I'd probably start with minicom or some other terminal emulator to talk to the serial port first, so you can type "AT" at it and see if it responds. Worst case, you can use 'stty' to set the serial port baud rate, and then echo ATDT >/dev/ttyS0 (or whatever your serial port is, and see if the modem picks up and dials. assuming it's got a speaker on by default. Once you're sure the basic serial I/O works, then move upto pppd. - Kevin -- Subscription/unsubscription/info requests: send e-mail with subject of "subscribe", "unsubscribe", or "info" toWear-Hard Mailing List Archive (searchable): http://wearables.blu.org please, Please, *PLEASE* don't subscribe through a forward/false domain
