where:

is the exit error-level (an ASCII decimal value).

Execute Self Test (Esc z)

This command sequence is used at the factory to run self-tests on

terminals (not terminal emulators).

Shift Out to G1 Character Set (S0)

The S0 control character (0EH) shifts the 6530 to the G1 character set.

Thus, graphics characters in the G1 set are displayed on the screen. (The

G1 set is the same as the alternate character set supported on the

workstation or PC.)

The S0 character is interpreted independently of the current state of any

escape sequence. Only graphics characters sent to the display are

affected. Control characters within any escape sequence are not shifted.

Shift In to G0 Character Set (S1)

The S1 control character (0FH) shifts the 6530 to the standard G0

character set.

Function Keys

The user can request an application-defined function by pressing one of

the function keys. In block mode, a number of keys are interpreted as

function keys.These include:

Fl-F16 (unshifted and shifted). On workstation or PC keyboards

with only 10 function keys, the 6530 maps Fl1 through Fl6 to Alt-

F1 through Alt-F6, respectively. On workstation or PC keyboards

with only 12 function keys, the 6530 maps F13 through F16 to Alt-

F3 through Alt-F6, respectively.

Alt-up arrow and Alt-down arrow (unshifted and shifted)

Pg Up, Pg Dn, Alt-Pg Up, Alt-Pg Dn

Ctrl-Ins, Ctrl-Del (if the local function is disabled by the Esc N

sequence; in protect submode, these are automatically defined as

function keys.)

Enter (if the return function Configuration parameter is enabled)
