The following section describes additional commands that can be executed with the simultaneous use of the control key.
Entering control mode |
 |
Both a local and remote user can enter CTRL B to initiate a mode change from console mode to control mode.
Halting scrolling |
|
Entering CTRL S causes the AP to stop passing characters from its port queues to the consoles. The queues continue to accept characters from the system. The XOFF is not passed to the system port being used for the transfer.
Allowing scrolling |
|
Entering CTRL Q causes the AP to resume
passing characters from its port queues to the consoles if this was previously stopped by XOFF character. The XON is not passed to the system port being used for the transfer.
Entering escape characters |
|
The escape character CTRL V nullifies whatever character follows it, except for XON and XOFF characters. Any character following a CTRL V has no effect on AP operation.
Changing master consoles |
|
Only one console can operate as the system console at a time. It is referred to as the master. The other, usually the remote terminal, can view data but cannot enter data until it takes control. Break is used to take control back and forth between the system console and an enabled remote console. When the remote console enters Break, it becomes the master console, and vice versa. In order to enter data at the remote terminal, you must press Break.
