I have a Windows XP laptop with a Cingular wireless PCMCIA card and account so that I can get Internet anywhere via the cellular system. I need to connect the TS1 serial server to the laptop and operate it from a remote location through the cellular network connection. This means opening ports (port forwarding) in the XP machine to let me operate the Digi using the XP machine as a router to the network. Has anyone ever done this? Any advice on configuring the XP machine?
We have a product that has a serial maintenance port on it and talks on the network to a remote server. Some installations have network trouble because of customer firewalls and other processors, like content filters. I need to be able to drop a laptop and DIGI box at a site, plug it into the serial port, and then debug and operate the device from another city where the server is. I can't use the local network because it is so locked-down.
Any advice or help?
