You mentioned you have a /dev/ttyS4. Are you certain that is the modem? Can you do: echo ata >/dev/ttyS4 and hear the dial tone? PS: If you do get the dial tone, you'll probably want to follow up right away with: echo ath >/dev/ttyS4 If this command doesn't give you a dial tone, minicom isn't going to help you. -- Janina Sajka, Director Technology Research and Development Governmental Relations Group American Foundation for the Blind (AFB) Email: janina at afb.net Phone: (202) 408-8175 Chair, Accessibility SIG Open Electronic Book Forum (OEBF) http://www.openebook.org
