Perhaps your serial cable is not a null-modem cable, but an interlink cable. These are similar, but has different pin assignments. The former generates a carrier signal but the latter is not. See the FreeBSD Handbook: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/serial.html By the way, if a serial port is set to the console, the port is set to CLOCAL mode (see stty(1)). In this mode, getty(8) can output the login prompt to the port without a carrier signal. --- Watanabe Kazuhiro ([EMAIL PROTECTED]) _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
