IUCV 2WAY SEND

[bluecmd]

Need a way to do 2WAY SEND as TCPIP relies on that.

The branch hack has some work that goes towards that (as does a branch with the same name in iucv-go).

Right now the initialization is rejected with BAD INIT MSG LEN however, so need to fix that.

[bluecmd]

Could it be that the error is a response to some other send() that is being done, e.g in connect()?

[bluecmd]

No, I changed the debugging to log any IUCV B2F0 call:
