I have for example a usb 3g modem that sometimes comes up at cuaU1.[0-4] and sometimes cuaU0.[0-4] after bootup. Is there a way to force devd to tell it to use cuaU9.[0-4] or something like that ? ---Mike -- ------------------- Mike Tancsa, tel +1 519 651 3400 Sentex Communications, mike@sentex.net Providing Internet services since 1994 www.sentex.net Cambridge, Ontario Canada http://www.tancsa.com/
