- As long as the modem is configured S0=0, is not currently in a link
- (such as an outgoing PPP connection), and no computer software
- manipulates the call (such as hylafax modem software, which reads the
- modem hardware flags to detect a call and sets up the modem to answer
- it if configured that way), nobody can get at your machine. I believe
- there is typically a relay separating it from your modem circuitry:
- The ring is detected by a separate transformer.
-
- A PPP link means you are a node on their network: read the UNIX
- Security book from O'Reilly to get a start on securing your system
- from such attack.
