I'd argue that there are soon more people using their serial port for most other things than modems than there are people doing that soon or already now. But who knows... I know users of most other operating systems are able to use their serial ports without administering themselves into a "dialout" group, but they can of course be wrong. >> obstacles for a home desktop user that s/he cannot use a modem >> with a default install of the OS. > > So ask your favourite distribution to add by default to the dialout > group the user created at install time. Yeah next patch set is about helping distros with that by adding the necessary ID_EXTERNAL_PORT and ID_MODEM environment variables so they can easily do that. >> tty[A-Z]*[0-9] and ircomm[0-9]* has nothing implicit in their >> drivers that tells you there is a modem on the other side. > > Serial modems are like this, sometimes you cannot detect them. Can you ever do it? According to some sources Windows sends "ATI0" to external ports to detect modems, but I guess it's after manually requesting some "Wizard" program to look for modems...
