I know this is a nitpicky thing, but I bounce back and forth between Linux and that other operating system(Doors?), and the thing that's bugging me is that I can turn off the modem noises in Win95, but I don't know how to reroute them to /dev/null in Linux.
Later, Jerry Boyd
echo ATL0M0 > /dev/modem
... Actually you want to add the L0M0 (those are zeros) to your init strings in whichever Linux programs you're using with your modem (like your PPP chat scripts).
(You many want to check with your modem to make sure it understands these AT commands --- but it should if it's even moderately Hayes compatible).
