How can I get the Winsock error code for a dbExpress connect error?

In case of a connection problem, the dbExpress driver throws a TDBXError but does not include a socket error code. The message is simply:

Unable to complete network request to host “exampledb.local”. Failed to establish a connection

Is there a way to retrieve the underlying socket error when this type of exception occurs?

The stack trace is:
