PURPOSE: Runs diagnostic tests from a remote location.
FORMAT: R R R R RD D D D D
DESCRIPTION: This command is exactly the same command used in
the utility menu and as such it displays the results of the tests on BOTH
the MCG-2 screen and the PC screen. The results of the RS232 loop
test are not sent to the PC as a loop plug cannot be installed while the
PC is connected to the MCG-2. However, if you would like your
software to be able to conduct the RS232 loop test, simply echo back
all characters sent by the MCG-2 after the results of the ROM test. The
test string sequence, in ASCII, is as follows:
(space)1 (space)1 (space)1 (space)1 (space)123456 23456 23456 23456 234567 7 7 7 789 89 89 89 890(space)abcdefghij 0(space)abcdefghij 0(space)abcdefghij 0(space)abcdefghij 0(space)abcdefghijklmnopqrstuvwx klmnopqrstuvwx klmnopqrstuvwx klmnopqrstuvwx klmnopqrstuvwxyz yz yz yz yz
(space)1 (space)1 (space)1 (space)1 (space)123456 23456 23456 23456 234567 7 7 7 789 89 89 89 890(space)A 0(space)A 0(space)A 0(space)A 0(space)ABCD BCD BCD BCD BCDE E E E EFG FG FG FG FGH H H H HIIIIIJJJJJK K K K KLM LM LM LM LMN N N N NO O O O OPQR PQR PQR PQR PQRST ST ST ST STU U U U UVWXY VWXY VWXY VWXY VWXYZ Z Z Z Z
Spaces are 32d (ASCII).
Possible results of the RAM and ROM tests are as follows:
Testing RAM...(space)RAM Test Passed!
Testing RAM...(space)RAM Test Failed.
Testing ROM...(space)ROM Test Passed!
Testing ROM...(space)ROM Test Failed.
Each line ends with a carriage return (13d), linefeed (10d).
One easy way to interpret the results of the tests is to look for either a
period or an exclamation point just before the carriage return, line feed.
