PRIMARY TERMINAL STATUS
The terminal responds by sending back the following five-
character string:
2624A
You req~est. the first set .of terminal status bytes (bytes (
0-6) by Issumg the followmg escape sequence: .
TERMINAL STATUS
Terminal status is made up of 14 status bytes (bytes 0-13)
containing information such as display memory size,
switch settings, configuration strap settings, and terminal
errors. These 14 status bytes are displayed below the self-
test screen pattern when the "TERMINAL TEST" ( .. ) key
(in the "modes" or "servi ce keys" set of function keys) is
pressed.
There are two terminal status requests: primary
and secondary. Each returns a set of 7 status bytes. The
primary and secondary status bytes are described in the
next few pages.
The terminal responds with an <ESC>\ and seven status
bytes followed by a terminator. A typical primary terminal
status request and response is illustrated in figure 8-1. The
example assumes that the DC 1 handshake is being used and
that the appropriate terminator is a <CR>.
