With odbc driver of 220.127.116.1113 I have the situation, that the database server is not found, if I use DoBroadcast=direct in the connection string. Using the same string without the DoBroadcast works.
Reason seems to be that 2 DB servers are running on the attempted machine one on default port 2638 and one on alternate port 49157. The DB server I am looking for is running on the alternate port.
Is this a bug or have I misunderstood the concept of DoBroadcast=Direct

When you use the DoBroadcast=Direct connection property you must specify the host and port number that the server is listening on. Another way of thinking of it is that the 'direct' options says 'I know what I am doing; do not do any redirection'. Since you did not specify a port in your connection string the client defaulted to 2638.
As Volker suggested in his comment, if you add the port to the connection string you should be able to connect.

To add to Mark's answer:
I guess the PORT is only needed if the server is not using the default port (2638) - that's a guess, I share @Breck's DIRECT experience:) - From the v11.0.1 docs on SERVERPORT:
In case the client sends a broadcast only to UDP port 2638 by default (which I don't know), it would explain why a server running on a different port would not get that broadcast...
