6 echoscu - DICOM verification (C-ECHO) SCU
7
9 echoscu [options] peer port
10
12 The echoscu application implements a Service Class User (SCU) for the
13 Verification SOP Class. It sends a DICOM C-ECHO message to a Service
14 Class Provider (SCP) and waits for a response. The application can be
15 used to verify basic DICOM connectivity.

155 DICOM Conformance
156 The echoscu application supports the following SOP Classes as an SCU:
157 VerificationSOPClass 1.2.840.10008.1.1
159 Unless the --propose-ts option is used, the echoscu application will
161 only propose the transfer syntax
162 LittleEndianImplicitTransferSyntax 1.2.840.10008.1.2
164
166 The level of logging output of the various command line tools and
167 underlying libraries can be specified by the user. By default, only
168 errors and warnings are written to the standard error stream. Using
169 option --verbose also informational messages like processing details
170 are reported. Option --debug can be used to get more details on the
171 internal activity, e.g. for debugging purposes. Other logging levels
172 can be selected using option --log-level. In --quiet mode only fatal
173 errors are reported. In such very severe error events, the application
174 will usually terminate. For more details on the different logging
175 levels, see documentation of module 'oflog'.
176 In case the logging output should be written to file (optionally with
178 logfile rotation), to syslog (Unix) or the event log (Windows) option
179 --log-config can be used. This configuration file also allows for
180 directing only certain messages to a particular output stream and for
181 filtering certain messages based on the module or application where
182 they are generated. An example configuration file is provided in
183 <etcdir>/logger.cfg).
184
186 All command line tools use the following notation for parameters:
187 square brackets enclose optional values (0-1), three trailing dots
188 indicate that multiple values are allowed (1-n), a combination of both
189 means 0 to n values.
190 Command line options are distinguished from parameters by a leading '+'
192 or '-' sign, respectively. Usually, order and position of command line
193 options are arbitrary (i.e. they can appear anywhere). However, if
194 options are mutually exclusive the rightmost appearance is used. This
195 behaviour conforms to the standard evaluation rules of common Unix
196 shells.
197 In addition, one or more command files can be specified using an '@'
199 sign as a prefix to the filename (e.g. @command.txt). Such a command
200 argument is replaced by the content of the corresponding text file
201 (multiple whitespaces are treated as a single separator unless they
202 appear between two quotation marks) prior to any further evaluation.
203 Please note that a command file cannot contain another command file.
204 This simple but effective approach allows to summarize common
205 combinations of options/parameters and avoids longish and confusing
206 command lines (an example is provided in file <datadir>/dumppat.txt).
207
209 The echoscu utility will attempt to load DICOM data dictionaries
210 specified in the DCMDICTPATH environment variable. By default, i.e. if
211 the DCMDICTPATH environment variable is not set, the file
212 <datadir>/dicom.dic will be loaded unless the dictionary is built into
213 the application (default for Windows).
214 The default behaviour should be preferred and the DCMDICTPATH
216 environment variable only used when alternative data dictionaries are
217 required. The DCMDICTPATH environment variable has the same format as
218 the Unix shell PATH variable in that a colon (':') separates entries.
219 On Windows systems, a semicolon (';') is used as a separator. The data
220 dictionary code will attempt to load each file specified in the
221 DCMDICTPATH environment variable. It is an error if no data dictionary
222 can be loaded.
