Using other Communication Devices
During synchronization, the PC Connect (serial) cable must
be connected to your host PC. However, you must disconnect
the serial cable before using the internal modem, IR port or a
network card in your MobilePro.
Setting Up a Remote Connection
In addition to using your MobilePro as a companion PC,
when you travel you can connect by modem directly to an
internet service provider or a network remote access server,
to get email and to view web pages.
Refer to Chapter 5, "Setting Up a Remote Connection" or the
MobilePro 800's online help file (click the MobilePro Online
Help icon on the MobilePro desktop screen) for details.
