ZTERM - Interactive Routine Interface
ZTERM Available Commands
RL - Loopback on Primary ZLU
Format:- RL,[LIst/LAtency],[sendmode],[dzlu],[AC],[maxtime]
Reads the ZTERM primary ZLU in a loop re-transmitting each received
message and produces timing statistics. (Use RC to set up the primary
ZLU a s a receiver first if the test is on a terminal). Any messages
received are returned to either their source or, if specified, to the
destination ZLU (dzlu).
The options have the following meanings:
LIst Displaythecontentsofthemessagesaswellasthe
statistical information
LAtency This option enables the roundtrip latency time
measurement in ms. This option cannot be set with the
LI list option. The latency measurement inserts 10
bytes of timing information into the buffer as messages
are sent and compares the time when the message is
received again. The latency measurement will not be
done with buffers shorter than 10 bytes. The latency
statistics are displayed when the RL command
terminates or is terminated.
sendmode The mode as explained under zsend in the ZCOM
routine calls section of the ACC Programmer’s
Reference Guide. Each received message is resent with
this mode.
dzlu TheZLUtowhichthemessageistoberouted(default
to source if not specified).
AC Activate the terminal ZLU after every received
message (restart polling).
maxtime This parametersets a maximum runtime, in seconds. If
this is zero then the command runs without a time
limit, otherwise it will terminate after [maxtime]
seconds.
The display of the message information is controlled by the DI (display)
command.
This is a blocking command and will remain active until a ZCOM call
error is encountered (such as ZCOM shutdown, i err=-2), or unt il a sigint
(usually ^C) is received by ZTERM. It accumulates the number of
