+# NAME
+
+**dlt-control** - Send control messages to DLT Daemon
+
+# SYNOPSIS
+
+**dlt-control** \[**-v**\] \[**-h**\] \[**-S**\] \[**-R**\] \[**-y**\] \[**-b** baudrate\] \[**-e** ecuid\] \[**-a** id\] \[**-c** id\] \[**-s** id\] \[**-m** message\] \[**-x** message\] \[**-t** milliseconds\] \[**-l** level\] \[**-r** tracestatus\] \[**-d** loglevel\] \[**-f** tracestatus\] \[**-i** enable\] \[**-o**\] \[**-g**\] \[**-j**\] \[**-u**\] 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.

+
+# 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
