Hi, > I am asking if any one has successfully configured a dialup using a > hardware modem that needs to be configured to ttyS4 Which software are you trying to get to recognise the modem on? The last time I used dialup (which was in RH7/8 era), kppp did the job quite nicely, though I cannot remember if it allowed me to change the port the modem was on. Suggestion : symlink /dev/ttyS4 to /dev/ttyS0 (possibly not the best idea in the world though...) TTFN Paul -- Get your free @ukpost.com account now http://www.ukpost.com/
