Hi, I have a SMS gateway with FreeBSD 8.2 RELEASE on old hardware (Pentium4). It has plugged a modem Enfora SA-EL, GSM-GPRS, via USB. The modem has been working fine for years. However, since it's plugged to this server, the application that manage the modem hangs every one or two days. I'd like to know if there is a way to know exactly if the problem is the USB ports or the modem failing (because has some years now). Some time I have to reset the USB port (using usbconfig) and it works again. Tha bad thing is that the application hangs and cannot reset the modem (using the %RESET AT command). Thanks in advance for your suggestions. Regards Alberto Mijares
