upload config.txt <TFTP-Ipaddress> [<remotefilename>], where TFTP-Ipaddress is
the IP address for the TFTP server and remotefilename is an optional parameter specifying the
filename to store the file as on the TFTP server if a different name than config.txt is wanted. Please
refer to Appendix B for an example of how to install and set up a TFTP server.
If it is not possible to upload the VSAT configuration file to a TFTP server; the config.txt file might
be dumped to the RS-232 port / HyperTerminal by using the CLI command type config.txt.
The output from the HyperTerminal Windows can then be copied to a text file or dumped using the
capture text feature of the HyperTerminal.
