When I try to tip to a port, I see the following error: tip: /dev/term/x: Permission denied all ports busyThis message is typically seen if another process is running on the port.
Confirm your serial terminal settings to see if the port is locked by ttymon.
The easiest way to check this is via admintool. Type "admintool" from the Solaris root prompt.
Select browse, serial ports and disable the ports for terminal use.
