IO17058: TOUCH SCREEN HUNG ON 745

 

APAR status

  • Closed as program error.

Error description

  • Store 54 (745 pilot store) reported that they found the touch
screen
hung on a 745 terminal.  Terminal 92 had the #1 box on the
keypad on
the touch screen highlighted and the cursor there and the touch
screen
was unresponsive.  I dumped the terminal and two dumps were
listed as
received (one on each controller) so I sent them both in.

Local fix

  • 



Problem summary


    

  •    Operator perceives the touch as unresponsive.
This condition manifest
when at the console driver level a secondary
display mutex is grabbed but
never released, which is caused by a flag bit
that is accidentally cleared
by the mouse ISR.

    



Problem conclusion


    

  •  The mouse ISR should respect the flag bits
set the by the console mouse
ASR, and that it relies on for the
appropriate handling of events. It should
only set those flag bits that it needs and
leave the others unchanged.

    



Temporary fix
