• The Microsoft Network versions 1.0, 1.05, 1.2, 1.3, 2.0, 2.5

SYMPTOMS

When you are using a modem with a Sierra Semiconductor chip set, you can connect to MSN, The Microsoft Network, but it may take a long time to display a new window and its contents, even though the modem icon on the taskbar shows a nearly continuous green light that indicates that data is being received.

CAUSE

This behavior occurs with modems with a Sierra Semiconductor 14,400 bps chip set. Modems used by MSN contain the Rockwell chip set. The Sierra Semiconductor 14,400 bps chip set is not fully compatible with the Rockwell chip set.

RESOLUTION

To work around this behavior, follow these steps:

1. Click Start, point to Settings, and then click Control Panel.

2. Double-click Modems.

3. On the General tab, click your modem, and then click Properties.

4. On the General tab, click 57600 (or 115200 if it is available) in the Maximum Speed box.

5. On the Connection tab, click Advanced.

6. Click the Use Error Control check box to clear it.

7. Click OK or Close until you return to Windows.

If performance remains unacceptably slow, the only solution is to purchase a modem using a Rockwell-compatible chip set.
