该软件的工作特点是完全将可使用的 DSL/ISDN等物理连接模拟成一个标准的老式调制解调器,这样不管你使用哪种线路连接,只需要安装cFos以后当作56KModem来用就可以,不用考虑网络配置等等,全部由cFos自动配置协调.该软件因为是模拟普通Modem所以需要操作系统的拨号网络来协同工作.因此安装之前要检查是否已经安装了拨号网络(拨号适配器)并且该软件要求使用的拨号网络版本最低必须是MSDUN1.3 ,否则即使完成了安装过程,也不能正常工作.程序体积小巧,自带网络防火墙和计费统计功能.
cFos 7.53 build 3092
+ Added new filter option "-force-set-class". By setting this option in a filter expression you can force cfos to set the class of this filter as the main class of the TCP/UDP connection this packet belongs to.See http://www.cfos.de/speed/documentation/filter_expressions.shtml section "RX-priorisation" for more details. Thanks to GB W for inspiration.
x Fixed potentially serious bug in interlocked handling.
x Now handle_mss is 0 by default, i.e. TCP MSS is not changed by cfos.This should fix problems with some strange web sites.
