Title: pppsetup.tcz
Description: Dialup configuration utility.
Version: 1.98
Author: Robert S. Liesenfeld, Kent Robotti

Extension_by: mcewanw
Comments: This extension will set up a dial up internet connection.
There are menu entries for setup, connecting and disconnecting.
Files that need to be in backup for configuration to persist
across reboots:
etc/ppp
etc/resolv.conf
usr/local/sbin/ppp-go
If you also include usr/local/bin/ppp-off, you can remove
pppsetup.tcz from the tce directory after setting up the
connection. If you do, menu entries are also removed. So connect
to the internet by typing "sudo ppp-go" in the terminal, and
disconnect by typing "sudo ppp-off."
If you are using tclocal mounting, then /etc/ppp and
/etc/resolv.conf are the only files that need to be backed up.
This extension requires pppd.tczl.
This extension is NOT PPI compatible.
