Works great unless we try to send anything big in the outgoing direction, action which results in about 100K going out then the TR on the modem attached to the FBSD box drops closing the connection, and the ppp log gives us a bunch of "modem write- I/O error" messages. We can *receive* big files with no problems, have played with the speed settings in the ppp configuration, have tried the same setup on other harware with the same discouraging results, and don't see a pattern emerging. I'm starting to pull my hair out; can anybody point me at what we should be looking for to track down the problem? Thanks-- Larry Larry Miller Administrador de Redes / Network Administrator Centro de Investigaciones Biologicas del Noroeste, La Paz, BCS Mexico
