TECHNICAL INFORMATION
You can enter the specific address at which you want the program to beginand
end testing, or it will default to the top and bottom of memory if you enter
[RETURN]. To note: the address at which the program uncovers errors, press
the [SPACE] bar. If you wish to input new parameters for beginning and
ending memory to test, press [ESC] and the screen will display blanks for
starting and ending addresses.
If you press [SPACE] to pause, the bottom .line of the screen will display:
TEST PAUSE - [SPACE] continues [CTRL C] aborts [ESC] restarts test
Refer to Section 2.2 and 2.3 of this manual for information on determining the
physical location of the chip which contains the indicated error.
When completed, press [CTRL C). The EXECUTIVE banner will appear on
screen (since the memory test removes the operating system from the RAM
during testing).
4.4 Port Test
4.4.1 Purpose Of Test
This test checks the functioning qualities of the Vector 4 serial ports. It
requires a loopback test plug which is inserted into the RS-232 port to be
tested.
4.4.2 Procedure For Using Port Test
FORMAT:
PORTEST DP SP <R> [RETURN]
The command line format is shown above. The test name is followed by two
required parameters. The first (DP) is the hex port address for the data port,
while the second (SP) is the hex port address for the status port. Generally,
the status port (SP) address is is one higher than the data port (DP).
The optional "R" parameter, shown in angle brackets, causes the test to repeat
until aborted (by pressing any key). When the test is finally aborted, the
repeat option will cause a summary error report to be displayed.
To review the command entry parameters, enter PORTEST [RETURN]. A help
screen similar to the description above will display.
