Operating Procedures
If online rules A apply (A appears in the operator status row), press the Alt and Sys Rq
(System Request) keys to send the CPU a message that the display station may be failing
or that a test request message is on the screen. If online rules B apply (B appears in the
operator status row), press the Alt and Sys Rq keys to clear the display station and
switch the display station between the control (or master) program and application
programs. Contact your supervisor or refer to a system user’s guide for further infor-
mation regarding this key combination.
Print Function
The display station can send a print request to the host system or it can print data locally
if it is attached to a local screen printer. A desktop/screen printer must be ordered
separately. To access either host printing or local screen printing, enter Setup mode
and specify the Print mode. (See Setup mode procedures in Chapter 3.) Press the Print
key to initiate the print function.
Extended Select Function
There are two Extended Select functions, Entry Assist and the Response Time
Monitor (RTM).
Entry Assist
The Entry Assist function facilitates the creation and editing of text, such as memos, letters,
and documents. For more information on the Entry Assist function, see Chapter 5.
In order to use the Entry Assist function, the control unit to which your display station is
attached must provide Entry Assist support. Consult your control unit operator’s manual
for further Entry Assist specifications and operating procedures.
Response Time Monitor
The Response Time Monitor (RTM) records the speed of communications between
the devices attached to a valid, properly configured control unit (Memorex Telex 1274
or IBM 3274) and the host CPU to which they are attached. The RTM is accessed and
exited by pressing the Extended Select key (ExSel for 104- and 122-key keyboards,
Alt-ExSel for 102-key keyboards, and EXSEL for 88-key keyboards), followed by the
PF19 or F19 key. Consult your control unit operator’s manual for further specifica-
tions and operating procedures.
