Waiting for comms to interpret data
If the data read from the fifo by the comms at this point then the kernel displays the message :
Re-run will start the test again from the beginning while continue will enter the test select menu.
Bad data received re-run >
from COMMS Press to continue >
If the data read by the comms was OK then the comms fills up its fifo with data and the kernel reads
and checks the data. The kernel displays the following screen during this part of the test:
Reading data from comms fifo
If the comms has filled up its fifo and the fifo does not register full then the kernel is told and the
following is displayed:
FIFO2 does not report re-run >

If the data from the comms checks out then the following screen is displayed and the kernel waits
for the user to press the continue key (key 4) before displaying the test select menu.
TEST 26 : mute/tl
Reading data from comms fifo
Okay.. Press to continue >
This test requires the the 15-way Bus A and Bus B ESbus connector dongles, detailed in Appendix
A which ‘diode ORs’ the tlext and mute lines into the drecon line. The routine selects bus A, sets the
mute and tlext lines low and enables the drecon interrupt. The following screen is displayed while
this test is running:
Checking TlExt and Mute lines
Test 26
The processor interrupts are enabled and the tlext line is toggled high and then low and the
processors interrupt is disabled. If no drecon interrupt was received then the processor will display
the following and wait for the user to press the re-run key (key 3), when the test will be repeated, or
the continue key (key 4) to run the mute test.
TlExt on Bus A faulty re-run >
Test 26 Press to continue >
The mute test follows the same pattern as the tlext test. If no drecon interrupt is received when the
mute line is toggled then the following is displayed:
Mute on Bus A faulty re-run >
Test 26 Press to continue >
