TermDSM Commands
T[RACE] TI[O] TRACEON
T[RACE] TI[O] TRACEON
Starts extended tracing on a selected port of an asynchronous processor
board in a DTC 72MX.
Security level: 2
Syntax
TRACEON dtcnum, boardnum, 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.
boardnum Number of the asynchronous processor board within a
DTC 72MX which contains the port to be traced.
portnum Number of the port on which tracing is to be done. As
you face the back of the DTC, the ports are numbered
from zero beginning at the left of the board.
Description
TRACE TIO is used to specify extended tracing on a selected port of an
asynchronous processor board (mux card) on a DTC 72MX.
Normally traced data is kept in a circular buffer for each port. When
extended tracing on a selected port is specified, the size of the buffer for
the port is extended, while the size of the trace area for the other ports
on the same board is reduced.
Only one port per board may have extended tracing active at one time.
TRACEON starts extended tracing. No trace file is created with the trace.
You need to perform a DUMP PORT to store the trace data into a disk file.
Use TRACEOFF to stop tracing.
NOTE Tracing a port and dumping information pertaining to a port does not
reset (or otherwise affect) the associated device. If you need to reset the
device, use the RESET command.
