The dcmecho utility is a command line program that will execute a C-ECHO command as a DICOM Service Class User (SCU - the client) against a DICOM Service Class Provider (SCP - the server). The purpose of the C-ECHO command is to basically 'ping' the SCP to confirm that it is active and accepting associations.
This utility will send the DICOM Echo to the specified remote Application Entity. If <port> is not specified, the DICOM default port 104 is assumed. Also, if no <host> is specified then localhost is assumed.
