CHANGE.TERMINAL command operands

ALARM(YES | NO)
specifies whether the terminal's alarm is to sound when the keyboard unlocks. When the keyboard is unlocked, you can enter input. If your terminal does not have an audible alarm, the Session Manager still accepts this operand. It has no way of knowing whether your terminal has an alarm.
CONTROL(LAST | seconds)
specifies the maximum time, in seconds, that the keyboard is to remain locked. The Session Manager sets a timer to unlock the terminal keyboard when the time expires. Note, however, that when the keyboard is locked, you cannot enter commands, and attention interrupts will not be processed.
LAST
specifies that the timer is to be set to the last non-zero value entered for the CONTROL keyword of this command.
seconds
specifies that the keyboard is to be unlocked after the specified number of seconds has elapsed. seconds must be an integer from 0 to 999.
DEFAULT(window_name)
The name of the window that you want to be the default window. This window serves as the default window for other Session Manager commands when a window name is entered with the command. The MAIN window is the IBM-supplied default window.
