Comment (by Chris Johns):

 Replying to [ticket:3695 Sebastian Huber]:
 > The TCP is sometimes not the best choice to transfer this information. A
 UDP transfer should be added on a best effort basis, e.g. lost packages
 are not retransmitted.

 Are we converging on the need for a common transport interface and
 service? I have this interface in libdebugger ...


 I would welcome UDP, termios, bare BSP IO, even USB. I am fine with this
 interface moving and growing.

 >  The receiver should hand over the package loss information to potential
 high level consumers.

 I do not understand this sentence.

 With UDP a 32bit value at the start is worth the extra overhead. A few
 high order bits can be flags, for example overflow, resync, etc and the
 remainder a sequence number to let the remote know if data has been lost.
