The status line is divided into two fields. The first and leftmost field is used to display
messages of up to 64 characters in length. The second field displays the current operating
status and usually displays at least one of the following status indicators:
ANSI The emulation is operating in ANSI mode.
BLOCK The emulation is operating in Block mode.
CNTRL Display controls mode activated. In this mode, received control codes
are displayed but not actioned.
CONV The emulation is operating in Conversational mode.
HOLD Hold screen is activated. The emulation stops processing incoming data
when the Ctrl + S keys are pressed in ANSI mode. To release the hold
state and continue normal processing, press Ctrl + Q.
INS Insert mode is activated. In Block mode, keyboard entered characters are
inserted at the cursor position without overwriting already existing char-
acters.
LOCKED The keyboard has been temporarily locked by the application.
NUM Num lock is activated. Num lock is toggled on and off by pressing the
keys Alt + Num Lock.
PROT Block Protect mode enabled. Refer to the Block Mode section on the
next page for details.
When the emulation detects an error, the status line is temporarily replaced by an error line
which displays one of the following messages:
INVALID LANGUAGE SET REQUESTED
You tried to use an invalid national character set.
INVALID DATA
You tried to enter an invalid character in the current field when in Block protect mode.
The Tandem 6530 emulation operates in one of three main modes, Conversational, Block,
or ANSI. Conversational and Block modes are normally used for applications running on
a NonStop host system, and ANSI mode for applications running on the LXN host system.
