TWinaxial Printer Interface Test (PRTAPOLL)
The twinaxial printer interface test program (PRTRPOLL)
exercises the twinaxial interface by repetitively transmitting
a command when the twinaxial interface is failing.
To load the twinaxial printer interface test program, do the
following:
1. With a load prompt displayed, insert diagnostic
diskette 1 into a diskette drive.
2. Enter the name PGM LOAD.
3.
When the PGMLOAD menU is displayed, select
option 5 (PRTRPOLL) .
.If the PRTRPOLL program does not detect a twinaxial prin-
'ter interface problem and no other error occurs while the
program is running, the program will terminate and the
following message will be printed:
'PRTRPOLL Test - interface did not fail - load and run
TPRNT or go to the system entry MAPs'.

If the PRTRPOLL program does not detect a twinaxial prin-
ter interface problem, but another error occurs while the
program is running, the program will terminate and the
following message will be displayed:
'Hardware error-restart or run TPR NT or go to the
system entry MAPs'
If PRTRPO LL program does detect a twinaxial printer
interface problem, the program will not-terminate.
To terminate the continuously running program, do
either of the following:
• Press the Print key. This will allow either a restart of
the program or an exit from the program.
• Press the Cmd key followed by the End of Job key.
This will terminate the program.
