I think I have that set up OK. The interruptions are coming from esoteric modem negociation problems, I think. The modem card asks for retrains and eventually the modem on the other end won't do one. Or the cellular connection gets very bad or goes away. One question is, what is the best kind of modem to use on the other end of a cellular connection? I understand that a cellular-specific protocol called ETC will help, and I know that my old Zoom modem doesn't grok it. What modems do? How much does it help? -Greg To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
