cFos Professional是一个DSL和ISDN的拨号器。你可以用cFos和Windows拨号网络来建立互联网联接。在DSL连接上，cFos和连接在网络适配器上的DSL调制解调器通讯。在ISDN的连接上，cFos使用ISDN卡厂家提供的CAPI驱动。另外，cFos为互联网联接提供流量管理，防火墙以及其它多种功能。流量管理可以给你带来最大的带宽和最低的Ping值。使用ISDN时，cFos会在COM端口虚拟一个调制解调器，这样你就可以使用调制解调器或ISDN的软件。cFos还带有一个ISDN呼叫者监视程序。

+ Filter expressions -s and -d now accept lists of addresses.
+ Added a switch to log all TCP connections with their adresses, ports, statistics, etc. to a disk file.  This may be good if you want to see what happened, when you didn't watch the status window.  The data of the sessions is not saved, only statistics.
  To activate set "spd gset log_sessions 1".  Add a "-save" if you want to keep it activated after a restart.  The disk file is called session_log.txt; you can set it max size with gset variable max_session_log_size, default is 1mb.
+ Added spd command "tcb" to show interactively some of the info that is written to session_log.txt.
x Fixed a crash that happened with dynamic CAPI loading.
x IP reassembly code was broken.  Fixed.

注册机下载: 点击下载

对于很多朋友并不知道怎么试用改注册机，在这里我简单做个说明。

下载注册机，解压到软件安装目录。运行注册机，点击生成注册文件就OK。

如果出现这个提示，CFOS.KEY generated, copy it to your cFos directory and reboot your computer.

那么表示不在正确的安装目录。

最后别忘记重启下电脑  o(∩_∩)o...
