcia/cis# dmesg
pccard: PCMCIA card inserted into slot 0
pcmcia: registering new device pcmcia0.0
0.0: ttyS0 at I/O 0x3f8 (irq = 3) is a 16550A
可以看到系统已将网卡关联到/dev/ttyS0，在你的系统上有可能设备有所不同。
然后，可以使用pppconfig配置连接。

连接网络：
使用pon或者poff连接或者断开网络。
debian:/etc/pcmcia/cis# pon aircard

全部文件下载：aircard555.tgz
参考原地址： http://centerclick.org/aircard555/
如果使用pcmciautils，则直接将文件SW_555_SER.cis放到/lib/firmware/下，插入网卡以后，就会自动关联到设备文件/dev/ttyS0。
