If by 'drop connections' you mean physical loss of line / carrier, then tuning the modem/s to be (preferably much) less aggressive about forcing the modem connection rate high - ie being easily satisfied to drop back to lower rates during hard times - has helped a lot with a dozen or so remote spots hereaboots. Finding the knobs for some modems can be hard. Assuming that V.42 error correction is working properly - forced if need be - there shouldn't =be= any data loss, however slow getting through, this side of protocol timeouts of course. I can't guess your mystery application, but often slower connections are better than dropped ones, or even ones that spend half their time trying to retrain at high rates. cheers, Ian _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "[EMAIL PROTECTED]"
