Description

There is a DcmTransportConnection::dumpConnectionParameter() method and also a DUL_DumpConnectionParameters() and a ASC_dumpConnectionParameters() function, but none of these seem to be used for most of the networking tools.

One of the few exceptions are storescu, dcmpssnd and dcmpsrcv, which all use ASC_dumpConnectionParameters().

Dumping the connection parameters is especially useful in the context of a secure TLS connection. Here's an example output of storescu:
