TermDSM Commands
DI[AG] T[ERMINAL]
DI[AG] T[ERMINAL]
Determines if the connection between a DTC port and a terminal is
functioning properly. TermDSM writes a line of characters to the
terminal and orders it to send that line back. TermDSM then compares
the characters received with those sent.
Security level: 2.
Syntax
T[ERMINAL] 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.
Description
When the subcommand is entered the following question is asked:
Do you want to stop looping if an error is found (yes/no)?
If you answer yes, the series of diagnostics will stop if an error is
encountered. For example, you specified you want the write/read
operation to run 10 times and an error is encountered in the third test.
If you answered yes to the above question, the remaining seven
write/read operations will not be run. If you answered no, all 10
write/read 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 terminal, before answering the “How many times?”
question. (TDSM 114)
How many times do you want to repeat this operation?
You should prepare the terminal and then enter how many times you
want to run this diagnostic function. Enter a number between 1 and
65535. The following is then displayed:
Type CONTROL_Y to stop the looping.
