I read the FAQ and some archive. But I still have a no dial tone and busy signal detected. I'm behind a PBX, and want to run my Conexant modem with hylafax. So I started mgetty with /dev/ttySHSF0. But without starting hylafax, the simple act of connecting my RJ11 cable on the modem make my phone ligne busy !! Does anyone have an idee ??? Sylvain.
