Using Control Commands
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.
