# NAME
**dlt-control** - Send control messages to DLT Daemon
# SYNOPSIS
**dlt-control** \[**-v**\] \[**-h**\] \[**-S**\] \[**-R**\] \[**-y**\] \[**-b** baudrate\] \[**-e** ecuid\] \[**-a** id\] \[**-c** id\] \[**-s** id\] \[**-m** message\] \[**-x** message\] \[**-t** milliseconds\] \[**-l** level\] \[**-r** tracestatus\] \[**-d** loglevel\] \[**-f** tracestatus\] \[**-i** enable\] \[**-o**\] \[**-g**\] \[**-j**\] \[**-u**\] \[**-p** port\] hostname/serial\_device\_name
# DESCRIPTION
Send control messages to DLT Daemon.
This is useful when there is no client (e.g. DLT Viewer) available.
It supports several control messages including:
- Setting log level/trace level
- Setting default log level/default trace level
- Enable timing packets
- Store configuration
- Reset to factory default
- Get logging information
**Note** Use -u option instead of hostname/serial\_device\_name if Unix Socket
is used. See example for detail.
## OPTIONS
-v
: Verbose mode
-h
: Usage
-S
: Send message with serial header (Default: Without serial header)
-R
: Enable resync serial header
-y
: Serial device mode
-b
: Serial device baudrate (Default: 115200)
-e
: Set ECU ID (Default: RECV)
-a
: Control message application id
-c
: Control message context id
-s
: Control message injection service id
-m
: Control message injection in ASCII
-x
: Control message injection in Hex e.g. 'ad 01 24 ef'
-t
: Timeout to terminate application (Default:1000)
-l
Set the log level (0=off - 6=verbose, default= -1)
supported options:
-l level -a apid -c ctid
-l level -a abc* (set level for all ctxts of apps name starts with abc)
-l level -a apid (set level for all ctxts of this app)
-l level -c xyz* (set level for all ctxts whose name starts with xyz)
-l level -c ctid (set level for the particular ctxt)
-l level (set level for all the registered contexts)
-r
: Set the trace status (0=off - 1=on, default=255)
supported options:
-r tracestatus -a apid -c ctid
-r tracestatus -a abc* (set status for all ctxts of apps name starts with abc)
-r tracestatus -a apid (set status for all ctxts of this app)
-r tracestatus -c xyz* (set status for all ctxts whose name starts with xyz)
-r tracestatus -c ctid (set status for the particular ctxt)
-r tracestatus (set status for all the registered contexts)
-d
: Set the default log level (0=off - 5=verbose)
-f
: Set the default trace status (0=off - 1=on)
-i
: Enable timing packets (0=off - 1=on)
-o
: Store configuration
-g
: Reset to factory default
-j
: Get log info
-u
: unix port
-p
: Port for TCP communication (Default: 3490).
# EXAMPLES
Change log level of application "APP1" to DEBUG with unix port
**dlt-control -a APP1 -l 5 -u**
Change log level of application "APP1" and context "CON1" to ERROR
**dlt-control -a APP1 -c CON1 -l 2 localhost**
Get logging information of current running applications with unix port (IPC: Unix Socket)
**dlt-control -j -u**
Get logging information of current running applications (IPC:FIFO)
**dlt-control -j localhost**
# EXIT STATUS
Non zero is returned in case of failure.
