COM Port Emulator:cFos allows application for serial ports to be used with ISDN and DSL. Dialer Protection: Protect yourself against expensive dialers! cFos can block certain prefixes or warn you when they are being dialed. More info here! Firewall: A small firewall (packet filter) as a first defense against simple attacks from the Net. No substitute for a full-fledged firewall - but definitely a good start! Budget Management: cFos offers an easy, convenient way of managing free time and data volume online. It tracks and displays how many free hours, minutes or megabytes you have remaining. This lets you make the most of the free time or volume you get from your Internet provider. For more info (in German), click here. Channel Bundling: You can configure cFos for multiple COM ports. This will allow simultaneous data transfer through multiple channels by using Multilink PPP for your dial-up network connections. Call Monitor: If you use the "-L4" parameter, cFos will monitor and display all incoming calls. In addition, a LOGFILE.TXT is created and written to disk if you enter "-L1, -L2" or "-L3." Your local area code can be turned off by adding "-h=."But the Call Monitor can do so much more! For instance, you could have incoming calls trigger sounds and launch programs (see also cfini_e.htm).
