You're right, but there are two modems in a dialup link.
(The DTE is the local side)
If someone from the internet sends the PC the magic + + + sequence,
(in the right to left direction) Modem1 won't act on it because it
receives it from the line (as stated above), but Modem2 receives it
from the DTE (the local side), so it can potentially act on it.
(assuming Modem2 is a standalone modem that hasn't been configured
properly and without the guard time)
I've been told I'm wrong because the + + + wasn't issued locally
(what ever that means). Am I wrong? Please educate me.
