Dear Warren thank you for your help, following your mail I found an additional strange behavior of my system, when I use cu, two processes are spawned at the same time: (ps aux output) seaman 80719 0.0 0.0 10048 1372 4 S+ 3:35PM 0:00.00 cu -t -eo -l /dev/cuaU0 -s 19200 seaman 80720 0.0 0.0 10048 1360 4 S+ 3:35PM 0:00.00 cu -t -eo -l /dev/cuaU0 -s 19200 on the console shell where cu lives I see: seaman@bluehouse:~$ cu -t -eo -l /dev/cuaU0 -s 19200 can't open log file /var/log/aculog. Connected [Now I Hit ENTER] write: Device not configured Now the communication hold and I can't do nothing anymore, hitting Enter or rebooting the remote device to see the bootstrap output doesn't work. I need to get out with ENTER~. And I get [EOT] about my environment: * cat /etc/devfs.rules [localrules=10] add path 'ugen*' mode 0660 group operator add path 'usb/*' mode 0660 group operator * cat /etc/rc.conf hostname="bluehouse" ifconfig_em0="DHCP" powerd_enable="YES" # Set dumpdev to "AUTO" to enable crash dumps, "NO" to disable dumpdev="NO" wlans_wpi0="wlan0" ifconfig_wlan0="WPA DHCP" background_dhclient="YES" moused_enable="NO" moused_nondefault_enable="NO" hald_enable="NO" linux_enable="YES" dbus_enable="YES" zfs_enable="YES" ntpd_enable="YES" #bitlbee_enable="YES" gateway_enable="YES" pf_enable="YES" pf_rules="/etc/pf.conf" pf_program="/sbin/pfctl" pflog_enable="NO" pflog_logfile="/var/log/pflog" pflog_program="/sbin/pflogd" fusefs_enable="NO" devd_enable="YES" devfs_system_ruleset="localrules" * cat /boot/loader.conf if_wpi_load="YES" nvidia_load="YES" wlan_wep_load="YES" wlan_ccmp_load="YES" wlan_tkip_load="YES" Thank you for your help f.
