Break Messages in 3270 Full-Screen Mode
When your workstation message queue is in break mode (you must specify
*BREAK on the CHGMSGQ command), messages appear on the 3270 device
exactly as they appear on the 5250 display. When your workstation is not in break
mode, the following message is displayed: A message has arrived on a message
queue. To continue, press the function key assigned to the help function or the
function key assigned the error reset function. Then use the Display Message
(DSPMSG) command or the function key assigned to the system request function
followed by option 4 (Display message) to view the waiting message. Set the
workstation message queue to break mode to see the messages as they arrive.
Input-Inhibited Light
When using an AS/400 system from a 5250-type terminal, pressing certain keys in
certain situations causes input to be inhibited and the input-inhibited light to be
displayed on the 5250 terminal. When using Telnet server 3270 full-screen mode,
the input-inhibited light is indicated by two asterisks shown in the lower right corner
of the display (see Figure 123).
When the keyboard is inhibited, any keys mapped to the AS/400 function keys are
ignored. The keyboard must be reset by pressing the Enter key or by pressing the
key mapped to the AS/400 Reset key.
