DI[AG] PR[INT]

Determines if the connection between a DTC and one of its devices is functioning properly by printing to the device.

Security level: 2.

Syntax

PR[INT] dtcnum,cardnum,portnum

Parameters

dtcnum: The number TermDSM associates with a particular DTC. The DTC command lists each DTC with its assigned number. This list is also printed when you make a mistake while typing in a DTC number.
cardnum: Number of the interface card within the DTC to which the device is connected. The cards are numbered from zero beginning at the bottom of the DTC.
portnum: Number of the port on the interface card. As you face the back of the DTC, the ports are numbered from zero beginning at the left of the board.




	CAUTION: This subcommand aborts the session at the terminal under test. Data for that session is lost.

Description

This diagnostic is supplied primarily for use with devices that do not support loopback tests, such as serial printers, or unsupported terminals.

When the subcommand is entered you will be asked:

Do you want to stop looping if an error is found (yes/no)?

If you answer yes, the series of print operations will stop if an error is encountered. For example, you specified you want the test to run 10 times and an error is encountered in the third printing. If you answered yes to this last question, the remaining seven tests will not be run. If you answered no, all 10 print operations will be executed regardless of the results of each test. The following is then printed on the terminal:

     Please connect and make ready (power on, remote mode, etc.) a      supported printer (or terminal), before answering the "How many      times?" message. (TDSM 115)

How many times do you want to repeat this operation?

You should then enter how many times you want to run the print operation. Enter a number between 1 and 65535. Then the following is displayed:

Type CONTROL_Y to stop the looping.

Any time that you want to stop the diagnostic, press [CTRL]-Y. The diagnostics prompt will be printed and you will be allowed to enter another subcommand.

The Print subcommand sends the following string of characters to the device:

JKLMNOPQRSTUVWXYZ[\]^_'abcdefghijklmnopqrstuvwxyz

If TermDSM knows that this test has failed, an error message will be printed listing the reason for the failure and how many milliseconds the test ran before failing.




	NOTE: If the test passes according to TermDSM, then it is your responsibility to inspect the output of the test to see if it matches the string of characters listed above. TermDSM cannot know the final outcome of the test; therefore, the only way to be sure that the test was successful is through visual inspection.

The diagnostics prompt will be printed on the terminal in order to allow you to enter another subcommand.
