Last reviewed: July 21, 1997
Article ID: Q154979
The information in this article applies to:
  • The Microsoft Network versions 1.2, 1.3, 2.0, 2.5

SYMPTOMS

If you use the Japanese NEC PC-9800 series of computers with MSN, The Microsoft Network, you may receive the following error message when you attempt to connect: 

   Cannot establish network connection to Internet - NEC PC-98 series

CAUSE

The following NEC PC-9800 computers have an 8250 UART chip on communications port 1, which makes it difficult to connect to the Internet with ISDN or 28,800 bps modems:

  • PC-9821 Cx2 / Cb2 / Cx3 / Cb3 / V7
  • PC-9821 Xt13 / Xa12 / Xa10 / Xb10 / Xa9 / Xa7 / Xa7e / Xe10
  • PC-9821 V10 (not the internal modem model C or D)
  • PC-9801 BX4
  • PC-9821 Na12 / Na9 / Na7 / Nx / Ne3 / Nd2 / Lt2

RESOLUTION

Obtain the updated SER8251F.VXD driver from NEC. This driver is available from the following Web page: 

   http://www.microsoft.co.jp/win95/modules/98_158.htm
Some of the models listed in this article have a second communications port with a 16550 UART chip, which should work better for connecting to MSN.

MORE INFORMATION

These computers have been released only in Japan.
