On a side note, a user just reported an issue with a MC8790V (see the trailing 'V' there), log attached. In this case, the issue is not about using the APP1 port for PPP; the issue is that there is no non-APP port shown, so we don't specify any port being 'primary', and we end up choosing an incorrect one. So, with: ttyUSB3 --> APP1 ttyUSB4 --> APP2 ttyUSB5 --> APP3 We end up getting: tty/ttyUSB4 primary tty/ttyUSB3 secondary tty/ttyUSB4 data And ttyUSB4 doesn't like being the primary port here. Possibly ttyUSB3 should be the one treated as primary? -- Aleksander
