IBM 19K5716 manual No connection to your ISP at 128 kbit/s

3.You are using the correct Dial-Up Networking connection that configured for use with with the PC Card.

4.Your ISP supports the appropriate protocols. The ISP might conceivably recommend any protocol, such as V.120, asynchronous PPP, X.75, or any other protocol. Contact your ISP and find out the protocol to use. Install cFos and create a Dial-Up Networking connection according to the procedures in this guide and your ISP's instructions.

No connection to your ISP at 128 kbit/s

If you suspect that the IBM International ISDN PC Card is only operating using one ISDN B channel (64 kbit/s) although you have configured the system to use both B channels, please verify the following:

1.Your ISP supports multilink connections, a 128 kbit/s connection over two ISDN B channels simultaneously.

2.If you are using Windows 95, make sure you have installed the Microsoft Dial- Up Networking Update 1.3. Various language versions are available on the CD. Installation instructions can be found in Section “Upgrading Dial-Up Networking for Windows 95” on page 18.

3.You have followed the instructions in Section “Setting Up Internet Access” on page 106.

cFos was installed with all COM ports selected. Now my modem takes COM port 10 or higher. How can this be solved?

If you select all available COM ports during the cFos installation, then cFos will occupy all COM ports, up to COM9. This might cause problems later when you install an analog modem. There are two ways to circumvent this problem:

1.Try to use as few COM ports as possible. Three to four COM ports should be enough for day-to-day use of cFos with the IBM International ISDN PC Card.

2.If possible, install the analog modem before you install the IBM International ISDN PC Card and cFos.

3.If you have already installed the IBM International ISDN PC Card, then click Start -> Programs -> cFos ISDN & DSL Driver and select Configure cFos. In the cFos configuration program, select the menu command Configure COM ports. In the list of available COM ports, deactivate the one you want to use for your analog modem. Click OK, then Exit. When asked whether you want to save the changes, click Yes. In the last window, click OK. Restart your computer if necessary.

CAUTION:

When following the instructions above to make a certain COM port available for your analog modem, make sure that the COM port you release is not currently used by one of cFos's emulated modems. You can verify this by clicking “Start / Settings / Control Panel / Modems”. Furthermore, make sure that your Dial-Up Network connections are not using this COM port.
