ties you have set on that connection. Double-check to ensure that you have set
Windows parameters as described in
Appendix: Setting Up Serial Communica-
tions on page 2- 63.

tor.

You Cannot Access the Internet After
Making a Direct or Modem Connection to the 8600Si:
If you are connected to the 8600Si via modem or direct connect, you cannot ac-
cess any other TCP/IP connection . The PPP connection becomes the default proto-
col and the default gateway defaults to the 8600Si unit’s IP address. This means
that all existing network connections point to the 8600Si unit. To correct this:
A) In Start > Settings > Network and Dialup Connections, open the direct or mo-
dem connection you are using to connect to 8600Si.
B) Select “Properties.”
C) Click the tab that reads “Networking.”
D) Highlight “Internet protocol (TCP/IP).”
E) Select “Properties.”
