cFos, DSL and ISDN dial-in driver with Traffic Shaping

cFos Professional is a Dial-Up driver for DSL and ISDN. You can use cFos with the Windows Dial-Up Network to establish connections to the Internet.

For DSL connections cFos talks to you DSL Modem which is connected with a network adapter. For ISDN connections cFos uses the CAPI driver provided by the manufacturer of your ISDN card.

In addition, cFos offers Traffic Shaping for Internet connections, a firewall and a lot more features. With Traffic Shaping you get maximum bandwidth with minimal Ping.

For ISDN cFos emulates a modem at a COM port, so that you can use software, which was originally written for modems, with ISDN, too. cFos also has an ISDN caller monitor.
You get 3 products in one:

1. Internet Dial-Up driver for DSL and ISDN with Traffic Shaping
2. COM Port Emulator for ISDN
3. ISDN caller monitor

Popular cFos Features:

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.
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.htm ).
Skins -Display connection status and parameters as animated skins! The Call Monitor and all COM ports each get their own window, which is opened and closed as needed by cFos . More details can be found here .
Time Synchronization - By adding "-jt" as a parameter, you can have cFos keep your computer automatically synchronized with ISDN time, which ensures your PC clock always runs the correct time.
Save Money - If you enter "ATS19=n," cFos will close the connection after n minutes of inactivity. Adding "S74.0=1" will disconnect you only when your current charge unit is over, which ensures your units are used with maximum efficiency and at the lowest cost to you.
Data Compression cFos data compression can be activated ( cFos to cFos ) with the "-43b" parameter and the "AT&K1" command. If your CAPI driver supports CAPI-V.42bis data compression, it can be enabled using the "AT&Q1" command.
Incoming Calls The "ATS10.9=1" command allows cFos to react to incoming calls by generating a ringing signal through the speaker ( cFos /Win). If you copy the CFRING.WAV file into the cFos directory, you can choose from a selection of WAV sounds to be played instead.
Analogue Modem Support - cFos supports CAPI modem emulation . If the CAPI driver of the ISDN card includes this functionality, cFos is capable of calling analogue modems as well as handling incoming analogue calls .
X.31 - Data transfer through the ISDN D-channel.
cFos/ATM - Special cFos version for ATM-based broadband networks .
